Sigasi Premium improvements

Mixed VHDL/Verilog projects

In Sigasi 2.24 it is now possible to enable both VHDL and Verilog support to a project. This allows to instantiate Verilog modules in VHDL code and vice versa.

Mixed language instantiations

Improved State machine viewer and block diagram view

  • The state machine viewer now shows the state assignment’s comment as text label on transitions.

Transition annotations in state machine view

  • The block diagram view now allows you to navigate to instantiated architectures
  • The block diagram view’s look is updated

Open entity declaration in block diagram

  • Note that we have also changed the navigation behaviour. You now have to double click if you want to navigate to the corresponding VHDL code.

Naming conventions

Sigasi Premium users can now configure Sigasi to check naming conventions while you type.

Formatter options

We added a preference page where you can configure a few formatting options: preserve newlines, upper case keywords, comment column.

Documentation Generator

Because a prototype is worth a thousand pictures, we have built our first version of the Sigasi Documentation Generator.

  • No special coding requirements: the plain comments in your code are extracted for the documentation. Comments next to a declaration or above a declaration form the documentation.
  • Live preview: you can see what the documentation will look like while you type your code and comments.
  • Fully hyperlinked PDF. If you save the documentation, you get a fully hyperlinked PDF.
  • All included. All documentation processing is done in Sigasi/Eclipse with no external tool dependencies.

All users can open the documentation view, but only Premium users can export to PDF.
