Что нового в Altium Designer

Wire Bonding Improvements

Support for Panelized PCBs

Bond wires and die pads are now displayed when viewing a panelized PCB document in 3D.

Also, generation of a Wire Bonding Table Report from a panelized PCB document is now supported.

For more information about panelized PCBs, refer to the Board Panelization page.

A New Query Keyword for Detecting Bond Wires

A new IsBondwire query keyword (PCB Object Type Check) is available, when constructing logical query expressions to use in the filtering of objects in a PCB/PcbLib or in the scoping of a design rule.

For more information, refer to the Object Type Checks page.

Harness Design Improvement

Ability to Place a Harness Bundle Break Point

A break point, which is used as an indication that the bundle is Not to Scale (NTS), can now be placed on a harness bundle in the harness layout drawing (*.LdrDoc). The bundle will display a break symbol in the middle of its longest segment as shown in the first image below, and the properties will display the Drawn Length, which reflects the length of the bundle as drawn in the design space. Typically, the physical bundle length will be considerably larger. When the Length field (actual physical length) is set and it differs from the drawn length, the bundle will display a break symbol at the center of its longest segment to indicate that the bundle is Not to Scale (NTS). To place a break, enable the Add Break Symbol option in the Properties region of the bundle properties. Harness coverings that cover a harness bundle with a break point will also display the break in the same location. If the harness covering ends at the harness bundle break point, the covering will be drawn slightly longer, as shown in the second image.

For more information, refer to the Creating the Harness Layout Drawing page.

Data Management Improvement

Ability to Preserve Lifecycle State When Synchronizing Components

With this release, you now have the ability to preserve the lifecycle state when performing component synchronization between your Workspace and your component database using Altium Designer’s Components Synchronization feature.

This ability is facilitated by a new Preserve lifecycle state option. With the data source (table) selected in the Components Synchronization Configuration document (*.CmpSync), this option can be found in the Advanced section of the Properties panel.

Note that this ability is available for those who are assigned Allow to skip lifecycle state change for new revisions operational permission (learn more about Setting Global Operation Permissions for a Workspace).

For more information about the Components Synchronization feature, refer to the Component Database to Workspace Data Synchronization page.

Features Made Fully Public in Altium Designer 26.2

The following features are now officially Public with this release:

• BOM CoDesign - available since 25.1

• Excluding Supplier-related Fields from BOM Comparison Result - available since 26.1

PCB Design Improvement

Solder Mask Expansion Rule Default Now 0 Mils (Open Beta)

Observing the IPC-7351B standard in relation to padstack defaults, where the solder mask openings are typically a 1:1 ratio of the land size, the values for the Solder Mask Expansion rule (in PCB documents) and rule-driven solder mask expansion (in PCB library documents) are now set to 0 mil by default (previously 4 mil).

For a PCB library (*.PcbLib), support for these new default values are at the library level, inherited by all component footprints created therein. The same PCBlib will show, for all object rule-driven solder mask expansion, 4 mils expansion when opened in a previous version of Altium Designer and 0 mils expansion when opened in this release and later, as shown below for a pad object.

For a PCB document (*.PcbDoc), all existing Solder Mask Expansion rules store their initial values. The default values used for any newly created rule are determined by the version of Altium Designer where that rule was created and will not change while opening in another version of Altium Designer. Therefore, the default is 4 mils expansion when created in a previous version of Altium Designer and opened in any other version, and 0 mils expansion when created in this release (or later) and opened in any other version, as shown below.

A newly created Solder Mask Expansion design rule in the Constraint Manager.

For more information about the Solder Mask Expansion design rule, refer to the Mask Rule Types page.

Constraint Manager Improvement

Added Ability to Filter Classes

An ability to filter classes has been implemented in the Constraint Manager's Clearances view to leverage your work with a large number of classes. This enables the construction of filters (or groupings) of classes to allow switching between, and working with, focused sub-sets of the clearances matrix.

Use the  button at the top right of the Clearances view to access a pop-up from where you can create, edit, remove, and enable/disable filters.

For more information about working with the clearance matrix, refer to the Defining Design Requirements Using the Constraint Manager page.

Draftsman Improvement

Enhanced DXF Import to Draftsman Documents (Open Beta)

This feature adds support for importing DXF files version R12 and later into manufacturing drawing documents (*.PCBDwf, *.HarDwf, *.MbDwf). Importing DXF files including splines is also now supported.

For more information about importing DXF files, refer to the Draftsman Placement & Editing Techniques page.

Wire Bonding Improvement

Bond Wire Primitives in Panels

Bond wires are now presented with the correct type (Bond Wire) in the following places:

• The Primitives region of the PCB panel, with a selected component in Nets mode

• The Component Primitives region of the PCB panel, with a selected net in Components mode

• The PCB Library panel, with a selected footprint.

Selecting a bond wire primitive will select/highlight that bond wire within the design space.

In addition, a corresponding Show Bond Wires option is now available on a region's right-click context menu, for toggling bond wire visibility.

For more information about wire bonding, refer to the Wire Bonding page.

3D-MID Design Improvement

3D-MID Design Rule Check (Open Beta)

This release provides batch Design Rule Checking (DRC) for Width, Clearance, Length and Matched Lengths rule violations, in respect to routed tracks on your 3D substrate. Note that while a generated DRC report will provide information for all of these checks, only clearance violations will be highlighted within the design space.

For more information, refer to the 3D-MID Design page.

Multi-board Design Improvement

Ability to Define 'Termination Type' for Harness Entries

The Termination Type for a harness entry can now be defined on a multi-board schematic. The termination types available are:

• Connector – the standard option used when connecting to a mating connector on the PCB. It typically involves standard board-mounted connectors.

• Crimps/Ferrules – individual wires are terminated with crimps or ferrules before being inserted into the connector on the PCB side.

• Wire termination – wires are blunt-cut at the harness end and either screwed down or soldered directly to the PCB. This is common with direct wire-to-board connections such as with some JST connectors.

The information is reflected in the properties for the selected harness entry and the corresponding module entry.

For more information about working with connections on a multi-board schematic, refer to the Working with Connections page.

Harness Design Improvements

Enhanced Synchronization of Wires

Harness wires connected with a wire break are now recognized even if they have different Design Item IDs. In addition, all wire segments with the same designator connected by the same wire break are now compared (for part number, comment, color, and all parameters). If any differences are found, the Mismatched parameters in connected wire segments violation is reported. A warning also appears in the Properties panel of the wire and wire break signifying that a conflict has been detected between the parameters. Click Synchronize within the warning to open the Conflict Wire Parameters dialog, which gives you the choice of which parameters to use for the wire segment.

Ability to Place a Covering over a Junction Point

You can now apply/extend a harness covering over a junction point (a connection point in the layout drawing where two or more bundles come together) on the harness layout drawing (*.LdrDoc). This removes the need to have separate harness coverings between junction points in a section that contains several connectors.

In addition, the start of a covering is now taken as the left-most, top-most point of its path, and that path now includes only the bundles the covering lays on.

For more information, refer to the Creating the Layout Drawing page.

Quantity Field in BOM Changed to 'As Required' for Certain Objects

Wire, cable, and harness coverings are length-based objects and the value is displayed in the Length field. To avoid confusion, the Quantity field for wire, cable and harness covering entries in a Bill Of Materials table and an ActiveBOM document in a manufacturing drawing document (*.HarDwf) is now As Required. 

For more information, refer to the Managing Your Bill of Materials (BOM) with ActiveBOM page.

Improved Pin Grouping in Wiring List

Pin grouping in a wiring list that is placed in a harness manufacturing document (*.HarDwf) has been improved. Starting with this release, automatic grouping is applied to the connector with the most wires, and all of its cavities are correctly grouped in the From column of the wiring list as shown in the image below.

Excel Workbook for Harness Manufacturers

Added the ability to generate, through an Output Job, a single Excel Workbook containing data for use by harness manufacturers. To facilitate this, a new outputter – Manufacturing Data – is available under the Report Outputs section.

The generated Workbook includes four distinct sheets:

• Bill of Materials – useful for quick quote generation.

• Wiring List – for use with wire processing machines.

• Labels – a summary of the physical labels to be printed for harness bundles, for use with Zebra or other printers.

• Coverings – a summary of the coverings to be applied over harness bundles.

For more information, refer to the Preparing Reports page.

Platform Improvement

Switching to .NET 8

With this release, Altium Designer switches from using .NET 6 to .NET 8. This is bundled as a part of Altium Designer and enables it to take advantage of later functionality and developments with .NET, including general performance enhancements.

For more information, refer to the System Requirements page.

WebView2 (Open Beta)

Starting from this release, WebView2 is used for browser-related elements within Altium Designer (e.g., the Home page). This delivers access to the latest web browser engine within Altium Designer, just by updating Windows.

Data Management Improvements

Ability to Copy Workspace Project Using Process Workflow

Added support for making a copy of a Workspace project using defined (and enabled) process workflows. When a Workspace project is opened, right-click the project entry in the Projects panel and select an activated process definition (that is part of the Project Creations theme) from the Make a copy of the managed project sub-menu to start copying the project in accordance with the underlying workflow for that process.

For more information, refer to the Process-based Project Creation page.

Added Ability to Preserve Lifecycle State when Releasing Models

When releasing a new revision of a component model (schematic symbol, PCB footprint, simulation model, or harness wiring) to the connected Workspace, you can now preserve the model's current lifecycle state.

Note that this ability is available for those with assigned Allow to skip lifecycle state change for new revisions operational permission (learn more about Setting Global Operation Permissions for a Workspace).

For more information about editing Workspace content, refer to the Creating & Editing Content page.

Design Review Comment Links

When a comment is added as part of a design review, a link to that review (From <DesignReviewName>) is now presented within a corresponding entry in the Comments And Tasks panel and the contextual commenting window for that comment (within the design space). Click the link to open the review's Overview page in a new tab of your default browser.

For more information about document commenting, refer to the Document Commenting page.

Support for Additional Unit-aware Data Types

When defining a user parameter as part of a component template in a connected Workspace on the Altium Platform, the following additional unit-aware data types are now supported:

• Area (mm²)

• Bar (bar)

• Bit

• Candela (cd)

• Decimal

• Integer

• Joule (J)

• Lumen (lm)

• Millimetre (mm)

• Pascal (Pa)

• Pounds per square inch (psi)

• Rotations per minute (rpm)

• Siemens (S)

• Tesla (T)

Parameters using these new unit types are supported in various areas of the software, including the Components panel, the Component editor (in both single and batch editing modes), and by the Library Importer and Components Synchronization feature (in the Parameter Mapping section of the Properties panel).

For more information about the unit-aware component parameter data types, refer to the Component Templates page.

Ability to Sync Part Choices when Using Components Synchronization

The ability to define and sync part choice information using the Components Synchronization feature and its related Components Synchronization Configuration document (*.CmpSync) has been added. Control of the synchronized parameters is available in the Part Choices Mapping region of the Properties panel when a table is selected in the document. Use the buttons to add and remove part choice parameter pairs (Manufacturer / Part Number) and drop-down menu options to define the mapping. When mappings are defined, the corresponding parameters appear under Part Choice n columns in the document grid area.

For more information about the Components Synchronization feature, refer to the Component Database to Workspace Data Synchronization page.

New Warning Regarding Problems Connecting to a Workspace

If there is an issue connecting to a Workspace and the latest VCS states of project documents are not able to be refreshed, the Refresh VCS Statuses control (with associated tool-tip warning) now appears next to the project entry in the Projects panel. Once connection resumes, click the entry to bring the VCS states back into sync and to see the latest changes.

For more information about indicating document status, refer to the Managing Project Documents page.

BOM CoDesign Improvement

Excluding Supplier-related Fields from BOM Comparison Result (Open Beta)

When comparing an ActiveBOM with a selected Managed BOM by using the BOM CoDesign feature, when the advanced setting is disabled, supplier-related data (Supplier and Supplier Part Number parameters) is excluded from the Differences section on the Related BOMs tab of the Properties panel when it has been accessed from an ActiveBOM document.

For more information about exploring comparison results, refer to the BOM CoDesign page.

Import/Export Improvements

Enhanced Allegro Design Imports

All configuration files that are required are now included in the Allegro2Altium.bat file, a batch file included in your Altium Designer installation and used to convert an Allegro binary (*.brd or *.dra) file to ASCII format (when such a design/library is not on the same PC as Altium Designer). Therefore only the bat file is required for the import and no additional files.

For more information about exploring comparison results, refer to the Importing a Design from Allegro page.

Support for Component Alternative Views from xDX Designer Designs

Alternate view modes for components are now supported, in both generated schematic and schematic library documents, when importing an xDX Designer design.

For more information about exploring comparison results, refer to the Importing a Design from xDX Designer or DxDesigner page.
