Currently, only iverilog is supported.

A simple extension to run single file Verilog testbenches with GTKWave integration. Hassle-free, portable, easy to configure. Combines the best bits of everything out there.

This extension adds two buttons, which will appear in the titlebar of any Verilog file, and a status item positioned in the lower-right corner.

Be sure you have iverilog and gtkwave added to your environment PATH variable. If you need help, check out the installation guide here (and for Windows).

• verilog.gtkwaveWatchGlob: GTKWave will be summoned when a file satisfying the glob is created (glob is relative to the build directory).
• verilog.icarusCompileArguments: Arguments passed to Verilog compiler.
• verilog.icarusBuildDirectory: Build folder path relative to workspace root.
• verilog.icarusPersistentBuild: True if build folder should not be cleared before each compilation.

• icarusext.run : Compiles and runs current file
• icarusext.stop : Stops and kills any running processes.
• icarusext.tsizer : Obtains very rough estimates for logic components. Will run on these events:
  • window.onDidChangeActiveTextEditor
  • workspace.onDidSaveTextDocument
  • Status item click (will show modal in this case)
  • When command icarusext.run is run
