GitHub Action to install NVC VHDL simulator.

See action.yml

- uses: nickg/setup-nvc@v1
  with:
    version: latest
- run: |
    nvc --version    # NVC binary added to path

Both Ubuntu and Windows runners are supported. The MSYS2 shell on Windows does not use the system PATH environment variable so you need to add it manually:

export PATH=/c/Program\ Files/NVC/bin:$PATH
