Sigasi Visual HDL 2025.3 in Eclipse

Final Release

This is the final feature release for Sigasi Visual HDL in Eclipse. After a year of ramping down development on Eclipse, we highly recommend you to now transition to SVH in VS Code. From now on we will focus exclusively on SVH in VS Code for your benefit. Please do not hesitate to get in touch with either our Sales Team or Support Team if you need any help transitioning to VS Code.

Eclipse bump

The Eclipse version was bumped to 2025-06.

Documentation Export

To ensure stable documentation, the Sigasi version and timestamp are no longer included by default. Instead, this can be enabled via two options.

Once state machines become large, it becomes difficult to visualize transition conditions and comments yet keep the diagram comprehensible. To assist you in those scenarios, there is now a State Machine Transitions table. It is included in the Documentation View and generated documentation.

A separate view is also available, but only in SVH in VS Code. To enjoy it, consider transitioning now.
Our Sales Team or Support Team will be happy to assist you with the transition

Library Mapping Guidance

A project is made up of files that are mapped to a library or included by one that is. To unlock Sigasi’s full potential ensure that your library mapping is correctly set up.
