I would like to become familiar with CPLD's such as the ATF15xxAS. I've done some research but am still unsure what the technique is for designing the desired logic and outputting a file which I presume I would then use with my EPROM programmer? Is that how it would go? Would it be a JEDEC file such as with GAL's? Really though I can't figure out what software to use. It looks like MicroChip's ProChip Designer might be it but I haven't received a response to my license request from a couple weeks ago (I'm not faulting them given the current situation). At this point I figured perhaps I should stop and ask the community for advice. Basically I have three basic logic IC's and a GAL that I would like to try to consolidate into one chip. This is hobby stuff in case that's relevant.
