This page details the improvements included in the initial release of Altium Designer 21, as well as those added in subsequent updates. Along with delivering a range of improvements that develop and mature the existing technologies, each update also incorporates a large number of fixes and enhancements across the software based on feedback raised by customers through the AltiumLive Community's BugCrunch system, helping you continue to create cutting-edge electronics technology.
Released: 29 September 2021 – Version 21.7.2 (build 23)
Welcome to Update 7 for Altium Designer 21. This update to Altium Designer continues to deliver improvements and enhancements to the software's core technologies, while also addressing many of the ideas raised by customers through the AltiumLive Community's BugCrunch system.
Implemented a 'Schematic was done in newer version' warning to notify users that new functionalities were introduced between the version of Altium Designer that was used to create the schematic, and the version used to open the schematic document. This feature functions in the same way as the PCB editor version warning.
The last active schematic sheet is now displayed after clicking on the text of the schematic document tab. This is very useful when there are a large number of schematic sheets opened that are included in the drop-down of the tab.
Cross-Reference settings have been moved from the Schematic - General page of the Preferences dialog to the Options tab of the Project Options dialog with additional options that allow you to select the supported object(s).
Use the Sheet Style and Location Style drop-downs to set the cross-referencing options. Enable the required supported objects.
Adding cross-references to the project allows you to easily follow the connective flow of nets between the schematic sheets in a project. Building on the support for automatically creating and updating cross-references recently introduced by the Schematic.UseAutomaticCrossReferences option, this new advanced option brings support for cross-references in a hierarchical project.
Enable the Automatic Cross References option in the Project Options dialog then use the right-click context menu to Jump to your choice of target location anywhere in the hierarchy.
This feature supports three modes described below that are enabled by setting the Value of the advanced option.
This mode also enables Port Actions >> Jump to Port.
The Show More feature simplifies the display of component parameters by reducing the list to only display those parameters that have been set as a favorite. However, you might prefer to always have all parameters displayed in the Component mode of the Properties panel.
To support this, when the new option is disabled, the Show More/Show Less feature is disabled, resulting in all of the component parameters always being displayed in the Component mode of the Properties panel.
The properties of rooms can now be configured and edited in the Properties panel. You can use the new mode to define the name, coordinates and outline vertices of rooms.
A Use Paste option has been added to the PasteMaskExpansion design rule, the Pad mode of the Properties panel, and the Pad Template Editor, alleviating the need to use a suitable negative value to remove Paste. Clear the checkbox to remove the paste from the targeted/selected pad(s).
Altium Designer now provides an enhanced flow that helps you to more easily use the benefits of the built-in Git-based version storage in Altium 365 for local projects. The enhancements are described below.
The ability to sweep more than two parameters during the Parametric Sweep has been added.
Added Waveforms and Functions drop-downs in the Add Output Expression dialog to allow you to select the required items.
The X,Y scale settings for plots are now kept during the simulation process for opened and saved .sdf documents.
The following variables are now supported in DC and Transient Analysis:
The following features have been taken out of Open Beta and transitioned to Public in this release:
Released: 20 August 2021 - Version 21.6.4 (build 81)
Released: 22 July 2021 – Version 21.6.1 (build 37)
Welcome to Update 6 for Altium Designer 21. This update to Altium Designer continues to deliver improvements and enhancements to the software's core technologies, while also addressing many of the ideas raised by customers through the AltiumLive Community's BugCrunch system.
Added the Show Automatic Sheet Numbering option, which enables you to control the visibility of sheet numbers. The option has been added to the System - Projects Panel page of the Preferences dialog and the Projects panel settings.
Cross References, which tag Ports and Off Sheet Connectors with sheet and location coordinates of connected Ports/Off Sheet Connectors, is a popular feature to help trace net connectivity in a non-hierarchical design. Since it is a project-level setting, the option to enable Automatic Cross References is located in the Options tab of the Project Options dialog as shown below.
With this change, the Port Cross Reference Add and Remove commands were removed from the Reports menu and are replaced with the new Automatic Cross References Settings command. Selecting this command will open the Options tab of the Project Options dialog where you can toggle the feature on/off.
Cross Reference values are now displayed in the Properties panel for Ports and Off Sheet Connectors, simplifying the task of identifying the Cross Reference(s) being applied to the selected Port or Off Sheet Connector.
The Parameter Table Editor dialog has been improved by displaying the columns in alphabetical order, which helps during searching when there is a large number of parameters.
In previous versions, the track segment being dragged could not be dragged beyond an existing stationary segment once the dragged segment became aligned to the stationary segment. This behavior can now be overridden by setting the new PCB.Drag.EnhancedExpansionBehavior in the Advanced Settings dialog to a value of 1. Set the option to 0 (zero) to retain the previous behavior.
To better support the situation when you want to continue dragging the segment beyond the adjacent segments and not have segments merge, the Merge Parallel option has been added to the Interactive Sliding panel.
Disable the option in the panel (or press the R shortcut) during dragging to inhibit merging.
Added the Pad Entry Stability option to the PCB Editor - Interactive Routing page of the Preferences dialog. This option allows you to protect centered pad entries from being modified during glossing. Specify the level of protection required. The higher the number, the greater the protection; '0' gives no protection. Learn more about Pad Entry Stability.
Embedded board arrays are used to design and generate output for a PCB fabrication and assembly panel including pick and place data. The Pick and Place Setup dialog now includes all of the component parameters allowing you to configure the pick and place output as required.
A button that allows you to quickly place a comment in a project saved in a Workspace has been added. To place a comment, click at the top right corner of the design space. The cursor changes to a crosshair with a blue circle at the center. Position the crosshair where you want the comment located on a PCB, PCB library, schematic, or schematic library document then click. The Comments panel opens in which you can enter then post your comment.
The Open Project dialog has been improved with this release. The selected project's information is now displayed at the right by default rather than needing to click to open the information pane. Additionally, an Open Project As Copy command has been added that allows you to copy (clone) the project. Click the command to open the Create Project Copy dialog then enter the desired name and description of the copy.
The Make Available Online Success dialog opens after successfully making the project available in the server through the Make Available Online dialog. The dialog includes a link to the project in your web browser.
The right-click project menu has been updated and reorganized in order to consolidate the menu. History and Version Control have been combined into one option (History & Version Control). Storage Manager and Local History have been relocated to the submenu of the new History & Version Control option. In addition, Local History has been renamed Local History (Legacy).
The Show File History command has been added to provide a dedicated Project History view in which a progressive timeline of major events relating to the file, such as its creation and commits, can be viewed. This command can be accessed by right-clicking on a managed file in the Projects panel, then choosing the History & Version Control » Show File History command from the context menu.
The component caching performance has been improved, which reduces the lag when placing a component from the Components panel.
The Print Preview, Printout Properties, and Printer Configuration for dialogs have been consolidated into one dialog that includes options to configure your printouts. The new dialog allows you to configure your printouts in one place rather than needing to access separate dialogs. The new dialog is accessed by clicking File » Print from a schematic, PCB, PCB Library, or Draftsman document.
Added a Justification property to the following Draftsman objects:
Select the desired justification by clicking on an arrow that corresponds with the desired justification or the circle to center. Examples are shown below.
In the Variants Display drop-down of the Document Options mode of the Properties panel, Cross has been added as an option to make the visibility of the variant more prominent. Additionally, options have been added to include Not Fitted Text and for configuring the text.
The hexagon and flag have been added as ASME callout shapes. These new shapes help prevent conflicts with existing mechanical drawing standards.
Math functions can now be used in output expressions.
The set of the Integral type functions can now be used in output expressions.
Output Expressions in Multivariate analysis are now supported.
Node voltages now include the v -prefix in output expressions and in the Sim Data panel.
Released: 22 June 2021 – Version 21.5.1 (build 32)
Welcome to Update 5 for Altium Designer 21. This update to Altium Designer continues to deliver improvements and enhancements to the software's core technologies, while also addressing many of the ideas raised by customers through the AltiumLive Community's BugCrunch system.
Added the ability to use the spacebar to toggle the Action off and on in the Engineering Change Order dialog.
Added the 'Show <component> in <server>' command to the right-click menu of the Component Actions sub-menu, which when used, opens the Explorer panel with the specified component selected. This command is only available for a PCB document that is part of a managed project.
Added a dialog that alerts you to the presence of shelved polygons before generating certain outputs. The outputs included are Gerber, Gerber X2, ODB++, PCB Print, and IPC2581. Click Generate Output to continue or Cancel to abort the output generation. If the generation was aborted, repour the polygon(s) then regenerate the output.
When placing primitives on a PCB or PCBLIB document, rotation is now 0 by default; change the rotation during placement as needed.
A BOM Compare report has been added for managed projects that include a BOM document (*.BomDoc). It is a common occurrence for components to change between design releases. The BOM Compare report displays what has changed between the current design, and the selected released revision.
The BOM Compare report can be configured then generated in the following ways:
Learn about the options and controls in the BOM Compare version of the Report Manager dialog (shown below) by clicking here.
The image below is an example of a BOM Compare report generated as a PDF outjob.
Added a decision dialog that allows you to choose how to remove a document. You can choose to permanently delete the document or to only exclude the document from the project but not delete it entirely. The dialog opens when you choose the Remove from Project command from the right-click menu of a selected document.
Added new math functions to the existing list in the Add Wave to Plot dialog. The dialog is accessed by choosing Wave » Add Wave from the main menus when an *.sdf file is the active document.
Default values for simulation model parameters are now used in the Sim Model dialog. Default parameter values are displayed as grayed-out text; custom values are displayed in white text. If a custom value is removed, the default value will be restored. Empty values are not allowed.
Released: 25 May 2021 – Version 21.4.1 (build 30)
Welcome to Update 4 for Altium Designer 21. This update to Altium Designer continues to deliver improvements and enhancements to the software's core technologies, while also addressing many of the ideas raised by customers through the AltiumLive Community's BugCrunch system.
The PCB editor can help manage the routing as you move a routed component. The Component re-route option on the PCB Editor - Interactive Routing page of the Preferences dialog instructs the routing engine to attempt to re-route the connections impacted by the move as soon as the component is dropped, and the Move component with relevant routing option instructs the routing engine to move relevant routing together with the moving component(s). Relevant routing includes via fanouts, escape routes and interconnects between the component's pins. Use Shift+Tab to toggle this option on/off while moving a component.
If the component has a large number of pins with relevant routing attached, this can become a processor-intensive task. To help you manage this, the up to option has been added. Use the option to define the maximum number of pins the moving component can have before the routing engine no longer moves the relevant routing with the component.
Added the ability to observe SMD rules (SMD Entry and SMD to Corner) in 'Any Angle' gloss. In the presence of these design rules, routing now exits pads orthogonally and does not turn for a certain distance, which allows the trace to leave the solder mask opening before approaching the adjacent pad. This avoids an exposed metal proximity issue and the risk of solder bridging.
Added the 'Use Animation' option on the PCB Editor - Display page of the Preferences dialog that allows you to toggle animation on/off while zooming, flipping the board and switching layers.
Restored the ability to change the coverlay color in the View Configuration panel.
Added new controls in the Properties panel for an Embedded Board Array object to help you better define the board array. The Additional Options region on the General tab allows you to enable/disable a Drill Table, Layer Stack Table, or Dimensions. The new Parameters and Layers tabs allow you to select the parameters and/or layers to be transmitted. The settings configured on the Layers tab will be reflected in outputs, e.g., PCB printouts.
To improve the responsiveness in the PCB editor, the following post-processing behavior has been introduced:
Altium Designer now offers the ability to migrate projects that use an external VCS system to a fully-managed Altium server project that hosts the design files in the server's own Git repository. The fully-managed project can then benefit from the server's native VCS features, such as the event-based History timeline. The Make Available Online dialog now offers a Migrate to <server> Versioned Storage option that enables the VCS migration process in place of simply mirroring the project structure in the server.
If the external VCS project is already managed in the Altium server as a mirrored project (synchronized local-server files), its VCS files can be migrated to the server's native Git repository using the Migrate to Versioned Storage command available from the Project History view, the Project Options dialog, and the Projects panel's Version Control right-click context menu.
Added the ability to change the revision state of a component in the Components panel. The command is accessed by right-clicking on one or more components then selecting Operations » Change State from the context menu. The Batch state change dialog opens in which you can change the revision state of the component(s).
After making updates, if you have not saved the document (PCB, SCH, Component, etc.,), the dialog shown below will open. By enabling the Save to Server option then clicking Save, the changes will be saved to the server as well as locally.
If you have made changes to the document and have saved the changes locally, the dialog shown below will open to alert you to also save the changes to the server (if required). Click Do nothing if you do not want the changes saved to the server.
Confirm Save Dialog Enhancements
The Confirm Save for Modified Documents dialog has been enhanced to allow you to choose if you want unsaved modified documents saved to the server or not when closing Altium Designer. Use the drop-down to choose specific documents to save or click Save All to Server to save all listed documents to the server.
If a local document was also modified, the Confirm Save for Modified Documents dialog will list those documents as well as shown below.
Added the Show No BOM option, which, when enabled, displays the part in the Board Isometric View even if it is not in the BOM.
Added the Override Color option for a Board Fabrication View that allows you to set the default color for all layers.
Comment and Design Item ID parameters have been added to the drop-down list in the Component Display Properties dialog (accessed by clicking the Components button in the Board Assembly View mode of the Properties panel).
Added the ability to import Allegro footprint files (*.dra) using the Import Wizard in order to streamline the import process.
The Ansys EDB Export Options dialog has been added, which allows you to configure the ANSYS export. The dialog is accessed by clicking File » Export » Ansys EDB from a PCB document then choosing the desired folder in the Windows dialog that opens.
Added a set of default simulation models in the Sim Model dialog that allows you to quickly choose defaults from a list. Select the required model from the Model Type drop-down.
Released: 29 April 2021 – Version 21.3.2 (build 30) - Hot Fix
Released: 22 April 2021 – Version 21.3.1 (build 25)
Welcome to Update 3 for Altium Designer 21. This update to Altium Designer continues to deliver improvements and enhancements to the software's core technologies, while also addressing many of the ideas raised by customers through the AltiumLive Community's BugCrunch system.
Miters are short diagonal segments that are automatically added during routing to prevent the placement of 90-degree corners. The size of the miter is defined by the current Miter Ratio. The default behavior is when a track segment is dragged any attached miters are also dragged.
With this release, you can choose to include or exclude the miter(s) during dragging using the Include Miters option on the Interactive Sliding mode of the Properties panel. Press the C shortcut during dragging to drag without miters. Press C again to re-enable dragging with miters.
To simplify controlling the folding process of a rigid-flex PCB, the 3D Locked checkbox has been added to the Board Region mode of the Properties panel. Only one Board Region can be locked; it will be the stationary region when the board is folded in 3D View mode.
Added the PCB.Rendering.MultiselectionDrag option in the Advanced Settings dialog that allows you to control the number of primitives displayed when dragging multiple selected objects.
The ability to export comments to a separate document has been added. This allows you to have a full history of design reviews, so you no longer need to keep a separate document or have to perform duplicate work.
This feature is accessed in the following ways:
After you have added the new Export Comments report output, right-click then choose Page Setup to open the Export Comments Properties dialog opens in which you can configure the export.
The new Comment Export Configuration dialog has been introduced that allows you to set the period of time for the comment export and include screenshots if desired when exporting a comment. The dialog is accessed by right-clicking on Export Comments under Report Outputs in an outjob then select Configure from the context menu. Click Export to export the comment and open it in the associated file type application.
Search times in the Manufacturer Part Search panel have been improved to deliver faster results when a category is selected or a search is performed within a category.
It is not uncommon for components to be placed on different grids. It could be a radial grid defined for a circular board, a custom component grid for a specific region of the board, or a mechanical grid defined by the mechanical engineer and pushed to the PCB editor using CoDesigner, Altium's ECAD-MCAD collaboration solution.
Custom grid location details, such as a user-defined or MCAD-defined component grid, are included in the Location region of the Properties panel when a component is selected. A custom grid can use different units from the Global Board Snap Grid, but will always display in the units currently chosen in the PCB editor.
Custom grids are defined and edited in the Board mode of the Properties panel (displayed when nothing is selected).
Added a Display holes option in the Board Isometric View mode of the Properties panel that allows you to choose if holes are displayed. Use the drop-down to select the desired display option: None, All, or Pads only.
Added the ability to configure the Interval and Period for Transient Analysis in the Simulation Dashboard panel. Use the new fields to set the interval and the number of periods and points per period.
Default values for AC analysis are now used in the Advanced Analysis Settings dialog (accessed by clicking Settings in the Simulation Dashboard panel).
The 'temper' variable and the 'idtmod' function are now supported in math expressions for LTSPICE models.
Settings for Group Tolerances in Monte Carlo analysis have been added to the Advanced Analysis Settings dialog to more precisely define the simulation.
Added the 'RNODETOGND' advanced parameter with a default value of '1e12' to the Advanced Analysis Settings dialog. This parameter is used to process the DC path to ground.
Released: 19 March 2021– Version 21.2.2 (build 38) - Hot Fix 2
Released: 11 March 2021– Version 21.2.1 (build 34) - Hot Fix
Released: 04 March 2021 – Version 21.2.0 (build 30)
Welcome to Update 2 for Altium Designer 21. This update to Altium Designer continues to deliver improvements and enhancements to the software's core technologies, while also addressing many of the ideas raised by customers through the AltiumLive Community's BugCrunch system.
The handling of differential pairs with arcs in corners has been improved, the corner arcs are now concentric (share the same center point), ensuring the within-pair clearance remains the same around the corner.
Round pad entry algorithms have been enhanced to tend to align the incoming route orthogonally or diagonally during dragging, reducing the tendency for the routing to add a small jog or bump within a pad during dragging.
The Ctrl+Arrow shortcut is a popular technique for nudging a selected component one grid-step (hold Shift to nudge 10 grid steps). This technique now supports the Component re-route option (Interactive Routing page of the Preferences dialog) - the routing being updated as the component is nudged.
In Board mode of the Layer Stack Manager, the layers are drawn to approximately represent the fabricated thickness of each layer (use the Ctrl+MouseRoll shortcuts to zoom this view). To help when working with thicker, high-layer-count boards, the Realistic Ratio option has been added. When this option is disabled, each layer continues to display at a thickness that is proportional to their contribution to the overall thickness but at a reduced rate.
Added the ability to lock the width and height of a rectangle object. Toggle the link icon in the Rectangle mode of the Properties panel to lock/unlock the aspect ratio when changing the width/height of the rectangle. The icon will change to indicate the current lock/unlock state.
Added the Explode Rectangles to Free Primitives command to the Tools » Convert sub-menu that allows you to convert a Rectangle object back to its original set of primitive objects.
When a document that belongs to a project on a server has been modified and saved locally, the Projects panel entry displays a Save to Server link, which alerts you to also save the modifications to the server. Clicking the link opens the Save to Server dialog in which you can select the documents to be saved. After clicking OK, the documents are saved to the server and the Save to Server link disappears from the Projects panel.
The Remove from Project command, which was previously removed, has been restored and renamed Exclude from Project to make the function of the command more apparent. The command is located on the right-click menu of the Projects panel (for projects under version control).
The Projects panel right-click Delete command is now available for all types of projects, i.e. not only for version-controlled projects.
In order to prevent the creation of duplicate parts in the Single Component Editor, the Duplicate component by Name and Duplicate component by PCL violation types have been added to the Data Management - Component Rule Checks page of the Preferences dialog. The Report Mode of both violations is No Report by default.
The Hyperlynx (*.HYP) exporter has been enhanced to include component values (components' Value parameter) and part numbers (components' Comment property). Previously, the exported files only included layer and designator information. This information simplifies the process of assigning component models in Hyperlynx.
Added generation of special symbols for SPICE components described by the .MODEL command. Note in the image below, the model file
models3.mdl is the active library. When a supported model-kind is selected in the list, a suitable component symbol is automatically selected from the
Simulation Generic Components library. This allows you to place the chosen model as a symbol, directly onto the schematic.
The table below lists the supported model-kinds and the library component from which the symbol is placed.
(SIM Library Design Item ID)
|Resistor||.MODEL <model name> RES||Resistor|
|Capacitor||.MODEL <model name> CAP||Capacitor|
|Inductor||.MODEL <model name> IND||Inductor|
|Diode||.MODEL <model name> D||Diode|
|Bipolar transistor||.MODEL <model name> NPN||BJT NPN 4 MGP|
|Bipolar transistor||.MODEL <model name> PNP||BJT PNP 4 MGP|
|Junction FET||.MODEL <model name> NJF||JFET N-ch Level2|
|Junction FET||.MODEL <model name> PJF||JFET P-ch Level2|
|MOSFET||.MODEL <model name> NMOS||MOSFET N-ch Level1|
|MOSFET||.MODEL <model name> PMOS||MOSFET P-ch Level1|
Added support for *.cir files as SPICE library files.
Default values for AC, DC and Transient Analysis input data fields are now supported.
Released: 12 February 2021 – Version 21.1.1 (build 26)
Welcome to Update 1 for Altium Designer 21. This update to Altium Designer continues to deliver improvements and enhancements to the software's core technologies, while also addressing many of the ideas raised by customers through the AltiumLive Community's BugCrunch system.
Generic Components are basic components that can quickly be placed in a design without the need to find and choose a specific manufacturer part from the available component sources. Use them as placeholders that can easily be replaced by a suitable component later in the design process. They also can be considered virtual or parametric components.
The Design Item ID field in the Generic Component mode of the Properties panel has been changed to a Replace button. The Replace button functions the same as the in the previous Design Item ID field and was changed to more clearly define the function. Clicking Replace opens the Replace Generic Component dialog in which you can select the desired component. After selecting then clicking OK in the Replace Generic Component dialog, the generic component on the schematic will be replaced with the selected component.
A read-only Comment field has also been added to the Generic Component mode of the Properties panel. The field defaults to displaying the ComponentType value, with other parameter values being appended as they are defined.
Generic components can be used as placeholder components and the properties can be defined as the design progresses. To help with this process, a list of all of footprints available in the connected Workspace can now be accessed.
The list of available footprints includes:
Other Generic Components interface updates (in Closed Beta Only) include:
► Learn more about Generic Components.
When selecting a local schematic sheet template (Design » Sheet Templates » Local), the Choose another file option has been renamed Load From File in order to clarify the function of the command.
A visibility icon ( ) has been added to the CrossRef parameter for the Port and Offsheet Connector objects. Enable/disable the icon in the Properties panel for each object as your needs dictate. The image below shows the visibility icon enabled for the CrossRef parameter of a port that is selected on the schematic sheet.
Rigid-Flex 2.0 brings support for all current types of rigid-flex PCB design. The first step was the object-level improvements to board regions and bending lines that were recently released. This update sees the addition of the Board view mode in the Layer Stack Manager, which greatly simplifies the definition and organization of the various substacks needed in a rigid-flex design.
Key improvements in Rigid-Flex 2.0 include:
The Layer Stack Manager's new Board view gives an excellent Z-plane representation of the overall board structure. Because many rigid-flex designs use the same substack configuration in different regions of the board, commands have been included to quickly replicate an existing substack in a new location. Select a substack, then right-click to insert a copy of that substack before or after any of the existing substacks, or copy and paste the substack to a new location (displays the Insert Selected Layers dialog).
As well as selecting a substack, you can also select specific layers within a substack and copy/paste these to a new location. Hold Shift as you click on a layer to select an individual layer. Continue to Shift+Click on other layers to build up the set of selected layers. Alternatively, Shift+Click on the first layer you require, then move straight to the last layer and Shift+Click to select it; all layers in between will also be selected.
You can then drag and drop the selected set of layers horizontally in the Board view to create a new substack of those layers or right-click and use the commands in the context menu (as demonstrated in the video below).
To complete the set of pre-defined 3D views available, Flipped Isometric View has been added to the selection of views in 3D view mode. Use the View » 3D View Control » Flipped Isometric View menu command or the Ctrl+Num0 shortcut keys.
The Collaboration Bar and user notifications have been updated to provide additional status information between designers working on the same project where 'soft locks' are applied to documents being edited. The lock is associated with the designer that first modifies a document, and this can be overridden by other designers. The current collaboration status is indicated in both the Projects panel and on the Collaboration Bar, which now shows collaborating users in separate viewing and editing groups.
The user interface updates also include information and action dialogs that pop up when key collaboration events occur, such as when you are attempting to make local changes to a document that is being edited (is in a modified state) by another user. This condition is likely to create a version conflict, so the dialog offers the choice of reverting your local changes or ignoring (overriding) the remote soft lock. This dialog replaces the previous Edit Document dialog.
► See Collaborators Visualization and Conflict Prevention for more information.
A common ready-for-release test used by many designers is to compare the Gerber files generated from the current release with the Gerber files from the previous release. This can be achieved in the Project Releaser once the project has been prepared for release. The Comparison is performed in Altium 365. Your default web browser will open your Company Workspace and display the results.
► Learn more about the Gerber Comparison feature.
When a template has been set as the default on the Data Management - Templates page of the Preferences dialog, it now displays as My Default versus Default, in order to distinguish it from system defaults.
Local and server templates can now be accessed and selected for multi-board schematic documents.
The browsing of Local and Generic simulation libraries has been merged to simplify working with simulation sources and generic components. This change is reflected in the user interface with the removal of the Generic button from the Source selection options in the Sim Model dialog. Both local library types now can be accessed when the Local option is selected.
More circuit objects are now available as sweep variables for the DC Analysis. Objects such as resistors are included for selection in the drop-down variable list, but not capacitors and inductors.
The Simulation engine now supports the
ddt and LTspice
delay functions for Transient Analysis.
The collected Simulation result entries in the Simulation Dashboard panel can now be renamed and a description added.
A Plot Number field has been added to the Add Output Expression dialog, which allows you to choose the plot in which the simulation data will be displayed.
Released: 11 January 2021 – Version 21.0.9 (build 235) - Hot Fix
Released: 17 December 2020 – Version: 21.0.8 (build 223)
Enhanced Document Commenting
In conjunction with the recent updates made to Commenting features in an Altium 365 Workspace, Altium Designer now offers a parallel set of revised and enhanced Commenting capabilities when connected to an Altium server.
Commenting in the design space has been notably improved in terms of graphics, usability and relevant information, and remains backward compatible with previously placed comments. Comments are now placed directly from within the Comments panel, include a preview screen capture, offer freehand drawing capabilities, the mention/assignment of team members, and flexible visibility and filtering options.
Schematic Editor Productivity Improvements
New and improved tools simplify the task of analyzing the connectivity in a schematic project. Hover the mouse over a net to examine both the logical (schematic) and the physical (PCB) net name; Alt+Click on the net to highlight that net throughout the project; and Alt+Double+Click on the net to display a tree of all sheets that the net is on, then click to check out that net on one of those sheets.
Design Collaborator Visualization and Conflict Prevention
To fulfill the need for real-time document sharing status and control in an Altium design editing environment, a series of updates to both the Altium design and server platforms has introduced a new system for visualizing and reacting to the current status of shared design documents.
The system allows you to see, in real-time, who is viewing or editing a shared document, and is enabled by the free flow of document sharing data between design clients via an Altium Workspace (required). The visualization for collaborators is realized through a series of new status icons, a Collaborators Bar and additional file locking logic.
Generic Components - Closed Beta Only
This release introduces the concept of standard Generic Components, which can quickly be placed in a design without the need to find and choose a specific manufactured part.
Generic Components are intended as placeholders that are easily replaced by parameter-matched real-world components later in the design process.
SPICE Simulation User Interface Updates
Following on from the recent introduction of an advanced new SPICE Simulation engine for Altium Designer, which delivered improved speed, solution convergence, accuracy and reliability, this new release focuses on user interface improvements to the software's mixed-signal SPICE Simulation workflow.
The Simulation interface updates include a new intuitive Simulation Dashboard panel, a revised Sim Model dialog and general interface updates. The new Simulation workflow (based on the Simulation Dashboard) is offered as an alternative to the existing approach based on the Analyses Setup dialog. Also included is a comprehensive range of ready-to-use Simulation Generic components.
New Design Rules Editor
The new design Rules Editor offers an alternative approach to viewing, creating and managing the design constraint rules used for PCB layouts. Provided as a document-based user interface, the reimagined Rules Editor coexists with the existing Rules and Constraints Editor, but takes a design-orientated rather than rule-orientated approach to PCB design rules and constraints.
Accessed from within the existing Rules and Constraints Editor, the new Rules Editor takes a simplified, more intuitive approach to the creation of design rules by avoiding query-based rule scoping, integrating multiple rules by object type, automatically deducing and applying rule priority, and more...
New PCB Length Tuning Patterns
This release sees extensive improvements to the PCB editor's length tuning technologies with the introduction of new Trombone and Sawtooth tuning patterns. These new tuning patterns are rendered within a tuning sleeve, making it easy to slide the pattern along a route and around corners.
