While actually programming a CPLD is not possible on Mac, you’re able to compile and simulate: I installed GHDL from here:
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:
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.End of Ram Initialisation and first Read/Write cycles
