It's not just die space, but much slower timing that's the main problem in most cases. At that point it's a lot better to iterate via hardware emulation.

- fuckyouriotshit 5y agoOh right. I didn't think about the extra time that signal propagation through a big ugly ROM would take. I my comment earlier about EDA tools being able to "simplify" the ROM into the die was probably a paraphrasing of what I was told about a tool. The tool (or workflow) allowed a designer to go from a working prototype microcode ROM to a hardcoded gate circuit (presumably by the same sort of process that one can go through to simplify a logic statement that is in disjunctive-normal form). This was information passed on to me second hand from quite a few years back now so I probably should've tried to look up some primary sources before writing my comment! Oh well.
