What's the approximate cost of those scan chains. I.e. if we were toI wouldn't matter because it wouldn't be testable in production.
take an existing working design and replace all the "flip-flop with
scan-chain" with "plain flip-flops", how much smaller would the
resulting chip be, how much faster could it run, and how much less power
could it consume?
