"All" that is needed is for someone with a bit of C++ experience, and knowledge of Quine-McClusky (sp?) to fix up Steve's ipal code. The only part that it does not do is convert the netlist to sum-of-products (or product-of-sums; I forget which the PALs implement natively), and then fill in the fuse map with the combinational logic. ipal takes care of writing the JEDEC file, allocating the registers, etc. I looked at this in depth a while back, but a) I'm not so good with C++ and b) I don't quite understand the workings of QM well enough to reimplement it in the framework of someone else's code. One could try to reimplement PALASM, but I think you're faced with the same logic minimization problems-- so you might as well start with Verilog as the HDL, since the framework is already there. -- - Charles Lepple
