So the simulator we've been using is GHDL. Its repository is at:


And its mailing list is at:


That said, I have never successfully managed to build this thing from
source (too many prerequisites), and I don't know where to find a
current prebuilt binary. It doesn't appear to be in the Ubuntu 14.04
apt-get repository either.

Below is the message Geoff Salmon sent in September of last year on how
to use it, which does not seem to cover how to bulid it...



Hi all

The attached tarball contains some VHDL and a Makefile which show how 
you can simulate with GHDL [http://home.gna.org/ghdl/] and view the 
resulting waveforms in GTKWave [http://gtkwave.sourceforge.net/]. See 
the README for more info.

If you're starting to look at VHDL, I think being able to run it and see 
the results is essential. Once you've got GHDL and GTKWave installed, 
hopefully this will make that step easy. Let me know if you have any 
questions or encounter problems.
