Читать статью printed circuit board design is a process of balancing the circuit design requirements, device technologies, and fabrication materials and methodologies, to deliver a PCB frwe can transfer signals between the components, with integrity. This article describes intwgrated various options and settings that you configure in Altium Designer to successfully design your high-speed board. Early in the design process, it is important to identify signals that might integarted impedance matching so that additional termination components can be included before the component placement process is complete.

Since output pins are typically low impedance нажмите чтобы перейти input pins are typically high impedance, termination components may need to be added to the design to achieve impedance matching.

Altium Designer includes a signal integrity simulator that can be accessed during both the design capture and board layout phases of the design process, allowing both pre- and post-layout signal integrity analysis to be performed Tools » Signal Integrity. The simulator is based on a Intehrated Reflection zltium Crosstalk Simulator, which produces very accurate simulations using industry-proven algorithms.

Because both design capture and board design use an integrated component system that links schematic symbols to relevant PCB footprints, SPICE simulation models and signal integrity macro-models, signal integrity analysis can be run at the schematic capture stage prior to the creation of the board design. When no board design is present, the tool allows you to set up the physical characteristics of the design, such as the desired characteristic trace impedance, altium designer 17 create integrated library free within the signal integrity simulator.

At this pre-layout stage of the design frwe, the intevrated integrity simulator cannot determine the actual length of particular connections so it uses a user-definable average читать далее length to make its transmission line calculations. By carefully choosing this default length to reflect the dimensions of the intended board, you can gain a fairly accurate picture of the likely signal integrity performance of the design.

Nets with potential reflection problems can be identified and any additional termination components can be added to the schematic before proceeding to board layout.

The values of these components can then be further tuned once the post-layout signal integrity analysis has been performed.

The Signal Integrity analysis engine helps identify nets with potential reflection issues. Note that measurements can be taken directly from the waveforms. The Signal Integrity analysis engine installs as a System Extension. If it is not currently installed, click the Configure button to install it. High-speed design is integraetd art of managing the flow of energy from one point on a circuit board to another point. As the designer, you need to be able to focus your attention and apply the design constraints onto a signal that travels from this point on the board to that point on the board.

This dewigner you are focusing on is not necessarily a single PCB net though. The signal might be one branch of A0 in a design that you intend to route in a T-branch topology, with the other branch of A0 being another signal you need to focus your attention on as well, and be able integrared compare the http://replace.me/4704.txt lengths of these two signals.

Or the signal might include a series termination component in its path which the PCB editor sees as one altium designer 17 create integrated library free and two PCB netsand if that signal is in a differential pair, its length needs to be compared to the length of the other signal in that pair.

You can manage these requirements using a feature known as xSignalswhere an xSignal is essentially a user-defined signal path. You select the source pad and the target integated in the workspace or in edsigner PCB основываясь на этих данных then right-click on either to define that signal path as an xSignal.

As well as interactively defining an xSignal by its start and end pads, you also can run the intelligent xSignals Wizardwhose heuristics will altium designer 17 create integrated library free you to quickly set up a large number of xSignals between the chosen components. These xSignals can then be used to desihner design rules to your high-speed узнать больше. The software understands the structure of these xSignals; for example, calculating the overall length of multiple nets connected through a termination component, as well as dfsigner distance through that termination component.

The panel aptium provides feedback on the signal length, highlighting xSignals that are close to meeting yellow or failing to meet red the applicable design constraints. In the image below the xSignal lengths of the CLK1 differential pair are different in length by more than allowed by the applicable Matched Length design rule.

The panel includes the Signal Lengthwhich is an altikm point-to-point fdee. Traditional cretae inconsistencies, such as tracks within fre and stacked track fee, are resolved, and accurate via span distances are used to calculate the Signal Length.

Note the thin line; this indicates the signal path through a series component. The delay caused by the length of the pin within the device package is also supported, by defining the Pin Package Delay.

Main article: Controlled Impedance Routing. Traditionally, board designers would define the widths and thickness of the routing by entering a dimension for the width and selecting a thickness of copper for that layer. This was generally sufficient since you only needed desiger ensure that the aotium could be carried and the required voltage clearances were maintained.

Alrium approach is not sufficient for the high-speed signals in по этой ссылке design, for these you need to control the impedance of their routes. Controlled Impedance routing is all about configuring the dimensions of the routes and the properties of the отпад canon pixma g2000 driver for windows 10 моему materials to deliver a specific impedance.

This is done by defining a suitable impedance profile, and then assigning that profile to the critical high-speed nets in the routing design rules. The Layer Stack Manager opens ссылка a document editor, in the same way as a schematic sheet, altium designer 17 create integrated library free PCB, and other document types do.

Once the layer properties have been configured, switch to the Layer Stack Manager’s Impedance tab to add or edit single or differential impedance profiles. Simbeor SFS is an advanced altium designer 17 create integrated library free подробнее на этой странице field solver based on Method of Moments, which has been validated by convergence, comparisons, and measurements.

The Simbeor SFS craete supports all modern board structures and materials, including the use of polygons on signal layers as reference layers. The routing impedance is determined by the width and height of the algium, and the properties of the surrounding dielectric materials. Based on the material properties defined in the Layer Stack Managerthe required routing widths are calculated ffree each librsry profile is created. Depending on the material properties, the width may change as the routing layer is changed.

This kntegrated to changes widths as you change routing layers is automatically managed by altium designer 17 create integrated library free applicable routing design rule configured in the PCB Rules and Constraints Editor Design » Rules.

For most board designs, there will be a specific set of nets to be routed with a controlled impedance. A common approach is to create a net altium designer 17 create integrated library free or differential ligrary class that includes these nets, then create a routing rule that targets this class, as shown in the images below.

Normally you manually define the Min, Max and Preferred Widths, either in the upper constraint settings to apply them to all layers; or individually for each librarry in the layer grid. For controlled impedance routing you enable the Use Impedance Profile option instead, then select the required Impedance Profile from the dropdown. When this is done, the Constraints region of the rule will change. The first thing you will notice is that the available layers region of the design rule will no longer show all signal layers in the altium designer 17 create integrated library free, it will now only show the layers enabled in the selected Impedance Profile.

The Preferred Width values and diff pair gap will update to reflect the widths integgrated gaps calculated for each layer. For single-sided nets, the routing width is defined by the Routing Width design rule.

When you choose to Use dseigner Impedance Profile, integrzted available layers and Preferred Widths are altium designer 17 create integrated library free by the selected profile.

The routing of differential pairs is controlled by the Differential Pair Routing design rule. For a differential pair, the available layers, the Preferred Width and the Preferred Gap are controlled by the selected profile.

There is a great deal of debate about corners in high-speed signal routes. While it is agreed that the electrons will not fly off when they hit a degree corner, a traditional degree corner is wider across the corner diagonal, which does change the impedance of the route. Rounded or degree corners are preferred – both are integrtaed features of the PCB editor’s interactive router – and if needed degree corners can be mitered using the Convert Selected Tracks to Chamfered Path command.

Note that this command converts the selected track segments into a single region object. So how do читать полностью know what target impedance to select?

This is normally driven by the characteristic source impedance of the logic family or technology being used. Remember, the lower the impedance the greater the current drain, the higher the impedance the more chance there will be EMI emitted, and the more susceptible that signal will be to crosstalk. This is not designner correct due to the coupling that occurs between the pair, which becomes stronger as they become closer, reducing ссылка на подробности differential impedance of the pair.

Main article: Layer Stack Management. The materials used for the layers in your board, their dimensions, and the altium designer 17 create integrated library free of and order that the layers are arranged, are all defined in the Layer Xesigner Manager.

Here cambiar el idioma del sistema operativo de windows 10 free download configure the various layers that are libraty to fabricate the final board including the copper desigher and plane layers, the dielectric layers that separate the copper, the cover layers, and the component overlay. All нажмите для деталей layers are defined in the Inyegrated Stack Manager Stackup tab.

Detailed information about the material properties that are entered in the Layer Stack Manager are included in the Layer Stack Table and also in the Layer Stack Legend placed in a Draftsman document.

You can also Save a layer stackup as a template in the Layer Stack Manager File menuand Load that template into future designs. Main article: Defining the Via Types. As mentioned in the overview section of this article, vias affect the impedance of the signal routing and are a key desifner in high-speed design. As well as the length, hole diameter, and via land area affecting the impedance that the signal sees, any unused portion of a via barrel can act as a stub, contributing to signal reflections.

These via types are all supported in Altium Designer. Back drilling of unused via barrels is also supported, these are defined in the Layer Stack Manager’s Back Drills tab Learn more about configuring the board for back drilling. All of the various types of vias that can be fabricated can be defined in the Via Types altium designer 17 create integrated library free of the Layer Stack Manager. Summarizing this study and other references, the following guidelines are given to help minimize the impact of vias:.

The design of the vias is a key ingredient in the high-speed board design process. The possible layer-to-layer via connection options are dictated by the fabrication process chosen to achieve the layer stackup, which means you must choose the fabrication and drilling process as the via style and the layer stackup is being defined.

The feature supports back drilling from both sides of the board, and back drilled sites can be easily examined in the PCB panel, with the board displayed in 3D mode. Read more about Controlled Cree Drilling. A altium designer 17 create integrated library free quality return path is essential for each high-speed signal in the design. Whenever the return path deviates and does not flow under the signal route, a loop is created and this loop results in EMI being generated, with the altium designer 17 create integrated library free integrrated directly related altium designer 17 create integrated library free the area of the loop.

The first image is a plane layer split into 3v3 and 5v0 zones; the second image is a signal layer with a 3v3 polygon and a 5v0 polygon. Net colors have been assigned and highlighting enabled. Altium designer 17 create integrated library free is general agreement that a ground plane should not be split unless there is a specific requirement for it and you understand how to define and manage it.

Instead, the components should be arranged to keep noisy components separate from quiet components, and to also cluster altiuj by the supply rail that they use. To help with the task of visually checking the return paths, you can configure the display so you can more easily examine the return path under the critical route paths.

Checking if signals travel over a split line as they traverse different voltage areas on the plane. The four highlighted integrtaed cross a split in the VCC power plane, creating a split in the return path of those signals.

Your net s will stand out, and any splits or libragy that lie in the return path, such as split lines or blowouts created by through-hole pads and vias, will be easier to see. Breaks or necks in the return path can be detected по этой ссылке the Return Path design rule.

The Return Path design rule checks for мое eset smart security 64 bit free download думаю continuous signal return path on the designated reference layer desigjer above or below the signal s targeted by the rule. The return path can be created from fills, regions, and polygon pours placed on the reference signal layer, or altkum can be a plane layer.

Http://replace.me/29352.txt return path layers are the reference layers defined in the Impedance Profile altium designer 17 create integrated library free in the Return Path design rule. These layers are checked to ensure the specified Altium designer 17 create integrated library free Gap width beyond the signal edge exists along the signal’s path.

Add a new Return Path design rule in the High Speed rule category. The return path layers are defined in the selected Impedance Profilethe path width beyond the signal edge is defined by the Minimum Gap.

So even a mid-range desktop is typically going to be more powerful and substantially less expensive than a high spec CAD laptop. By keeping the power at your desk, you can have a cheap laptop or tablet that is sufficient for client demonstrations, requirements gathering, or technical work, reducing your total costs and increasing your productivity.

Whenever the return path deviates and does not flow under the signal route, a loop is created and this loop results in EMI being generated, with the amount being directly related to the area of the loop. The first image is a plane layer split into 3v3 and 5v0 zones; the second image is a signal layer with a 3v3 polygon and a 5v0 polygon. Net colors have been assigned and highlighting enabled.

There is general agreement that a ground plane should not be split unless there is a specific requirement for it and you understand how to define and manage it. Instead, the components should be arranged to keep noisy components separate from quiet components, and to also cluster components by the supply rail that they use.

To help with the task of visually checking the return paths, you can configure the display so you can more easily examine the return path under the critical route paths. Checking if signals travel over a split line as they traverse different voltage areas on the plane. The four highlighted nets cross a split in the VCC power plane, creating a split in the return path of those signals. Your net s will stand out, and any splits or discontinuities that lie in the return path, such as split lines or blowouts created by through-hole pads and vias, will be easier to see.

Breaks or necks in the return path can be detected by the Return Path design rule. The Return Path design rule checks for a continuous signal return path on the designated reference layer s above or below the signal s targeted by the rule. The return path can be created from fills, regions, and polygon pours placed on the reference signal layer, or it can be a plane layer.

The return path layers are the reference layers defined in the Impedance Profile selected in the Return Path design rule. These layers are checked to ensure the specified Minimum Gap width beyond the signal edge exists along the signal’s path.

Add a new Return Path design rule in the High Speed rule category. The return path layers are defined in the selected Impedance Profile , the path width beyond the signal edge is defined by the Minimum Gap. The image below shows return path errors detected for the signal, NetX , with a Minimum Gap setting of 0. Doing this highlights the exact locations where the rule has failed, rather than the entire object s in violation.

To avoid detecting small errors, such as the section highlighted in the diagonal track segment in the image above, configure the PCB. The definition of differential pairs can be done during schematic capture, or they can be defined once the design has been transferred to board layout. Differential pairs are identified on the schematic by placing a Differential Pair directive on each net, or by placing one on a Blanket directive , where the Blanket directive overlays a set of enclosed differential-style Net Labels, as shown in the image below.

A Blanket can be used to configure multiple nets as differential pair members. A key requirement of managing high-speed signals on a board is to control and tune their route lengths. The delay caused by the length of the pin within the device package is supported, to learn more read about Pin Package Delay. Nets that include serial components in their path are managed by defining xSignals.

To understand how the settings of these two rules are resolved when both are present in a design, refer to the Length Tuning page. Current route lengths are displayed in the Nets mode of the PCB panel, and are updated as you route. The Routed length value will go yellow as you approach the target length, and turn red if you exceed it.

The Gauge shows the current Routed Length as a number over the top of the slider, while the slider shows the Estimated Length.

The Gauge settings are calculated from the constraints defined by the applicable rules. These commands add accordion sections to the routing, in a choice of three shapes. If there is an applicable Length rule and Matched Length rule, the length tuning tool considers both of these rules and works out the tightest set of constraints.

So if the maximum length specified by the Length rule is shorter than the longest length targeted by the Match Length rule, then the Length rule wins and its length is used during tuning.

To see which rules are being applied or to change the accordion properties during length tuning, press Tab to open the Interactive Length Tuning mode of the Properties panel, as shown below. Note the Target Length , this is the Max Limit of the strictest applicable rule settings.

Press TAB during length tuning to open the panel in Interactive Length Tuning mode, where you can select the target length mode and adjust the accordion parameters. To tune the length of a net, run the command and then click anywhere along the net’s length. Move the cursor so that it follows the path of the route, tuning accordion sections will be added as you do. Tuning sections will continue to be added until the length requirements defined by the applicable design rule s have been satisfied.

If the cursor moves outside the bounds of the tuning accordions, the accordion shapes will disappear – when the cursor is moved so that it is back within the bounds of the accordion shape, they will re-appear.

Length and Length matching rules can be applied to nets, differential pairs or xSignals. While it is not possible to derive a universal set of rules that apply to every high-speed design, it is possible to follow good design practices that will help you succeed with your high-speed design. There are a number of industry experts that deliver practical and popular training courses on high-speed design.

Use the links below to learn more, and to research specialized training options. The author gratefully acknowledges the work of the following industry experts, this article is an attempt to summarize their collective knowledge. Douglas Brooks articles. Lee W. For example, DDR routing uses a fly-by topology, where a single bus branches off to reach multiple components in the design. In another example, SPI uses a similar bus topology, but with termination applied at the load points on the bus.

Other components might use point-to-point topology to reach multiple components, which is most common when a design requires a single component communicating with multiple loads over a single IO interface. Make sure you understand the routing topology needed in your signaling standards, as well as whether those traces require impedance control.

Traces in your PCB layout are routed by simply pointing and clicking locations in the board. Along the way, copper traces will be fixed at the desired point where the user clicks the mouse, eventually spanning across the layout to the required location. Signal integrity is one area that is intimately related to PCB stackup design and routing. This simple guideline and the routing rules shown above will help prevent or reduce many signal integrity problems and will help ensure your board remains functional.

The most advanced routing tools that can help you stay in line with basic PCB routing guidelines are interactive. In other words, these tools are semi-automated, allowing you to define routes for a group of signals, and the routing tools will place traces such that they automatically obey your design rules.

In this type of routing, the design rules for your nets and groups of nets are checked automatically as you create your PCB layout. Many freeware and open source design programs force you to do everything manually, but advanced PCB design programs like Altium Designer can help you stay productive as you work to complete your PCB layout and route traces around your board.

The integrated design rules engine in Altium Designer automatically checks your routing as you place traces, allowing you to spot and eliminate errors before you finish the board.

To improve the usability of the Via mode of the Properties panel when editing a via stack in Top-Middle-Bottom or Full Stack mode, the user interface of the panel’s Via Stack section has been changed. Basic information about the via stack on different layers of the PCB design is now available for viewing and editing in tabular form.

When you click within a layer name cell, the Thermal Relief option becomes available. A custom thermal relief can be set if the Relief option is enabled.

Tuning and matching the route lengths within a specific tolerance is an essential ingredient for a high-speed design as it ensures that timing-critical signals arrive at their target pins at the same time. In this release, tools for specifying length matching requirements have been enhanced by implementing a feature for selecting an xSignal as a target for a Matched Lengths design rule when an xSignal class or all xSignals of the design is used as the rule scope.

The previous behavior used the longest xSignal of the xSignal class as a target for length matching. When an xSignal class is selected as a Matched Length design rule scope, one of its xSignals can be selected as a source target. The xSignal selected as a target will be labeled as such in the new Margin column of the xSignals mode of the PCB panel while deviation from this target length is shown in this column for other xSignals of the selected class. Deviation from the target length is shown in the new Margin column.

During interactive length tuning, the Interactive Length Tuning mode of the Properties panel provides the ability to switch between tuning relative to the selected target xSignal the new behavior or the longest net in the xSignal class scoped by the rule the previous behavior. Select a desired mode for the tuning target during interactive length tuning.

If a PCB component has its primitives locked the Primitives option in the Component mode of the Properties panel is in its state , most properties of these primitives can no longer be modified by graphical e. This will help to prevent occasional changes of component primitives that can result in incorrect assembly and fabrication outputs.

By way of an example, the Pad mode of the Properties panel is shown in the image below for a pad that is a constituent part of a PCB component that has its primitives locked. Note that all properties of the pad except for Net and Testpoint properties are dimmed and not available for editing.

Note also that the icon is shown at the far right of the pad’s Component field, which denotes that the parent component has its primitives locked, and pad properties cannot be modified.

The Pad mode of the Properties panel on the left for a pad of a PCB component that has its primitives locked on the right. Enhanced Save to Server Dialog. A hint that describes how to link an existing task to the project commit has been added to the Save to Server dialog. The “ Add task-id to connect this commit to a task “ text is displayed in the Comment field. As the hint states, add the task ID to the Comment field as it appears in the Comments and Tasks panel ; the task will be linked to the project commit that will be created after clicking OK in the dialog.

The link to the commit will be shown in the task detail pane when the task tile is selected on the Tasks page of the Altium Workspace browser interface or the Tasks view of the project’s detailed management page. Click the link to open the project’s History view with the related commit highlighted on the timeline. The link to the connected commit will be shown in the task detail pane. Hover the cursor over the image to see the History page that opens after clicking the link and the related commit highlighted on the timeline.

The speed of the simulation process has been increased when running analyses. Also, when using the Components panel for browsing large simulation model libraries, the speed to upload the content of such libraries has been improved.

Simulation models used in a project are cached now in the project, so simulation of such projects can be easily run on different machines. Any digit or number may be used as the first or last index of a repeated Sheet Symbol, including 0. Negative numbers are not allowed. The last index must always be larger than the first index.

Use this new feature to add the new class Component Class Name to set parameters for components within a blanket by means of the Parameter Set mode of the Properties panel. Associating the Component Class Name to a component or group of components will result in sending the information about the component class, its name and members to the PCB as is done currently for Net Classes. Added the ability to mark a pin as containing internal pull-up or pull-down resistors. The new graphical symbol will be displayed next to the pin as sown in the images below.

Many designers use the special string capabilities available in Altium Designer to create complex strings that display important information on the schematic sheets. Special string support has been added to Text Frames and Notes, allowing you to create complex special string definitions as a single, multi-line text object. Altium Designer supports resolving numerical calculations defined in a Text String, with support for resolving numerical calculations extended to include those defined in schematic Text Frames and Notes.

When this feature originally entered into closed beta as indicated above , the special string or formula had to be enclosed in curly brackets. The last variant that was set prior to closing a project is now remembered and will be the variant presented when the project is reopened. Previously, the base design [No Variation] was always presented when the project was reopened.

A number of improvements have been applied to the Counterholes functionality that was implemented in previous releases. If the size of the counterhole is larger than or equal to the pad size, the pad shape is removed from the corresponding side of the PCB since this pad shape will be drilled out when drilling the counterhole. Example of a removed pad shape from the top layer. Previous releases include significant improvements to the process of working with Rigid-Flex board designs in Altium Designer.

This new feature set is referred to as Rigid-Flex 2. In this release, to enable the Rigid-Flex 2. Enable the Advanced Rigid-Flex mode to configure a Rigid-Flex board; either via the Tools menu or by clicking the features button hover the cursor over the image to show this. Note that when trying to disable the Rigid-Flex 2. When the option is enabled, the rule tests the creepage distance between scoped polygons and other objects. If a polygon pour and other objects are scoped by a Creepage Distance design rule with the Apply to Polygon Pour option enabled and a Clearance design rule , both rules are considered and the tightest set of constraints is applied when pouring the polygon.

For example, if the Creepage Distance rule has a larger constraint value than the Clearance rule, this larger value will be applied. An option for accessing the Comment Export Configuration dialog has been added to the Comments and Tasks panel. Click the button at the top-right of the panel then select the Export Comments option from the menu to open the dialog and configure the comment export to a separate document.

The Remove Leading Zero option has been added to the Document Options mode of the Properties panel that allows you to automatically remove the leading zero for mil and inch values. This option is disabled by default. Default values of some additional properties of the Draftsman’s Drill Table object can now be defined on the Draftsman – Defaults page of the Preferences dialog. Default settings for some additional options of Draftsman’s Drill Table can now be defined on the Drill Symbols tab of the Preferences Draftsman – Default page.

The xDxDesigner Importer has been enhanced to allow importing an xDxDesigner project to also import defined variants of that project automatically. To import xDxDesigner project variants, the following steps should be performed:. This release brings further improvements to the Sensitivity Analysis tool. Group Deviations of Global parameters as a sensitivity parameter are now supported, and Temperature as a sensitivity parameter is also now supported.

The Global Paramete r option has been added to the Sensitivity analysis Group Deviations options; hover the cursor over the image to show where the parameters are defined. Adding cross-references to the project allows you to easily follow the connective flow of nets between the schematic sheets in a project.

In this release, the support of cross-references has been extended by adding the Jump to commands for Sheet Entry and Off Sheet Connector objects. When cross-references are enabled for sheet entries on the Options tab of the Project Options dialog , use the Sheet Entry Actions right-click menu of a sheet entry to Jump to the matching port on the child schematic sheet. Use the Jump to command to jump to the matching port.

For a flat design, when cross-references are enabled for off-sheet connectors in the Project Options dialog, use the Off Sheet Actions right-click menu of an off-sheet connector to Jump to a matching off sheet connector on a related schematic sheet. Use the Jump to command to jump to a matching off-sheet connector.

Keepout objects placed in a PCB design can now be shown in a panelized embedded board array using the PCB as a source. Enable visibility of the Keepout layer on the Layers tab of the Properties panel when an Embedded Board Array is selected in the design space. Note that this feature only provides a visual representation of the Keepout layer. This gives you the freedom to customize the color in order to distinguish the cursor from grids, etc.

Click the color box associated with the new option to open the Choose Color dialog , then select the desired new color for the cursor. To improve the usability of the Pad mode of the Properties panel when editing a pad stack in Top-Middle-Bottom or Full Stack mode, the user interface of the panel’s Pad Stack section has been changed.

Basic information about the pad stack on different layers of the PCB design is now available for viewing and editing in tabular form.

When clicking within a layer name cell, additional options become available for this layer: Corner Radius for Rectangular shape and Thermal Relief shows the current parameters of the pad’s thermal relief; custom thermal relief can be set if the Relief option is enabled.

The updated Pad Stack section of Pad properties when editing a pad stack in Top-Middle-Bottom the first image or Full Stack the second image mode with the Top layer options expanded. Upon validation of a PCB design project, the Components and Nets folders that list the project’s components and nets are displayed in the Projects panel.

To manage the visibility of these folders, the Show Components and Nets folders option has been added to the Settings pop-up of the Projects panel appears when the icon is clicked at the top of the panel and the General region of the System — Projects Panel page of the Preferences dialog. The Show Components and Nets folders option in the Projects panel setting pop-up.

The Comments panel allows you to add comments to a defined area or point in the active document of a Workspace project and assign these comments to Workspace members, essentially creating tasks for them.

To reflect that, the panel has been renamed Comments and Tasks. Also, the new Tasks only option in the panel’s filter menu allows you to display only the comments with tasks. Note that the functionality for creating and managing tasks from the Comments and Tasks panel is not supported with the Standard Subscription Plan. As such, with this level of access to Altium , this functionality is not available and the panel will be titled Comments.

Sensitivity Analysis provides a way of determining which circuit components or factors have the most influence on the output characteristics of a circuit. With this information, you can reduce the influence of negative characteristics, or alternatively, enhance the circuit performance based on positive characteristics. The result of the analysis is a table of the ranged values of sensitivities for each measurement type. Once it has been enabled, the Sensitivity properties can be configured in the Advanced Analysis Settings dialog, as shown below.

The Via Type View object has been added to Draftsman documents. The view will display in the document. Select the view to access its properties. In this release, the support for automatically creating and updating cross-references has been extended for the Sheet Entry objects.

Sheet Entries will be tagged with sheet and location coordinates of the corresponding port object on the child schematic sheet. Enable the Automatic Cross References and Sheet Entries options in project options for tagging sheet entries with cross reference values.

Cross references are enabled for sheet entries. Cross Reference values are also displayed in the Sheet Entry mode of the Properties panel , which simplifies the task of identifying the Cross Reference that is being applied to the selected Sheet Entry. Cross References can be explored in the Properties panel of the selected sheet entry. Support of cross references has also been extended in schematic PDF outputs. If an object is related to more than one connected object e. Select a list item to open the corresponding page.

In the schematic PDF output, multiple connected objects can be easily navigated using the pop-up menu. To give you greater control over the glossing process, a new Gloss And Retrace panel has been introduced for configuring options for the Route » Gloss Selected and Route » Retrace Selected commands.

This new panel can be used to set the gloss and retrace parameters that work best for the selected routing that you are currently glossing or retracing in your design.

For the following two options, you can choose between the Min , Max , or Preferred value of the corresponding rule. Choose Current to leave the existing width or gap unchanged, or type in a new value. Whenever a change is made in the panel or Preferences dialog, it is reflected in the other. The installation defaults are preset to match earlier versions. Glossing behavior during interactive routing or interactive sliding is controlled by the settings in the PCB Editor – Interactive Routing page of the Preferences dialog which can also be configured while you are working in the Interactive Routing and Interactive Sliding modes of the Properties panel.

You can now select the via type to ensure it is protected according to the IPC standard. Additionally, when a via that has the via type set to IPC in its properties is placed in a PCB design, new types of mechanical layers and component layer pairs are automatically added to the design, with corresponding shapes on these layers.

The IPC via type mechanical layers are automatically added to the design. The Top Tenting layer is shown on the design space by way of example. Changes made to PCB component designators did not previously update custom, designator-specific design rules.

They had to be updated manually. Enabling this new feature changes references in design rules when PCB component designators are: reannotated; updated by an ECO; or manually edited on the board. Because of their small physical dimensions, routing in and out of surface mount devices is often dense and complex. In previous versions of the software, if the SMD rules could not be observed, for example, the required ‚distance to corner‘ was not available; the router would fail to place any track segments as shown in the video below.

To improve the pad entry and exit behavior, the following improvements are available:. Counterholes in the laminate allow room for screw heads. Countersink and counterbore holes are two types of counterholes that allow for different types of screws.

This release introduces the ability to choose counterbore or countersink holes. The key difference between countersink and counterbore screws is the size and shape of the holes; counterbore holes are wider and more square to allow for the addition of washers.

Countersink holes create a conical hole matching the angled shape on the underside of a flat-head screw. A countersink is a cone-shaped hole cut into the laminate. It is typically used to allow the tapered head of a screw to sit flush with the top of the laminate. By comparison, a counterbore makes a flat-bottomed hole and its sides are drilled straight down.

This is usually used to fit a hex-headed cap or screw. Only one countersink or counterbore hole per pad is allowed. Use the new options in the Pad mode of the Properties panel to choose the type of counterhole desired. A dashed line appears around the pad in 2D to define the counter hole contour on the active layer as shown in the images below. The positioning of the dashed lines is different for Top Side and Bottom Side as seen in the images.

Counterholes are supported in 2D, 3D, and in Draftsman. A ‚virtual‘ BOM item is added to the project in the Projects panel if there is at least one component in the project. You can open, save or remove the BOM item. BomDoc has been saved it will become a standard project document. When a project document is removed or its UniqueID has changed, the comments for the document can become „detached“.

Those comments can still be accessed from the Comments panel’s Detached Comments collapsible region. Click on a detached comment’s tile in the panel to show the comment in the design space of the currently opened document. You can restore a comment by selecting it then clicking the mouse. This new option allows you to specify which parameter should be used as a Local Part Name rather than using ‚Comment‘ by default.

Enable the option then use the associated drop-down to select the desired parameter. A focus for this release is a number of improvements in the ability to analyze simulation measurement results. Along with additional measurement types, a number of new measurement-based features have been added. These include:. The Show on chart feature displays the measurement cursors where that measurement was calculated. Hover the cursor over the image to show a Histogram of the measurement results.

The Counter Hole View object has been added to Draftsman documents. Select the view to access and view and edit the properties. The following feature has been taken out of Open Beta and has transitioned to Public in this release:. New in Altium Designer. Using Altium Documentation.

Schematic Capture Improvements Custom Names for Multi-functional Pins This feature allows for the custom naming of multi-functional pins. Note that use of the slash character to delimit each pin function is hard-coded, so if a pin name should contain a slash but without creating custom pin names for it e. Note that the names of pins with custom names use a background color different from the component body color to distinguish such pins in the design space this will not affect the schematic printouts.

When a component placed on a schematic sheet is being updated from its source library, and pins of the component have custom naming defined on the schematic sheet only, updating will not remove the custom pin naming.

The laptop comes with a Dell UltraSharp display, likely making it the best display on this list and perhaps one of the best displays available in an engineering laptop, perfect for professionals or students that can afford it.

The slightly high resolution of x will offer you a similar pixel pitch to a Full HD display on a The starting weight of 1. Front Height: 8. Rear Height: Depth: We have looked at both ends of the spectrum with Dell so far, with the Inspiron at the lower end of price and performance and the Precision Mobile Workstation at the top end.

The Dell XPS 15 sits right in the middle. The new XPS is pretty interesting, and the display looks pretty incredible with an ultra-narrow bezel and the upgraded display option with over 4k resolution in a While you can get lower-priced options than the starting price shown above, that is the price of the cheapest pre-configured i7 based XPS 15 with 16GB of RAM. The graphics card is not incredibly exciting but is fine for the Altium Designer user. While the graphics card is not exciting, the battery is.

Suppose you can stand the extra g 0. In that case, you can have an 85Wh battery configured with the laptop which, combined with the lower power graphics and efficient 10th generation laptop processor, you can expect to have one of the best battery lives on this list. If you are on the go a lot and working away from a power connection, the XPS 15 might be the right choice for you. Height: 0. Our third Dell on the list also has a very budget-friendly price.

Unfortunately, this laptop is considerably heavier than the Inspiron, coming in at 2. The basic model only comes with GB of NVMe storage, so I would highly recommend customising the laptop during the order process to upgrade that to GB at a minimum. CAD applications can consume a huge amount of disk space, as can the files they generate.

Standard SD card 2. Headset jack 3. USB 2. Wedge lock slot 6. Power-in 7. The laptop comes with some fantastic graphics card choices. There are more differentiations between the models than just the graphics card. While many laptops on this list have GB of video RAM, the extra on the RTX models gives you that bit of extra you need for dealing with a lot of graphics data or large textures. I would have loved to have seen Windows 10 Pro as an option on this laptop too, however, with the flashy keyboard, I imagine that business users probably are not the primary market for this beast.

This laptop is only one of two on the list with a The Microsoft Surface Book is probably not what most people would expect to see in a laptop for engineering software, but it does have some interesting features. The surface book is somewhat of a hybrid between a tablet and a laptop.

The keyboard is detachable, essentially acting as a docking station with an integrated battery, keyboard and touchpad for the tablet. The battery life in the Surface Book 3 is exceptional but comes at a severe performance penalty.

The Intel Core U series processors run at just 15W, compared to the H series at 45W, that every other Intel-based laptop on this list uses. At full power usage, some reviews state the battery only lasts 3hours, whilst others say hours.

From the list above, the Dell Inspiron , or the Dell G15 has to be my top picks for a student. Both are budget conscious, and the Inspiron is the lightest laptop in the list, which is great for traveling to and from university. However, the Dell G5 15 has significantly more graphics power than the Inspiron though it comes with a substantial weight penalty.

If your course demands a more powerful laptop, or you want something a bit more rugged, then the Dell XPS 15 offers a great tradeoff between price, performance and battery. The primary competitor to the Dell XPS 15 is the MSI Prestige 15, offered at a lower price yet having only slightly lower performance whilst retaining the large battery capacity and lower weight. However, it really depends on the demands of your course and your usage. All of these laptops are within 1kg 2.

We still have some laptops with similar specifications in the list this year, so you may be able to find some fantastic deals available on previous year model laptops, or refurbished laptops if you shop around.

The needs of businesses are generally going to be different than those of students. For businesses, cost is typically less of an issue as productivity gains bring their own savings. If you struggle to get time at a single desk and are frequently on the move yet need the power of a workstation computer. For something at a lower price point, the Dell XPS 15 offers a fair tradeoff for businesses just as it does for students who can spend a little more money.

The weight is higher than I would personally prefer to have in a laptop, but you get a lot of features for that added weight – such as a larger screen, lots of battery and an incredibly powerful graphics card.

If you need to make quick revisions to models or products at a clients office and then generate a render on your laptop, the MSI GS75 would be my top choice. If you are using software that requires, or strongly prefers ISV certified hardware, then one of your only choices will be the Dell Precision Mobile Workstation series.

Suppose you need a powerful computer for engineering work and visiting client sites, and do the intensive engineering work at your desk at home or in the office. In that case, you might consider building or buying an engineering desktop computer and purchasing a cheap laptop to take on the road with you. So even a mid-range desktop is typically going to be more powerful and substantially less expensive than a high spec CAD laptop.

By keeping the power at your desk, you can have a cheap laptop or tablet that is sufficient for client demonstrations, requirements gathering, or technical work, reducing your total costs and increasing your productivity.

Altium designer 17 create integrated library free.Top 9 Best Laptops for Engineers in For Students or Professionals | Blogs | Altium

 

Parent страница Working with File-based Component Libraries. In this model, the higher-level component is modeled within the schematic symbol in a schematic library file. Altium designer 17 create integrated library free models are linked from the symbol and component parameters are added to the symbol.

All source libraries — symbol and altium designer 17 create integrated library free models — are defined within an Integrated Library Http://replace.me/6571.txt project, which is subsequently compiled into a single file — an Integrated Libraryor IntLib. This document takes a look at the various ways in which an integrated library may be created, as well as placement from and modification to such a library.

LibPkg is a type of Altium Designer project that is used to gather together the set of design documents required to produce an integrated library. These are stored across нажмите для продолжения or more schematic library files. The only document that must be added to the integrated library package is the schematic library or libraries.

Create a new integrated library package by choosing the File » New » Library command from the main menus then selecting the Integrated Library option from the File region of the New Library dialog that opens. After clicking Createthe new shell library package project will be added to the Projects panel думаю, filemaker pro advanced 17 full free сам initially will not contain any documents.

SchLib containing the components required. For each component, add the required model links and parametric information. There are two altium designer 17 create integrated library free to altium designer 17 create integrated library free a source schematic library:. With the source schematic library or libraries prepared, add to the library package using one of the following methods:.

Source SchLib added to the library package. Ckt files. With the model files defined, they now need to be made available to the library package, altium designer 17 create integrated library free that they can easily be located when required — remember, the models are referenced by or linked to the schematic components. Altium Designer has a standard system for making models available, regardless of whether you are building an integrated library package, or working on a schematic design.

There are three ways of making models available:. There are advantages to each, so choose the method that best suits your work practices. Different models also work better with different approaches too. In this case, define a search path to the folder where the simulation models are stored and add the PCB library to the library package. Collectively, these three methods of model availability form the Available File-based Libraries available to a project and can all be defined in the Available File-based Libraries dialogwhich is accessed by clicking the at the top-right of the Components panel then selecting the File-based Libraries Preferences command.

Define model availability through the Available File-based Libraries dialog. The PCB library and other model files if required can also be added to the library package directly using the Add Existing to Altium designer 17 create integrated library free commandwhich is available from the main Project menu or from the right-click menu associated with the library package’s entry in the Projects panel. Source PcbLib added to the library package. Add one or more paths as required, remembering that models are searched along these paths in order from top to bottom.

Click altium designer 17 create integrated library free Refresh List button to verify that the required model files are indeed found and adjust a path if necessary.

An example of a defined search path along which to find the required PcbLib model file. With the source libraries added to the library package and any paths to model files defined as required, the package can now be compiled to ultimately generate the integrated library.

Additionally, pin mapping errors can be checked, such as mapping instructions to pads 1 and 2 when the actual footprint contains pads A and K. Prior to running a compilation, it is prudent to browse through and set the error reporting conditions appropriately, on the Error Reporting tab of the Options for Integrated Library dialog.

It is a good idea to set error reporting options and severity levels as required, prior to compiling the library package. To proceed with compilation, use the Compile Integrated Library command either from the main Project menu or from the right-click menu associated with the library package’s entry in the Projects panel.

The compiler will check for violations and any errors or warnings found will be listed altium designer 17 create integrated library free the Messages panel. Fix any problems in the source libraries then recompile. Example errors flagged by the Compiler upon compilation of the integrated library package. It is automatically added to the Installed tab of the Available File-based Libraries dialog and the Data Management — File-based Libraries page of the Preferences dialog.

The compiled integrated library is added to the Installed tab of the Available File-based Libraries dialog. An integrated library can also be made directly from constituent project documents source schematics and PCB document. Streamlined creation of an integrated library, directly from the schematic and PCB documents in the active design project.

Related page: Working with Database Libraries. Altium Altium designer 17 create integrated library free Database Libraries are an ideal altium designer 17 create integrated library free if you want your Altium Designer components to be tightly coupled to your company database.

If the design needs to leave your company site, or if you prefer to have your designers work from secure integrated libraries, this can be readily achieved. Altium Designer provides the facility to compile увидеть больше integrated library directly from a database library: either a standard database library DbLibor a version-controlled SVN database library SVNDbLib. In this way, your CAD Librarians can still use database libraries, while your designers use regularly regenerated integrated libraries working in an ‚offline‘ fashion as it were.

Conversion is performed using the Offline Integrated Library Maker wizard. The adobe photoshop elements 10 update free is carried out on a per database table basis, with full control over which tables читать далее the database are considered. A separate integrated library will be generated for each included table. Results of the conversion process — library package altium designer 17 create integrated library free with constituent symbol and footprint model documents and the compiled IntLibs, which are also added as installed libraries.

And when placing components from such an Integrated Library, the actual links are back to the components in the Workspace. This gives you the ability to effectively use your company’s Workspace components in an offline fashion, while ensuring the design still maintains a true connection to those components in the source Workspace.

From the Content Cart dialogthe process to acquire an Перейти на источник altium designer 17 create integrated library free as follows:.

Click on the Select target server link and choose IntLib file from the menu. Altium designer 17 create integrated library free the target of the Content Cart to be an IntLib file. Specify the name, and location, for the generated IntLib file. Modify this as required through the Save As dialog — accessed by clicking the Change link.

Accept the default target folder and lightworks free for windows 10 64 bit, or change as required. Once ready, click the button to proceed with generation of the IntLib. LibPkg will be created, with source SchLib with symbols, parameters, and model links and PcbLib with footprint models files generated and added.

This is then compiled to produce the IntLib file, which is generated in the specified folder. An information dialog will confirm successful generation of the file.

Deliver the cart to the target folder, which will contain the required Integrated Library file. Placement of components from an integrated library is performed from the Components panel. Placement can be made from the active schematic document or the active PCB document. Placement can be performed in the following ways:. While a schematic library and an integrated library may contain the same component with all the same model linksthe placed components from each of these libraries will behave differently when their model information is retrieved.

Those components placed from integrated libraries will look for the original integrated library to get their models, while those components placed from schematic libraries will have no access to models stored in integrated libraries. Integrated libraries are used to place components and cannot be edited directly. To make changes to an integrated library, make modifications in the source libraries first and then recompile the library package to generate a fresh integrated library that includes those changes.

There may be occasion where the source libraries in an integrated library need to be accessed for modification, but for whatever reason, there is no access to the original source library package project by which to do so. This is where another aspect of a single, portable integrated library file, comes into play.

Although integrated libraries cannot be edited directly; they can be de-compiled back into their constituent source symbol and model libraries. In the Open Integrated Library dialog that appears, click the Extract button.

The source schematic and model libraries are extracted and saved in a new folder named after the integrated library’s filename in the folder in which the original integrated library resides. LibPkg is then created and the source schematic and PCB libraries are added to the project and presented in the Altium designer 17 create integrated library free panel.

Simulation model and sub-circuit files are not automatically added to the project. Extracting the source libraries from an integrated library — de-compiling to produce a library package project. Working with Integrated Libraries in Altium Designer. Using Altium Documentation.

Gathering model libraries into the project or locating them by search paths depends on your particular working style. If checking and editing models while preparing the integrated library package, you may want to have the model libraries right at your fingertips, and so add them to the package itself.

If continually adding model libraries to specific folders on a hard drive or network, then you may prefer to use the search paths, letting altium designer 17 create integrated library free compiler detect newly added libraries automatically.

When making a schematic library from placed components in an existing design project, all source schematic documents will be opened automatically. SearchPaths option must be enabled in the Advanced Settings dialog — accessed by clicking the Advanced button, on the System — General page of altium designer 17 create integrated library free Preferences dialog.

You will need to restart Altium Designer for the change to this setting to take effect. PcbLibit is recommended that you compile your schematic libraries in an integrated library package if only to ensure that the source components will map correctly to the target models. The currently installed ссылка на подробности can be viewed from the Data Management — File-based Libraries page of the Preferences dialog and from the Installed tab of the Available File-based Libraries dialogwhich is accessed by clicking the at the top-right of the Components panel then selecting File-based Libraries Preferences.

If you need to acquire additional components into the same IntLib, click the Add More Читать link, and choose the Select entry to access the Choose Item dialog a ‚trimmed-down‘ version of the Explorer panel. From here you can browse the source Workspace for more Items. Alternatively, choose the Add manually entry to access the Add new items dialog. This dialog allows you to paste an external list of items that you require one item per lineand which can then be searched for within the source Workspace, using a chosen search criteria GUIDItem IDNameor MPN.

By using the Place button method, multiple instances of a component can be placed since this method remains in placement mode until right-clicking or pressing Esc. The drag-and-drop method feels more immediate but is ’single-shot‘ in nature. A path to the folder altium designer 17 create integrated library free the source library and model files where applicable is automatically added on the Search Paths tab of the Options for Integrated Library dialog Project » Project Options — ensuring that any models especially.

The library package is not automatically saved. Determine where and under what name the project is to be saved — by default, the file will be жмите in the same folder as the extracted source files.

The MSI Prestige is targeted at creators – artists and software developers, but it is also well suited to engineers and CAD users for all the same reasons. The latest generation processor is not as powerful as the Intel i7 H you’ll find in other engineering laptops for students or professionals. Despite this, the processor is perfect for applications that tend to do most of their work on a single thread, such as Altium Designer or Solidworks.

Given the price point of this laptop, the performance is quite acceptable. This still makes it a great option for Altium Designer work, even with complex boards that have many 3D models, you might feel a bit limited for MCAD applications, video editing or GPU based simulation workloads.

If you love being able to spec out every last feature of your computer, Dell is the master of configurable laptops. The CPUs and graphics are all the latest and greatest for this laptop. The precision series laptops are all built specifically for engineering applications, and the series has been around for a long time.

The ones I have owned in the past have been solidly built and designed for use. Being that these are priced for business, you can typically obtain a lower price by talking to a sales rep, and substantially lower price if your company is already a big Dell user. Dell has regular sales which can offer significant discounts too. The price of a Precision Mobile Workstation is likely going to put it out of reach of students; however, for the professional engineer, the performance will offer a fast return on investment in hours saved and increased productivity.

As an advantage for business users, Dell also offer a month on-site warranty, at least in the USA. Finally, Precision workstations are ISV certified, meaning professional software packages that like to run on certified hardware will be very happy.

The laptop comes with a Dell UltraSharp display, likely making it the best display on this list and perhaps one of the best displays available in an engineering laptop, perfect for professionals or students that can afford it.

The slightly high resolution of x will offer you a similar pixel pitch to a Full HD display on a The starting weight of 1. Front Height: 8. Rear Height: Depth: We have looked at both ends of the spectrum with Dell so far, with the Inspiron at the lower end of price and performance and the Precision Mobile Workstation at the top end.

The Dell XPS 15 sits right in the middle. The new XPS is pretty interesting, and the display looks pretty incredible with an ultra-narrow bezel and the upgraded display option with over 4k resolution in a While you can get lower-priced options than the starting price shown above, that is the price of the cheapest pre-configured i7 based XPS 15 with 16GB of RAM.

The graphics card is not incredibly exciting but is fine for the Altium Designer user. While the graphics card is not exciting, the battery is. Suppose you can stand the extra g 0. In that case, you can have an 85Wh battery configured with the laptop which, combined with the lower power graphics and efficient 10th generation laptop processor, you can expect to have one of the best battery lives on this list.

If you are on the go a lot and working away from a power connection, the XPS 15 might be the right choice for you. Height: 0. Our third Dell on the list also has a very budget-friendly price. Unfortunately, this laptop is considerably heavier than the Inspiron, coming in at 2. The basic model only comes with GB of NVMe storage, so I would highly recommend customising the laptop during the order process to upgrade that to GB at a minimum.

CAD applications can consume a huge amount of disk space, as can the files they generate. Standard SD card 2. Headset jack 3. USB 2. Wedge lock slot 6. Power-in 7. The laptop comes with some fantastic graphics card choices. There are more differentiations between the models than just the graphics card. While many laptops on this list have GB of video RAM, the extra on the RTX models gives you that bit of extra you need for dealing with a lot of graphics data or large textures.

I would have loved to have seen Windows 10 Pro as an option on this laptop too, however, with the flashy keyboard, I imagine that business users probably are not the primary market for this beast.

This laptop is only one of two on the list with a The Microsoft Surface Book is probably not what most people would expect to see in a laptop for engineering software, but it does have some interesting features. The surface book is somewhat of a hybrid between a tablet and a laptop. The keyboard is detachable, essentially acting as a docking station with an integrated battery, keyboard and touchpad for the tablet. The battery life in the Surface Book 3 is exceptional but comes at a severe performance penalty.

The Intel Core U series processors run at just 15W, compared to the H series at 45W, that every other Intel-based laptop on this list uses. At full power usage, some reviews state the battery only lasts 3hours, whilst others say hours. From the list above, the Dell Inspiron , or the Dell G15 has to be my top picks for a student.

Both are budget conscious, and the Inspiron is the lightest laptop in the list, which is great for traveling to and from university. However, the Dell G5 15 has significantly more graphics power than the Inspiron though it comes with a substantial weight penalty.

If your course demands a more powerful laptop, or you want something a bit more rugged, then the Dell XPS 15 offers a great tradeoff between price, performance and battery. The primary competitor to the Dell XPS 15 is the MSI Prestige 15, offered at a lower price yet having only slightly lower performance whilst retaining the large battery capacity and lower weight.

However, it really depends on the demands of your course and your usage. All of these laptops are within 1kg 2. We still have some laptops with similar specifications in the list this year, so you may be able to find some fantastic deals available on previous year model laptops, or refurbished laptops if you shop around. The needs of businesses are generally going to be different than those of students.

For businesses, cost is typically less of an issue as productivity gains bring their own savings. If you struggle to get time at a single desk and are frequently on the move yet need the power of a workstation computer. For something at a lower price point, the Dell XPS 15 offers a fair tradeoff for businesses just as it does for students who can spend a little more money.

The weight is higher than I would personally prefer to have in a laptop, but you get a lot of features for that added weight – such as a larger screen, lots of battery and an incredibly powerful graphics card. If you need to make quick revisions to models or products at a clients office and then generate a render on your laptop, the MSI GS75 would be my top choice. If you are using software that requires, or strongly prefers ISV certified hardware, then one of your only choices will be the Dell Precision Mobile Workstation series.

Suppose you need a powerful computer for engineering work and visiting client sites, and do the intensive engineering work at your desk at home or in the office.

In that case, you might consider building or buying an engineering desktop computer and purchasing a cheap laptop to take on the road with you. So even a mid-range desktop is typically going to be more powerful and substantially less expensive than a high spec CAD laptop.

By keeping the power at your desk, you can have a cheap laptop or tablet that is sufficient for client demonstrations, requirements gathering, or technical work, reducing your total costs and increasing your productivity.

Best Laptop for Engineering Software: Requirements If you need the best laptop for engineering software and you work at a professional level, I expect that you need a computer that can travel a lot between home and office or between the office and sites. Relatively lightweight. Large enough screen to use. That trace has an impedance, which is referred to as the characteristic impedance Zo.

The best way to manage the impact of these additional circuit elements is to design the trace routing so that the characteristic impedance is consistent over the length – a technique called controlled impedance routing. The Simbeor impedance calculator calculates the width s required to achieve the specified impedance. In an ideal situation, all of the energy that comes out of a component output pin would be coupled into the connected track on the PCB, flow through the PCB routing to the load input pin at the other end, and be absorbed by that load.

If all the energy is not absorbed by the load then the leftover energy can be reflected back into the PCB routing, flowing to the source output pin. This reflected energy can interact with the original signal, adding to and subtracting from it depending on the polarity of the energy , resulting in ringing. If the ringing is large enough, it will affect the integrity of the signal, resulting in unpredictable, erroneous circuit behavior.

So how do you know if this might occur? If the source pin is able to complete its edge transition before the signal reaches the load pin, the conditions exist for your design to be impacted by reflected energy. If the source pin has a 1 nSec rise time, a route longer than. If your devices have this sort of rise time and you know you will have routing of this sort of length, then you might end up with signal integrity issues on the PCB.

The speed at which the electrical energy can travel along the route is known as the propagation velocity, where:.

How do you avoid the situation where there is energy being reflected back and forth between the source and the load? You avoid it by matching the impedances. Impedance matching ensures that all the energy is coupled from the source into the routing, and then from the routing into the load.

Routing the board with regard to the impedance is referred to as controlled impedance routing or another way of saying it is that a board where impedances have been managed is called a controlled impedance PCB.

There are two distinct elements to achieving impedance matching: the first is matching the components; the second is routing the board to give the required impedance. You cannot achieve a controlled impedance PCB with routing alone. First, you must check, and if necessary, match the impedances of the components. Ideally, you want to detect nets that could have potential signal integrity issues during the design capture phase so that any additional termination components can be included before the board design process starts.

Since output pins are low impedance and input pins are high impedance, it is likely that you will need to add termination components to the design to achieve impedance matching. You can perform a signal integrity analysis on your design at the schematic capture stage. When you run the Tools » Signal Integrity command the Errors or Warnings dialog will often appear, indicating that not all components have signal integrity models assigned.

The Signal Integrity analysis engine will automatically select default models based on the component designators, click Continue to use the defaults or Model Assignments to examine and change the models.

The Signal Integrity analysis engine will use defaults for the required impedance and average track length. It will also use default values for the signal stimulus the properties of the theoretical signal that is injected.

These defaults can be configured once the Signal Integrity panel has opened, via the panel’s Menu button » Setup Options command. Note that the Signal Integrity analysis engine requires power planes for the reference planes, it is not able to use a signal layer covered by a polygon. The Signal Integrity analysis engine installs as a System Extension. If it is not currently installed, click the Configure button to install it. When the Tools » Signal Integrity command is run the design is analyzed, any potential problem nets are identified in the Signal Integrity panel, as shown below.

Testing the design for potential signal integrity issues during design capture. From the panel, you can perform a reflection analysis on a selected net or nets. On the left is the analysis results for all nets in the design, select a net and click the button or double-click a net name to transfer that net to the Net field on the right of the panel, where you can perform a detailed analysis of that net, including:. The panel allows you to experiment with possible termination configurations and values.

Note that the Termination region of the Signal Integrity panel shown in the image above has the Serial Res option enabled. The section of the panel below that shows a series termination resistor.

This is where you define the minimum and maximum theoretical series termination resistance values that will be used for the reflection analysis disable the Suggest checkbox to enter your own values. The images below show two graphs of the results at the input pin of the net selected in the previous panel image. The first graph is the input pin in the net without termination; the second graph shows six sweeps, one for the original unterminated net, then five sweeps with the theoretical series termination resistance included at the source pin.

The five passes first pass at 20 ohms, last pass at 60 ohms are listed on the right-hand side of the graph. Clicking on each label highlights that result and displays the theoretical termination resistance value at the bottom right. For this net, a series termination resistance of 40 ohms would produce the graph selected in the image on the right.

The graph on the left shows the reflection analysis of a net with potential signal integrity issues; the graph on the right is the same net with a theoretical series termination resistor of approximately 40 ohms added. To hide a floating panel, press F4 when the panel is active the caption bar is colored. Press F4 to restore the display of the panel. The second part of achieving a controlled impedance PCB is to route the board so that the tracks are a defined impedance.

There are a number of factors that influence the impedance of your signal routing, including the dimensions of the routes and the properties of the materials used to fabricate the PCB. Simbeor’s model accuracy is validated through the use of advanced algorithms for 3D full wave analysis, benchmarking, and experimental validation. The Simbeor engine supports all modern board structures and materials. The Simberian site also includes an extensive library of application notes and papers published by Simberian’s principal developer, Yuriy Shlepnev, as well as papers written in collaboration with other leading industry and academic researchers.

Simbeor SFS is an advanced quasi-static 2D field solver based on Method of Moments, which has been validated by convergence, comparisons, and measurements. The solver meshes dielectric and conductor boundaries and solves corresponding equations to build frequency-dependent RLGC matrices for the Telegraph equations. Simbeor SFS is not a full-wave solver as this is not needed to evaluate the impedance, delay, or attenuation in PCB interconnects, because of the quasi-TEM nature of the waves propagating there.

Such waves can be accurately simulated with RLGC parameters extracted with a quasi-static 2D field solver. A unique property of the Simbeor SFS solver is that it supports conductor roughness models. Note that it does not support a multi-layered conductor model plating , and the roughness is common for all conductors.

The solver is quasi-static because the solution does not include the high-frequency dispersion that takes place in microstrip lines higher concentration of fields in a dielectric with higher dielectric constant at high frequencies. Controlled Impedance routing is all about configuring the dimensions of the routes and the properties of the board materials to deliver a specific impedance. The Layer Stack Manager opens in a document editor, in the same way as a schematic sheet, the PCB, and other document types do.

The trace width required to deliver a specific impedance is calculated as part of the impedance profile, configured in the Impedance tab of the Layer Stack Manager. When these are correctly configured, the impedance calculator has sufficient information to calculate the:. To improve calculation speeds, impedance profiles are calculated in separate threads when available. The calculated values are displayed in the Transmission Line section of the Properties panel , when the Impedance tab is selected in the Layer Stack Manager , as shown below.

Main article: Defining the Layer Stack. The copper and dielectric fabrication layers are configured on the Stackup tab of the Layer Stack Manager. A fundamental requirement for controlling the impedance is to include a signal return path below each signal path. The Simbeor SI engine supports both plane layers, and signal layers covered by a polygon. These return-path layers should be distributed through the board stackup. Ideally, they are arranged so that there is at least one return-path layer adjacent to each signal layer that is carrying controlled impedance routing.

The adjacent return-path layer provides the signal return path, and for reasons that will not be covered here, does so regardless of the DC voltage distributed by that plane.

The return path current flowing through the plane will attempt to follow the same physical path as the route on the signal layer, so it is important to avoid introducing discontinuities, such as a split or cutout in the return-path layer underneath any critical signal routing. As well as selecting a suitable order for signal and plane layers, you also need to define the material properties of each layer, including:.

These values, and the routing width, all contribute to the final impedance. Achieving the required impedance then becomes a process of tuning all these values. Keep in mind that possible copper and dielectric thickness values may also be limited, determined by the materials available from your PCB fabricator. To configure the layer stack for controlled impedance routing, switch to the Layer Stack Manager’s Impedance tab where you can add and configure an impedance profile.

From the target impedance and target tolerance, the software calculates the Trace Width. It is not uncommon that the calculated trace width will be a value that cannot be ordered, for example 0. The fabricator will advise what material thicknesses are available and what precision they can achieve for trace widths. Then it becomes a process of starting at the desired values, then testing the impact on the calculated impedance values when the dimensions are adjusted to what is available.

To support this process of testing and tuning the settings, the impedance calculators support forward and reverse impedance calculations. The default mode is forward enter the impedance, the software calculates the width.

The icon indicates the calculated variable. To reverse the calculation and explore different trace widths for the selected layer, type in the new Width W1 value and press Enter on the keyboard. The calculated values will update to reflect the impact of changing to that width.

Click the button to return the calculator to forward calculation mode. Entering a new value into Width W2 will change the Etch value. To explore the differential pair transmission line results, nominate the calculated variable – either the Trace Width or Trace Gap – by clicking the appropriate button. Edit the other variable to change the Target Impedance , or alternatively change the Target Impedance to explore the impact on the other variable.

The signal traces on a PCB are fabricated by etching away unwanted copper. Because the etchant starts etching away the copper at the surface, this copper spends more time in contact with the etchant. The result is the finished edges of the trace will have a slope, reducing the cross-sectional area of the finished trace, as shown in the image below.

Hover the cursor over the? This gives the following formula:. The downside of this approach is that to specify no over-etching meaning the trace edges are vertical , you would have to enter a value of inf infinite for the etch factor.

To simplify specifying the amount of etch, the formula has been inverted so a value of 0 zero can be entered to indicate there is no over-etching. Another fabrication detail that contributes to the etch factor is the orientation of the copper. PCB traces are formed by etching away unwanted copper from a continuous sheet of copper laminated onto a dielectric substrate. The copper orientation defines the direction the copper projects away from that substrate.

You can also think of it as the direction the copper is etched from, either above or below. The Copper Orientation can be edited in the Properties panel: in the Transmission line section Impedance tab active , or in the Layer section Stackup tab active. It can also be edited in the Layer Stack Manager grid, if the Copper Orientation column is currently being displayed in the Grid.

Copper layers also include an Orientation option. This field defines on which side of that copper layer the components are mounted on.

The following features have been taken out of Open Beta and have transitioned to Public in this release:. When this and the Jump to Results options are enabled, all found elements will be zoomed while other elements are dimmed according to the settings on the System — Navigation page of the Preferences dialog. To give you more flexibility, differential pairs can now be defined using custom suffixes in the Diff Pairs region of the Project Options – Options dialog.

Custom suffixes cannot be added if only one suffix of the pair is defined or if any of the suffixes are used in another pair of custom suffixes.

The final goal of each PCB design is to get a correct and reliable set of assembly and fabrication outputs, and one purpose of any design tool is to provide a user with tools to find and resolve the issues that could arise during the design process before the design goes to production. For example, PCB components could have degrees rotation value in previous versions of Altium Designer, but this situation is not allowed anymore in the current versions — the software will set such components to 0 degrees.

To help you in detecting and resolving such issues, and some other issues that can arise under certain conditions, the concept of PCB Health Checks has been introduced. These checks allow you to discover common issues in the PCB design, fix them, and avoid potential problems during the next stages of the design and manufacturing process.

The list of available PCB Health checks will grow up moving forward. The Board mode of the Properties panel available when no object is selected in the active PCB document has the new Health Check tab that enables you to configure, perform, and explore the results of the PCB Health Check.

Recommendations for fixing the issues of a specific type can also be found on this tab of the panel. The new Health Check tab of the Properties panel is in the Board mode. This button allows you to control visibility for the board shapes of the PCBs that are constituents of the selected board array. Use the Board Shape button to control the visibility of the board shape.

All copper layer objects with a net assignment of No Net will be checked. To run the check, click Tools » Design Rule Check.

 

Altium designer 17 create integrated library free

 
Jun 09,  · Parent page: Laying Out Your PCB High-Speed Design in Altium Designer. High-speed printed circuit board design is a process of balancing the circuit design requirements, device technologies, and fabrication materials and methodologies, to deliver a PCB that can transfer signals between the components, with integrity. Jan 11,  · The logical place to make a change is at the source. The nature of this source depends on how the component was placed: From an Integrated Library – the source libraries are extracted, the change is made, and the integrated library package is compiled to generate the revised integrated library.; From a Database Library – for a parameter or a symbol/model . Include a components library so users can easily implement high-quality PCB footprints. Altium Designer is the most comprehensive, modern, end-to-end PCB design software and the number one choice among engineers and designers worldwide. Altium CircuitMaker is the best free-to-use schematic and PCB design tool for the Open Source. May 11,  · New material can added to the library when a specific material category is selected in the tree. Materials defined in an external material library can be loaded (Load button), and user-defined material that has been added in the Altium Material Library dialog can also be saved to a user-library (Save button). Only user-defined material is saved.

The logical place to make a change is at the source. The nature of this source depends on how the component was placed:. The symbol and model changes are made in the source libraries. For parameters, changes are made in the database. Once changes are made, they need to be pushed across to the design. Altium provides a variety of update tools that allow you to quickly and efficiently pass component changes to your Altium Designer components.

This document details those tools – tools that enable you to always retain synchronicity between your component source and the placed instances of those components. In the context of this tool, the term ‚Altium Designer component‘ is used to describe a component instance placed on a schematic sheet or a component in a source schematic library.

Altium Designer provides a tool for updating the parameters of Altium Designer components with information stored in an external database. The components must be linked to the corresponding component records in the external database for update to be made possible.

Linkage is performed through the use of an intermediary linking file, which can be one of the following:. DBLink file is used to provide the linking from library components to component records in the external database. Updates are performed from a schematic document using the Tools » Update Parameters From Database command available from the main menus.

Launching this command will open the Update Parameters From Database dialog. Use this dialog to choose which schematic documents and component types you want to include in the update. After defining the scope of the update, click OK. The external database will be queried for matching components. If there are parameter differences between the Altium Designer components and the matching records in the database, the Select Parameter Changes dialog opens.

This dialog lists all parameters that exist in the database records for linked Altium Designer components falling under the scope of the update. Any parameters that are defined for an Altium Designer component but are not a field in a database table will not appear listed. For example, you may have placed a component directly from a database using the database library feature then added one or more parameters after placement.

Only those parameters that are mapped between the external database and the placed component instance are listed. Parameter mapping is performed on the Field Mappings tab of the intermediary link file. Parameter differences are distinguished by the use of a unique inserted in the relevant cell. For example, a blue triangle in the corner of a cell means that a difference has been detected between the value of a parameter in the Altium Designer component and the same parameter in the linked database record.

There will be a full listing of all available cell states in the Select Parameter Changes dialog later in this document in the Parameter Update States section. The controls provided in the Select Parameter Changes dialog allow you to fully control which updates to proceed with and which to reject. You can reject updates to all parameters for a selected component or for specific parameters of that component.

To reject a proposed update for a specific parameter, select the relevant cell and click the Reject Selected button. To reinstate the update, click the Update Selected button. Use the Engineering Change Order dialog that opens to validate and then execute the updates accordingly. If you realize there is an update you really do not want to proceed with, disable the applicable change order entry. Altium Designer provides a tool for updating placed components on a schematic sheet with modified information from a source library.

The update feature passes changes to parameters, symbol and model references in the external database, as well as graphical modifications made in referenced symbol and model libraries. The update feature allows you to pass changes to parameters, as well as model and graphical information. Updates are performed from a schematic document using the Update From Libraries command available from the main Tools menu. Launching this command will open the Update From Library dialog.

The first page of the dialog deals with the scope of the update – which source schematic documents are to be included in the update and the specific component types contained thereon. The Schematic Sheets region of the dialog will load all possible schematic documents to which the update can be applied. This can be either a single, free schematic document, or all schematic sheets within the active project. Enable those documents whose components you want to be considered in the update.

Each component is listed in terms of:. Inclusion of components in the list is in accordance with the options available at the bottom left of the page. Use the Show field to determine the types of components included in the update.

By default, All Components is selected, but you can choose to update only:. All component types are initially enabled for inclusion in the update. Disable any that you definitely do not want to update. Alternatively, select the exact components that you want to update – directly on the schematic sheet s – prior to entering the dialog.

Then enable the Selected Parts Only option. Only those components in your selection will appear listed. The main thing to remember is that you are always in full control over what gets included in the update. The Settings region of the page is where you can define the default level of update required. The default update actions you define here will be applied to all component instances of the enabled component types.

The simplest form of update is to fully replace the components on the schematic sheet s with those defined in the source library. Graphical attributes, parameters and model links are all updated directly with the information that exists in the source library. Remember that if the source library is a DBLib or SVNDBLib, the parameter and model link information is derived from the corresponding component records in the external database, while the graphical attribute changes will come from the referenced symbol libraries.

Full replacement is enabled by default. Should you want a little more control over what is updated, change to replace Selected Attributes of Symbols on Sheet. Definitions on the first page of the Update From Library dialog and the Library Update Settings dialog are persistent. They are stored in the project file upon saving. For parameter and model update actions, still further control is afforded through the Library Update Settings dialog. Access this dialog by clicking the Advanced button.

Not only can you define the default, global update actions for parameters and models using this dialog, but also control which specific parameters and models are included in the update. After defining the scope of the update as required, and the default actions to be carried out, you could click Finish , then review and execute the changes to be implemented in the subsequent Engineering Change Order that is generated.

Should you want to further refine the update on a per-component basis, prior to generating the ECO, click Next to access the second page of the dialog, detailed in the next section. Definitions on the second page of the Update From Library dialog are not persistent. They will be lost if you go back to the first page or close the dialog. The second page of the Update From Library dialog presents you with a detailed grid, listing all components instances involved in the intended update process.

The previous page of the dialog allowed you to specify, at a coarse level, which physical component types get included in the update. This page allows you to fine-tune exactly which component instances of those types get updated. For each component, the entry for the source library component will initially be that used to place the component instance in the first place. This information is taken from the Library Link region of the placed component’s Properties panel. Typically, the update will involve passing on changes made to the original physical component in the source library, to the placed instance s of that same physical component on the schematic sheet s.

There may be occasion where you want to change the physical component that is placed in the design altogether. This can be readily specified as part of the update.

You can specify an alternate component for a component instance by directly editing the corresponding Physical Component field in the Library Components region.

Update in this case will not be possible, for that component instance. You cannot search for database components along a specified search path. Alternatively, select a component instance in the grid then click the Choose Component button.

The Browse Libraries dialog appears, from where you can browse for the required replacement component in any of the currently Available Libraries for the project. The dialog also provides a search facility, which can be used to search for a component within the Available Libraries or along any nominated search path. When a valid component is chosen, the relevant information for the chosen component will be entered into the Library Components region of the page, overwriting the original source library component.

If you want to revert to the original source library – keeping the original physical component – select the component instance in the grid then click the Return Selected to Default button.

Individual parameter-level changes for a component instance will be shown only if the Full Replace option is disabled and the Parameters option is enabled in the Actions region of the page. If you want to browse individual parameter changes proposed by the update, click the Parameter Changes button. The Select Parameter Changes dialog will open, summarizing the parameter changes for those component instances with a parameter update action enabled.

In the illustration below, notice that component instances C1, C3, C7, and C10 have their parameter update action disabled, and therefore, do not appear in the dialog.

As with the Update Parameters From Database tool, the dialog will list all mapped parameters for those component instances linked to an external database. In addition, all parameters found in the placed component instances involved in the parameter update will also be listed. This is a key difference when accessing the Select Parameter Changes dialog between these two update tools.

Again, the dialog shows proposed changes to be made in order to bring the parameters of the placed components back into sync with those for the components in the relevant source library or database.

The proposed updates are in accordance with the update actions defined in:. Parameter differences are highlighted by the use of a unique icon inserted in the relevant cell. See the next section Parameter Update States for a full listing of all possible cell states.

Use the available controls in the dialog buttons or right-click menu to determine with which parameter changes to proceed and which to reject, giving you the power to override the default update conditions at the individual parameter-level. Remember that rejecting a proposed update in a cell means you do not want to have any changes made to that parameter for that particular component instance on the schematic sheet. The following table lists the possible cell states.

The Update From Libraries command explained in the previous section is used solely to update placed components on schematic sheets. Although models can be included as part of that update, it is the model linking that is being considered and not the actual graphical attributes of the linked model.

Altium designer 17 create integrated library free year ago, I wrote an article about buying a laptop for engineering software. Over the past year, many CAD spec laptop series have taken a great leap forwards as new models have come out.

The majority of options considered for the list last year were running 7th generation processors, and therefore got ruled out of consideration entirely. Most of the laptops that were deeigner had 8th generation Intel processors, and there were no AMD processors in the list at all.

Fred year, Altium designer 17 create integrated library free also wrote a guide to building an engineering desktop computer, this year that has also been updated with the latest advancements.

You get a lot more performance per dollar compared to altium designer 17 create integrated library free laptop you can purchase. This year, I also have an article looking at pre-built engineering computers you can buy ready to run. If you need the best laptop for engineering software and you work at a professional level, I expect that you need a computer that can travel a lot between home and office or between the office and sites.

This travel requirement rules out having a bulky device to lug around, как сообщается здесь you still altium designer 17 create integrated library free the performance and capabilities to do real work away from your desk.

I altium designer 17 create integrated library free 26 potential engineering laptops for this article and compared designee specifications. This comparison whittled the list down to 9 laptops that are what I would recommend purely from their specifications, and in some cases, pricing. This list might http://replace.me/20950.txt have the highest performance laptops for engineering software, but it does have a great mix of portability, performance, and price.

In general, a laptop for engineering software inwhether for engineering students or a business, should have the following specifications to ensure it will last through an entire engineering degree or a 3-year depreciation for business users:.

The Quadro lineup in mid-priced laptops offers very little value for money, even if it does make some engineering applications think you have a better graphics card. The performance will still be superior with a gaming card running Studio drivers.

If you feel the need for a Quadro card, or you have been advised to get one, stick to the Quadro RTXwhich offers decent performance. Prices shown for the laptops are altium designer 17 create integrated library free of the price at the time of writing and may vary depending on the sale region, specials and changes by the manufacturer. Pricing can also vary wildly depending on the configuration, as can performance. In that case, you altium designer 17 create integrated library free still get a laptop that is suitable for most CAD work, although its lower performance is going to be noticeable in complex simulations, large 3D modelsor PCBs with hundreds altium designer 17 create integrated library free components.

This graphics card is absolutely fine for Altium Designer, which does not tend to stress a graphics card. You might find it a little odd, but I do like that this laptop has a built-in SD card reader – not all do. For a lightweight, low-cost laptop, the Inspiron offers good value for money; however, is lacking in performance compared to the other options in this list.

Height: I prefer a slightly larger laptop screen myself. However, a smaller form factor certainly has appeal to many users, especially for students that value portability. For multi-threaded applications, this could offer you an advantage. The 76Wh battery is respectable and should give you a decent run time when away from power.

Users have stated that the laptop can get very hot when being used heavily, so probably not a great choice if you want to have it sitting on читать больше lap. Many reviews say the fans are on all the time, even when doing itegrated tasks, the noise of which could be annoying to some users. If you know me, then you know I love plenty of USB ports on ddsigner my altium designer 17 create integrated library free.

Width: Last year I was desperately waiting altiim this laptop to come out before publishing, but the laptop got delayed and was not altium designer 17 create integrated library free before the article came out. If this had been released last year inegrated would altium designer 17 create integrated library free been my top pick, this year, as with last year the Lenovo ThinkPad X1 Extreme is still a great contender, however, is once привожу ссылку a generation behind the latest and greatest CPU.

There are other laptops on this list which have similar or better specifications for half the price. That being altium designer 17 create integrated library free, the ThinkPad Extreme lineup has a reputation for being very durable and well built. The MSI Prestige is targeted at creators – artists and software developers, but it is also well suited to engineers and CAD users for all the same reasons.

The latest generation processor is not as powerful as the Intel i7 H you’ll find in other engineering laptops fred students or professionals. Despite this, the processor is perfect for applications that tend to do most of their work on a single thread, such as Altium Designer or Solidworks.

Given the price point of this laptop, the performance is quite acceptable. This still makes it a great option for Altium Designer work, even with complex boards that have many 3D models, you might feel a bit limited altium designer 17 create integrated library free MCAD applications, video editing or GPU based simulation workloads.

If you love being able to spec out every last feature of your основываясь на этих данных, Dell is the master of configurable laptops. The CPUs inetgrated graphics are all the latest and greatest for this laptop. The precision intebrated laptops are all built specifically for engineering applications, and the series has been around for a long time. The ones I have owned in the past have altium designer 17 create integrated library free solidly built and designed for use.

Being that these are priced for business, you can typically obtain a lower price by talking to a sales rep, and substantially lower price if your company is already a big Dell user.

Dell has regular sales which can offer significant discounts too. Intgrated price of a Precision Mobile Workstation is likely going to put it out of reach of students; however, for the professional engineer, the performance will offer a fast return on investment in hours saved and increased productivity. As an advantage for business users, Dell also offer a month on-site warranty, at least in the USA. Finally, Precision workstations are ISV certified, meaning professional software packages that like to run on certified hardware will be very happy.

The laptop comes with a Dell UltraSharp display, likely making it the best display on this list and perhaps one of the best displays available in an engineering laptop, perfect for professionals or students that can afford it. The по этому адресу high resolution of x will offer you a similar pixel pitch to a Full HD display on a The starting weight of 1.

Front Height: 8. Rear Height: Depth: We have looked at both ends of the spectrum with Dell so far, with the Inspiron at the lower end of price and performance and the Precision Mobile Workstation at the top end. The Dell XPS 15 sits right in the middle. The new XPS is pretty interesting, and the display looks pretty incredible with an ultra-narrow bezel and the upgraded взято отсюда option with over 4k resolution in a While you can get lower-priced options than the starting price shown above, that is the price of the cheapest pre-configured i7 based XPS 15 with 16GB of RAM.

The graphics card is not incredibly exciting but is fine for the Altium Designer user. While the graphics card is not exciting, the battery is. Suppose you can stand the extra g 0. In that case, you can have an 85Wh battery configured with the laptop which, combined with the lower power graphics and efficient 10th generation laptop processor, you can expect to have one of the best battery lives on this list.

If you are on the go a lot and working away from a power connection, the XPS 15 might be the right choice for you. Height: 0. Our third Dell on the list also has a very budget-friendly price. Unfortunately, this laptop is considerably heavier than the Inspiron, coming in at 2. The basic model only comes with Ссылка на подробности of NVMe storage, so I would highly recommend customising the laptop during the order process to upgrade that to GB at a minimum.

CAD applications can consume a huge amount of disk space, as can the files they generate. Standard SD card 2. Headset jack 3. USB 2. Wedge lock slot 6. Power-in 7. The laptop comes with some fantastic graphics card choices. There are more differentiations between the models than just the graphics card. While many laptops on this list have GB of video RAM, the extra on the RTX models gives you that bit of extra you need for dealing with a lot of graphics data or large textures.

I would have loved to have seen Windows 10 Pro as an option on this laptop too, however, with the flashy keyboard, I imagine that business users probably are not the primary market for this beast. This laptop is only one of two on the list with a The Microsoft Surface Book is probably not what most people would expect to see in a laptop for engineering software, but it does have some interesting features.

Integratec surface book is somewhat of a hybrid between a tablet and a laptop. The altium designer 17 create integrated library free is detachable, essentially acting as a docking station with an integrated battery, keyboard and touchpad for the tablet. The battery life in the Surface Book 3 is exceptional but comes at a severe performance penalty.

The Intel Core U series processors run at just 15W, compared to the H series at 45W, that every other Intel-based laptop on this list frwe. At full power usage, some reviews state the battery only lasts 3hours, whilst others say hours.

From the list altium designer 17 create integrated library free, the Dell Inspironor the Dell G15 has to be my top picks for a student. Both are budget conscious, altium designer 17 create integrated library free the Inspiron is the lightest laptop in the list, which is great for traveling to and from university. However, the Dell G5 15 has significantly more graphics power than the Inspiron though it comes with a substantial weight penalty.

If your course demands a more powerful laptop, or you want something a bit more rugged, then the Dell XPS 15 offers a great tradeoff between price, performance dwsigner battery. The primary competitor to the Dell XPS 15 is windows 10 recovery mode free download MSI Prestige 15, offered at a lower price yet having only slightly lower performance whilst retaining the large battery capacity and lower weight.

However, it really depends on the demands of your course and your usage. All of these laptops are within 1kg 2. We still have some laptops with similar specifications in the list this year, so you may be able to find libraryy fantastic deals available on previous year model laptops, or refurbished laptops if you shop around. The needs of businesses are generally designed to be different than those of desigenr. For businesses, cost is typically less of an issue as productivity gains bring their own libarry.

If you struggle to get time at a single desk vesigner are frequently on the move yet need the power of a workstation computer. For something at a lower price point, the Dell XPS 15 offers a fair tradeoff for businesses just as it does for students who can spend a little more money. The weight is higher than I would personally prefer to have in a laptop, but fdee get a lot of features for that added weight – such as a larger screen, lots of battery and an incredibly powerful graphics card.

If you need to make quick revisions to models or products at a clients office and then generate a render on your laptop, the MSI GS75 would be my top choice.

After importing the board and arranging components on the board, it would seem a relatively easy matter to start connecting components with copper. Traces on a PCB can carry very specific design requirements that are meant to ensure signal integrity during routing. So what is PCB routing? All PCBs need to have copper that connects components on the surface layer or internal layers, known as traces. As a designer, your job is to find a balance in all of these areas and determine which of the points in the above list are most important for different nets.

For example, high speed designs rely on controlled impedance with differential pairs, while high current DC designs need to have wide traces that do not necessarily have specific impedance. If your design is not running at high speeds, it is not dense enough to create problems with crosstalk, and your traces need to carry low current, then you are typically free to select a trace width that easily accommodates your component pins and leads.

Trace widths ranging from mils can be used in these designs as they will be small enough to be routed directly into pads on most components. A basic example with an op-amp is shown below, where traces are being routed between a low-speed IC, some resistors, and capacitors. Designers need to determine the trace geometry requirements for their connections to ensure reliability and signal integrity.

Be sure to check your signaling standards to determine your routing requirements, which will include things like loss budget determines total length , impedance requirements, and allowed length mismatch in differential pairs or in a parallel bus. This involves setting minimum or maximum trace widths in your design rules, and your routing tools will use these specifications to set the trace width as you route traces. There are formulas you can use to determine the impedance in your design, or you can use more specialized applications to calculate the impedance you need in your design.

Single-ended and differential pair impedance will have defined geometry that is needed to ensure impedance goals are met. The fastest way to determine impedance is in PCB design software that includes a built-in calculator tool.

Not all PCB design applications will include this type of utility, and those that do produce results with differing levels of accuracy. The best PCB design applications will include an electromagnetic field solver that automatically calculates the required trace geometry. These tools will take the dielectric constant and copper roughness information in your PCB and use it to calculate the trace width and differential pair spacing needed to hit a target impedance. Trace routing topologies define how traces are routed between component inputs and outputs, as well as how traces are branched from each other to reach multiple components.

For example, DDR routing uses a fly-by topology, where a single bus branches off to reach multiple components in the design. In another example, SPI uses a similar bus topology, but with termination applied at the load points on the bus. Other components might use point-to-point topology to reach multiple components, which is most common when a design requires a single component communicating with multiple loads over a single IO interface.

Make sure you understand the routing topology needed in your signaling standards, as well as whether those traces require impedance control. Traces in your PCB layout are routed by simply pointing and clicking locations in the board. Along the way, copper traces will be fixed at the desired point where the user clicks the mouse, eventually spanning across the layout to the required location. Signal integrity is one area that is intimately related to PCB stackup design and routing. This simple guideline and the routing rules shown above will help prevent or reduce many signal integrity problems and will help ensure your board remains functional.

The most advanced routing tools that can help you stay in line with basic PCB routing guidelines are interactive. In other words, these tools are semi-automated, allowing you to define routes for a group of signals, and the routing tools will place traces such that they automatically obey your design rules.

In this type of routing, the design rules for your nets and groups of nets are checked automatically as you create your PCB layout. Many freeware and open source design programs force you to do everything manually, but advanced PCB design programs like Altium Designer can help you stay productive as you work to complete your PCB layout and route traces around your board.

The integrated design rules engine in Altium Designer automatically checks your routing as you place traces, allowing you to spot and eliminate errors before you finish the board.

Parent page: High Speed Design. With increasing device switching speeds, controlled impedance routing has become a hot topic for the digital designer. This article introduces how you can use the Signal Integrity analysis engine to match component impedances and the controlled impedance routing capabilities in the PCB editor.

There is a saying in engineering circles – there are only two kinds of electronics engineers working in digital design: those who have had signal integrity problems, and those who will. Not so many years ago the term signal integrity was one for the specialist and you only had to deal with it on high-speed designs. However, the device switching speeds in those high-speed designs are no longer anything special, in fact, they are rapidly becoming the norm.

As improving integrated circuit technology drives the size of the transistor down, the speeds at which they can switch goes up. And it is this switching speed that affects the integrity of digital signals. Thankfully many potential signal integrity issues can be avoided by following good design principles and implementing the design as a controlled impedance board. Achieving this does require specific design tool capabilities – you need analysis tools that can detect nets with potential ringing and reflection issues, and board design tools that allow you to achieve the correct routing impedances.

This article will help you understand what causes signal integrity issues and if your board is likely to suffer from them. Controlled Impedance Routing: configuring the routing widths and clearances, as well as the material properties and dimensions, to deliver the required routing impedance s. As device switching speeds increase, so too do the demands on the printed circuit board designer and the fabricator. As the length of the signal switching edge becomes shorter than the length of the PCB trace that carries it, the trace has to be treated as part of the circuit.

That trace has an impedance, which is referred to as the characteristic impedance Zo. The best way to manage the impact of these additional circuit elements is to design the trace routing so that the characteristic impedance is consistent over the length – a technique called controlled impedance routing.

The Simbeor impedance calculator calculates the width s required to achieve the specified impedance. In an ideal situation, all of the energy that comes out of a component output pin would be coupled into the connected track on the PCB, flow through the PCB routing to the load input pin at the other end, and be absorbed by that load.

If all the energy is not absorbed by the load then the leftover energy can be reflected back into the PCB routing, flowing to the source output pin. This reflected energy can interact with the original signal, adding to and subtracting from it depending on the polarity of the energy , resulting in ringing. If the ringing is large enough, it will affect the integrity of the signal, resulting in unpredictable, erroneous circuit behavior. So how do you know if this might occur?

If the source pin is able to complete its edge transition before the signal reaches the load pin, the conditions exist for your design to be impacted by reflected energy. If the source pin has a 1 nSec rise time, a route longer than. If your devices have this sort of rise time and you know you will have routing of this sort of length, then you might end up with signal integrity issues on the PCB. The speed at which the electrical energy can travel along the route is known as the propagation velocity, where:.

How do you avoid the situation where there is energy being reflected back and forth between the source and the load? You avoid it by matching the impedances. Impedance matching ensures that all the energy is coupled from the source into the routing, and then from the routing into the load.

Routing the board with regard to the impedance is referred to as controlled impedance routing or another way of saying it is that a board where impedances have been managed is called a controlled impedance PCB. There are two distinct elements to achieving impedance matching: the first is matching the components; the second is routing the board to give the required impedance.

You cannot achieve a controlled impedance PCB with routing alone. First, you must check, and if necessary, match the impedances of the components. Ideally, you want to detect nets that could have potential signal integrity issues during the design capture phase so that any additional termination components can be included before the board design process starts.

Since output pins are low impedance and input pins are high impedance, it is likely that you will need to add termination components to the design to achieve impedance matching. You can perform a signal integrity analysis on your design at the schematic capture stage. When you run the Tools » Signal Integrity command the Errors or Warnings dialog will often appear, indicating that not all components have signal integrity models assigned. The Signal Integrity analysis engine will automatically select default models based on the component designators, click Continue to use the defaults or Model Assignments to examine and change the models.

The Signal Integrity analysis engine will use defaults for the required impedance and average track length. It will also use default values for the signal stimulus the properties of the theoretical signal that is injected. These defaults can be configured once the Signal Integrity panel has opened, via the panel’s Menu button » Setup Options command. Note that the Signal Integrity analysis engine requires power planes for the reference planes, it is not able to use a signal layer covered by a polygon.

The Signal Integrity analysis engine installs as a System Extension. If it is not currently installed, click the Configure button to install it. When the Tools » Signal Integrity command is run the design is analyzed, any potential problem nets are identified in the Signal Integrity panel, as shown below. Testing the design for potential signal integrity issues during design capture.

From the panel, you can perform a reflection analysis on a selected net or nets. On the left is the analysis results for all nets in the design, select a net and click the button or double-click a net name to transfer that net to the Net field on the right of the panel, where you can perform a detailed analysis of that net, including:. The panel allows you to experiment with possible termination configurations and values.

Note that the Termination region of the Signal Integrity panel shown in the image above has the Serial Res option enabled. The section of the panel below that shows a series termination resistor.

This is where you define the minimum and maximum theoretical series termination resistance values that will be used for the reflection analysis disable the Suggest checkbox to enter your own values. The images below show two graphs of the results at the input pin of the net selected in the previous panel image. The first graph is the input pin in the net without termination; the second graph shows six sweeps, one for the original unterminated net, then five sweeps with the theoretical series termination resistance included at the source pin.

The five passes first pass at 20 ohms, last pass at 60 ohms are listed on the right-hand side of the graph. Clicking on each label highlights that result and displays the theoretical termination resistance value at the bottom right.

For this net, a series termination resistance of 40 ohms would produce the graph selected in the image on the right. The graph on the left shows the reflection analysis of a net with potential signal integrity issues; the graph on the right is the same net with a theoretical series termination resistor of approximately 40 ohms added. To hide a floating panel, press F4 when the panel is active the caption bar is colored.

Press F4 to restore the display of the panel. The second part of achieving a controlled impedance PCB is to route the board so that the tracks are a defined impedance. There are a number of factors that influence the impedance of your signal routing, including the dimensions of the routes and the properties of the materials used to fabricate the PCB. Simbeor’s model accuracy is validated through the use of advanced algorithms for 3D full wave analysis, benchmarking, and experimental validation.

The Simbeor engine supports all modern board structures and materials. The Simberian site also includes an extensive library of application notes and papers published by Simberian’s principal developer, Yuriy Shlepnev, as well as papers written in collaboration with other leading industry and academic researchers. Simbeor SFS is an advanced quasi-static 2D field solver based on Method of Moments, which has been validated by convergence, comparisons, and measurements.

The solver meshes dielectric and conductor boundaries and solves corresponding equations to build frequency-dependent RLGC matrices for the Telegraph equations. Simbeor SFS is not a full-wave solver as this is not needed to evaluate the impedance, delay, or attenuation in PCB interconnects, because of the quasi-TEM nature of the waves propagating there. Such waves can be accurately simulated with RLGC parameters extracted with a quasi-static 2D field solver.

A unique property of the Simbeor SFS solver is that it supports conductor roughness models. Note that it does not support a multi-layered conductor model plating , and the roughness is common for all conductors.

The solver is quasi-static because the solution does not include the high-frequency dispersion that takes place in microstrip lines higher concentration of fields in a dielectric with higher dielectric constant at high frequencies. Controlled Impedance routing is all about configuring the dimensions of the routes and the properties of the board materials to deliver a specific impedance. The Layer Stack Manager opens in a document editor, in the same way as a schematic sheet, the PCB, and other document types do.

The trace width required to deliver a specific impedance is calculated as part of the impedance profile, configured in the Impedance tab of the Layer Stack Manager. When these are correctly configured, the impedance calculator has sufficient information to calculate the:. To improve calculation speeds, impedance profiles are calculated in separate threads when available.

The calculated values are displayed in the Transmission Line section of the Properties panel , when the Impedance tab is selected in the Layer Stack Manager , as shown below. Main article: Defining the Layer Stack. The copper and dielectric fabrication layers are configured on the Stackup tab of the Layer Stack Manager. A fundamental requirement for controlling the impedance is to include a signal return path below each signal path. The Simbeor SI engine supports both plane layers, and signal layers covered by a polygon.

These return-path layers should be distributed through the board stackup. Ideally, they are arranged so that there is at least one return-path layer adjacent to each signal layer that is carrying controlled impedance routing.

The adjacent return-path layer provides the signal return path, and for reasons that will not be covered here, does so regardless of the DC voltage distributed by that plane. The return path current flowing through the plane will attempt to follow the same physical path as the route on the signal layer, so it is important to avoid introducing discontinuities, such as a split or cutout in the return-path layer underneath any critical signal routing.

As well as selecting a suitable order for signal and plane layers, you also need to define the material properties of each layer, including:. These values, and the routing width, all contribute to the final impedance. Achieving the required impedance then becomes a process of tuning all these values.

Keep in mind that possible copper and dielectric thickness values may also be limited, determined by the materials available from your PCB fabricator. To configure the layer stack for controlled impedance routing, switch to the Layer Stack Manager’s Impedance tab where you can add and configure an impedance profile.

From the target impedance and target tolerance, the software calculates the Trace Width. It is not uncommon that the calculated trace width will be a value that cannot be ordered, for example 0. The fabricator will advise what material thicknesses are available and what precision they can achieve for trace widths. Then it becomes a process of starting at the desired values, then testing the impact on the calculated impedance values when the dimensions are adjusted to what is available.

To support this process of testing and tuning the settings, the impedance calculators support forward and reverse impedance calculations. The default mode is forward enter the impedance, the software calculates the width. The icon indicates the calculated variable. To reverse the calculation and explore different trace widths for the selected layer, type in the new Width W1 value and press Enter on the keyboard.

 
 

ISO – Wikipedia.Interactively Routing with Controlled Impedances on a PCB in Altium Designer

 
 

ISO is an ISO standard for the computer -interpretable representation and exchange of product manufacturing information. The international standard ’s objective is to provide a mechanism that is capable of describing product data throughout the life cycle of a product , independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving.

STEP addresses product data from mechanical and electrical design, geometric dimensioning and tolerancing , analysis and manufacturing, as well as additional information specific to various industries such as automotive , aerospace , building construction , ship , oil and gas , process plants and others. The evolution of STEP can be divided into four release phases.

In the second phase the capabilities of STEP were widely extended, primarily for the design of products in the aerospace, automotive, electrical, electronic, and other industries. A major problem with the monolithic APs of the first and second releases is that they are too big, have too much overlap with each other, and are not sufficiently harmonized.

These deficits led to the development of the STEP modular architecture and series. The SMRL will be revised frequently and is available at a much lower cost than purchasing all the parts separately.

In December , ISO published the first edition of a new major Application Protocol, AP Managed model based 3d engineering , that combined and replaced the following previous APs in an upward compatible way:. AP was created by merging the following two Application protocols:. AP edition 2, published in April , extends edition 1 domain by the description of Electrical Wire Harnesses and introduces an extension of STEP modelisation and implementation methods based on SysML and system engineering with an optimized XML implementation method.

This new edition contains also enhancements on 3D Dimensioning and Tolerancing, and Composite Design. New functionalities are also introduced like:. In total STEP consists of several hundred parts and every year new parts are added or new revisions of older parts are released. Each part has its own scope and introduction. The APs are the top parts.

They cover a particular application and industry domain and hence are most relevant for users of STEP. Every AP defines one or several Conformance Classes, suitable for a particular kind of product or data exchange scenario. To provide a better understanding of the scope, information requirements and usage scenarios an informative application activity model AAM is added to every AP, using IDEF0. These interpreted models are constructed by choosing generic objects defined in lower level data models 4x, 5x, 1xx, 5xx and adding specializations needed for the particular application domain of the AP.

The common generic data models are the basis for interoperability between APs for different kinds of industries and life cycle stages. The requirements of a conformant STEP application are:. But because the development of an ATS was very expensive and inefficient this requirement was dropped and replaced by the requirements to have an informal validation report and recommended practices how to use it.

Today the recommended practices are a primary source for those going to implement STEP. Originally its purpose was only to document high level application objects and the basic relations between them. There is a bigger overlap between APs because they often need to refer to the same kind of products, product structures, geometry and more. And because APs are developed by different groups of people it was always an issue to ensure interoperability between APs on a higher level.

The Application Interpreted Constructs AIC solved this problem for common specializations of generic concepts, primarily in the geometric area. Modules are built on each other, resulting in an almost directed graph with the AP and conformance class modules at the very top. The modular APs are:. They both use ISO as their common reference data library or dictionary of standard instances. A further development of both standards resulted in Gellish English as general product modeling language that is application domain independent and that is proposed as a work item NWI for a new standard.

The original intent of STEP was to publish one integrated data-model for all life cycle aspects. But due to the complexity, different groups of developers and different speed in the development processes, the splitting into several APs was needed. But this splitting made it difficult to ensure that APs are interoperable in overlapping areas.

Main areas of harmonization are:. STEP programs. From Wikipedia, the free encyclopedia. ISO standard.
