VHDL simulation on MacOS X

You are viewing an old revision of this post, from October 26, 2013 @ 09:41:23. See below for differences between this version and the current revision.

While actually programming a CPLD is not possible on Mac, you’re able to compile and simulate: I installed GHDL from here:

http://ghdl.free.fr/site/pmwiki.php?n=Main.Download

ghdl lets you analyze and elaborate a VHDL design + test bench from the command line. Then you can view the simulation as waveforms with gtkwave:

http://gtkwave.sourceforge.net/gtkwave.zip

Documentation for ghdl (once installed)  is in file:///usr/local/ghdl/doc/ghdl.html

this guide was also useful for me to set things up: http://dcse.die.upm.es/Grupo42/ManualGHDL_v1.1.pdf

see the script ./simulate_Ram_control.sh in the synkie svn repository for how to invoke the simulation from the command line.

I commented out the line that launches gtkwave because you have to launch gtkwave only once, then when you recompile a corrected version you’ll only have to select “Reload Waveform”  from the Edit menu. I’m pretty sure this same thing should be possible to do in ModelSim but I just couldn’t figure this shit out.

But cow can actually just double click on the generated .ghw file to see the waveforms.
