Does anyone know of any modern-ish (VHDL, Verilog, etc) design software that will work with 1990's vintage CPLDs like the AMD/Lattice MACH110? The only thing I've found so far is ~1993 MACHXL from AMD, which is a DOS program that installs from floppy images (sort of, anyway.) And it's essentially "advanced PALASM."
I've got them current and "classic" IDEs from Lattice, but they don't seem to go back as far as MACH1/2 (even though they DO support simple GALs like 22v10. Sigh.) Is there some way to add older chips to these?
