I recall that one. It has some logic-race bugs.
May well be. Why don't you enumerate them? Be precise. This is
supposed to be what this group is all about.
I did, back when he first posted it. Any non-trivial clocked logic with multiple
async inputs will probably have bugs. Proving that it does not is a lot more
work than just doing it right from the start.
(1) You just said "buggy" and "race conditions", but no particulars;
but that's you style, criticism with no real content. And when
pressed for details you go silent... which is when you're at your best
:-}
But you "don't do digital."
(2) But I do... remember, I re-did all of ON Semi's 74HCxxx stuff a
while back.
Synchronous logic is, indeed, convenient. Requires almost zero brain
power to avoid race issues.
Async... now that takes some skill... just today finished a fault
catcher that's fully async.

I love to cook with wine. Sometimes I even put it in the food.
