Article note: Handy. I was contemplating a problem that \"throw a tiny parallel PROM or 16v8 at it\" seemed like \"the right way\" the other day and noticing the options had contracted considerably, nice to see them documented.<\/div>

Do you speak GAL? [Peterzieba] does, and has pulled together a collection of documents and tools so that you can too<\/a>. There’s a dividing line in electronic engineering education, between those who were taught about FPGAs, and those who weren’t. Blurring that line slightly is gate array logic (GAL). These devices were a preceursor to the FPGA, with a much simpler structure, and usually in those days UV-erasable in the same manner as an EPROM. And oddly enough, they, or at least their successor compatible parts, are still available, and as handy DIP devices that talk to 5 volt logic.<\/p>\n

The guide goes into detail about the parts, the terminology surrounding them, and the CUPL language which raises a few memories for us. There are several possible workflows, including for those not faint of heart, the possibility of writing a fusemap by hand. We’re impressed by that one.<\/p>\n

If these devices interest you, our colleague Bil Herd wrote a two-part guide (part one<\/a>, and part two<\/a>) which should answer your questions.<\/p>\n

Thanks [Bjonnh] for the tip!<\/p>\n
