I haven't looked yet, but how hard would it be to modify some of the supplied software tools so that they have no GUI but work in batch or scriptable mode? My use case is that, when I receive the answers to a project from my students, I want to be able to write a shell/Perl script to unpack their Zip files, extract their HDL files, move them into a directory with the original .tst and .cmp files, run the hardware simulator, and verify that their answers work, e.g. with the exit value from the simulator.
Would this be hard to do, and could the authors give perhaps a pointer on where to start the work? I'll be very happy to donate the changes back.
