Ha! Karnaugh maps don't scale very well, so when I did this I switched to Quine-McCluskey when the glue logic got big. And often it was easiest to implement glue logic with ROM (treating address lines as inputs and data lines as outputs) rather than with explicit gates. What I miss about VHDL is the ability to design the full logic as a schematic. Schematics were our bread and butter back then.
