> synchronous logic design because everything happens in parallel, but it's a set of well-understood building blocks. Whereas asynchronous design is just entirely free of familiar reference points and there isn't quite the same set of standard idioms....Yes, you get rid of setup/hold violations, but you're going to get a whole new class of problems with the addition that "timing closure" is now a moving target. Sounds like the argument about the problems and differences typed/untyped programming languages. One set of problems is solved with typing at the cost of linguistic expressiveness due to lacking and/or cumbersome type systems. I'm thinking async hardware is the typeless of HW designs, but that also takes off the safety guards used from years of experience in synchronous design.
