Sigasi Studio 4.3

Released on 2019-03-21

We are proud to present the Sigasi Studio 4.3 release: More autocompletes, Quick Fixes and lots of UI improvements.

Read below to find more details.

Autocomplete for include directives (Verilog)

When you trigger autocomplete inside the double quotes of a (System)Verilog include directive, Sigasi Studio will offer you include paths matching the current prefix. This makes it a lot easier to get the paths first time right.

Quick Fix to Suppress Warnings

Warnings now have a Quick Fix to automatically add the @suppress comment. The Quick Fix automatically adds the warning’s message. This makes sure the correct warning is suppressed (even when the code changes). We recommend to also add an explanation with the reason why you suppress the warning.

Dark theme

We received a lot of feedback asking for better Dark Theme support in Sigasi Studio. So in Sigasi Studio 4.3 we put a lot of effort in making sure all views and features look nicer with Dark Theme enabled. All graphics (Block, State Machine and Dependency diagrams), the Documentation View, Prepocessor View, the VUnit Console, … are reviewed and improved.

We also reviewed and polished our icons to look nice with a Dark Theme.
