What’s new in Altium Designer 25.4.2 Build 15?
(Released on 13-03-2025)
Schematic:
- Minor update to the graphics for a device sheet symbol that employs the ‘Repeat’ keyword (in a multi-channel design). The set of stacked device sheet symbols are now drawn with rounded corners.
- Concatenation of special strings with numeric (integer) values would result in unexpected arithmetic operations and ultimately an incorrect overall string being presented. A note has been added to the documentation to clarify that such a parameter value must be placed in single quotes, thereby preventing it from being interpreted as a number and excluding it from any arithmetic operation.
- After using the Alt+click shortcut over a net object (to select that object and to highlight all objects associated to that net across all sheets of the active design project), all other objects on the schematic would remain in a greyed-out state, with no way to clear the highlighting, save for restarting Altium Designer.
- In some cases when working with the Properties panel for a schematic document, the error “System.NullReferenceException: Object reference not set to an instance of an object” would be encountered.
- Added visibility of dynamic parameters in the Properties panel for a placed (and selected) component on a schematic, using a combination of two advanced settings options – ‘Schematic.UI.ShowMoreOrLessParameters’ and ‘Schematic.ForceLoadDynamicParametersInIPP’.
- For a component parameter whose value includes one or more concatenated special strings, display of the value in a chosen variant would change from real value to “#NAME?” when the component variation was toggled from ‘Fitted’ to ‘Not Fitted’ in the Variant Management dialog.
- The ‘Report Project Hierarchy’ command (on the Schematic editor’s main Reports menu) was not functional and did not generate a .rep file, as expected.
PCB:
- After creating a single layer PCB and placing a layer stack table in the design space, the signal layer would disappear from the table after closing and reopening the PCB document.
- For a Rigid-Flex PCB with multiple Flex sub stacks, one on top of another (e.g. Flex Top stack above Flex Bottom stack), the routing width for the Flex Top stack region was not following the applicable design rule value. Instead, the Rigid stack routing width rule value was being used.
- For a specific design, Altium Designer would freeze when attempting to move/drag a particular track.
- With the option ‘Remove Net Antennas’ enabled (PCB Editor – Interactive Routing preferences), net antennas were not being removed as part of the automatic trace loop removal feature.
- Backdrills were being ignored when interactively routing, leading to clearance violations with backdrill vias.
- For a specific and large RF design, interactive routing performance was found to be considerably slow.
- When exporting a design to DXF format, the paste mask was missing for any pad set to use a predefined or custom shape.
- For a specific design with complex outline and large number of cutouts, routing performance was very slow.
- In some PCB designs and using the Interactive Router in its ‘Follow Mode’, track being routed would not actually follow the contour of the board.
- It was not possible to access the Edit Room Definition dialog for a placed room, either by double-clicking on the room or by using the Properties command on the associated right-click context menu.
- In a specific case and when starting to interactively route a diff pair, an Access Violation (at address 00007FFA06D76588 in module ‘RouterEntry.dll’) would be encountered.
PCB CoDesign:
- After a merge failure an error was being encountered, rather than changes being rolled-back and the document being returned to its pre-merge state.
- After reverting a merge the document is left in the ‘Merged’ state, rather than changes being rolled-back and the document being returned to the ‘Locally modified’ state.
Constraint Manager:
- For a specific design project, accessing the Constraint Manager from the PCB would take a long time and switching to the Physical view would take far longer still.
- The schematic constraints document (Constraints.xml) is now added to the project (on first save of the Constraint Manager) and made available through the Projects panel (in the Settings/Constraints sub-folder). In addition, constraints data in the document is reloaded/refreshed after updating the project from the connected Workspace.
- For a PCB design that showed no differences when performing an update to the PCB or running the Differences report output from an OutJob, the Differences report would incorrectly fail during the validation stage of the release process (when using the Project Releaser), flagging changes existing in constraints.
- Values for clearance between diff pairs and the gap between sides within a diff pair were incorrect in the Applicable Binary Rules dialog, compared with the values in the Constraint Manager.
- For a parameter set directive including a defined net class, after syncing/importing with/to the Constraint Manager, it is now possible to rename the net class from the Properties panel, when the directive is selected on the schematic.
- The ‘Graphical Custom Topology view’ feature, delivered by the ConstraintManager.TopologyGraphAvailable option and the ‘Migrate Project to Constraint Manager Flow’ feature, delivered by the ConstraintManager.ProjectMigrationWizard option (Advanced Settings), are now officially made Public with this release (both ON by default).
- Added support for the auto-creation of custom topologies for xNets that traverse discrete elements with more than 2 pins (e.g., a bank of resistors in a single part).
Draftsman:
- When specifying the Units and Dual Units for a Draftsman-based document (as part of Document Options in the Properties panel), the entries in the corresponding drop-down menus are now presented in short form (e.g., ‘cm’ instead of ‘Centimeters’).
Wire Bonding:
- Where a diff pair was being routed to a die that uses bond wires, the bond wires were violating the applicable diff pair routing rule (for width).
- For a wire bonding component placed within a cavity on an internal layer, die pads and bond wires were not rendering correctly (‘floating in air’) when viewing the PCB in 3D.
3D-MID Design:
- In some cases when placing track on the substrate in “Walkaround Obstacles” interactive routing mode, the router would ignore obstacles, leading to the creation of unexpected short circuits and clearance violations.
Harness Design:
- When configuring cavities, values for ‘Strip Length’ and ‘Pull Off Length’ can now be defined for rows where no cavity type has been specified.
- Parameters defined for cavity parts and associated parts were not being propagated to the ActiveBOM document.
- After changing the units for a HarDwf document at the document level (Document Options), the chosen units were reflected in the Length Units field for a selected wiring list, but the values were not being updated in the Length column.
- In a specific case, removing a particular harness covering from a harness design’s layout drawing document resulted in the error “Index was out of range. Must be non-negative and less than the size of the collection…” being encountered.
Platform:
- In some cases when working within an OutputJob document, an Access Violation (at address 000000014101CB39 in module “WorkspaceManager.DLL”) would be encountered.
- In some cases when first starting Altium Designer, the vertical scrollbar for the Projects panel was not being drawn correctly and could not be accessed/used until after collapsing/expanding some entry in the panel itself.
- The ‘Harness & Multi-board View Only Mode’ feature, delivered by the System.ViewOnlyMode.Support option (Advanced Settings), is now officially made Public with this release (ON by default).
- After placing a TActionList component and drawing the required button on a script Form, attempting to access the ActionList Editor would result in an Access Violation (in module ‘EditScript.DLL’) being encountered.
Data Management:
- After editing and releasing multiple components (from the Component editor in its Batch Component Editing mode), the data was not being refreshed automatically in the Explorer panel.
- In some cases for multi-channel designs using managed sheets, the Project Releaser would ignore applied Board Level Annotation, resulting in generation of a BOM with incorrect designators.
- When creating a comment for an alternative item in an ActiveBOM, the comment window would open partially off-screen and also appear with the header ‘Row was removed’.
- After choosing a replacement alternate component for a component entry in a defined variant, the parameters were not being directly updated to those of that newly-chosen replacement.
- In the Explorer panel, the ‘Part requests’ folder is now hidden if access to managed process workflows functionality is available.
- With multiple users working on a project in an Altium On-Prem Enterprise Server under SVN control, after one user migrates the project to the Server’s built-in Git repository, another user, using the ‘Update from Server’ control (and subsequent ‘Update local project folder’ option), would encounter the error “Failed to update local project”.
- When defining a Harness Wiring model (for a Harness Wiring component), attempting to ‘Add Supplier Link And Parameters to Component’ from an SPN tile of a chosen part in the Manufacturer Part Search panel, would cause Altium Designer to freeze.
- When creating a new item through the Explorer panel, the Create New Item dialog’s Revision ID field would present the ID using the revision naming scheme manually chosen for the last created item of that type, instead of the correct ID based on the item’s actual default naming scheme.
- When saving a new component to a connected Workspace (with the Component editor in its Single Component Editing mode), the release would fail if a release note was entered of more than 255 characters.
- For a defined project template in a connected Workspace whose Item Naming for project release uses custom project and variant parameters, release of a new project created from that template would result in generated data sets (Source, Fabrication, Assembly, Custom) not obeying that defined naming. Several custom parameters were being replaced with built-in parameters or removed entirely.
- The ‘Save to Server’ command was not available on the context menu associated with the VCS status icon, for the project document entry in the Projects panel.
- In some cases, SiliconExpert data in an Excel BOM exported from a Project’s ActiveBOM, was not the same as the original data in the ActiveBOM itself.
- In some cases and for a very large project with a considerable number of documents, it would take a very long time to update the VCS status of the project.
- Placing a managed schematic sheet onto a schematic in a Workspace project and saving the project to the Workspace would result in incorrect operation of VCS statuses in the Projects panel, with the status for some documents stuck at ‘refreshing’.
Import/Export:
- When importing a specific xDX Designer design, a multi-part component was incorrectly being imported as separate parts.
- Added the ability to quickly toggle the inclusion state of multiple selected layers on the ‘Current User Layer Mappings’ page, when importing a Mentor Xpedition design.
- When importing an xDX Designer design, bus entries were being imported incorrectly on the generated schematic document(s).
- When attempting to export a rigid-flex design to STEP 3D or PARASOLID format and the design included routing tool path primitives, export would fail if, in the Export Options dialog, the ‘Export Folded Board – Rate’ slider was set to anything other than 0%.
- Enhanced the progress indicator to better reflect the actual progress when importing a Mentor Xpedition design.
- Disabled unnecessary processing to significantly improve performance when importing a Mentor Xpedition design.
Power Analyzer by Keysight:
- Surface layers were incorrectly being included into the internal layer max. current density simulation, causing the specified limit to be exceeded and the analysis to therefore fail.
- It was not possible to see all Pin Loads in the Load Properties dialog, as there was no ability to scale the dialog or scroll the listing.
- If more than 32 loads were configured for a single source, the error “Exception has been thrown by the target of an invocation. —> System.InvalidOperationException: Sequence contains no elements” would be encountered.
- When viewing the details for any network in an analysis report, the value presented for the ‘Power Consumption for This Network’ field was always displayed as “0 Watts”, instead of the actual power consumption.
- When viewing an analysis report, the value for ‘Max Via Current Density’ (in the Global Settings section) and ‘Max Current Density’ (in the Failed Via Summary) was always displayed as “0 A/mm^2”, instead of the value defined in the configuration.
- When configuring the load properties for a load component, Altium Designer would freeze if the Total Load Current was set lower than the Pin Load Current.
- If a layer was renamed for a board in the Layer Stack Manager, an error would be encountered when next attempting to open the design’s associated Power Analyzer Keysight document (<ProjectName>.pdnaK).
