In short if your digital circuit is going to accept arbitrary patterns of inputs then there will be cases that cause it to produce non-stable output for arbitrary periods of time. Curse you, laws of physics.
- jacquesm 17y agoFrom that same wikipedia article: > Metastable states are believed to be inherent features of asynchronous digital systems and systems with more than one clock domain, but careful design can often make the probability of a system failing very small indeed. Which is more or less what I'm getting at, I wonder about the 'careful design' domain. Not perfect, but good enough to get the job done.
