Since nobody else has mentioned it, Dr. Howie Johnson at one time
performed a Metastability lab demo in his class that was pretty cool. It
helped send home the importance of setup and hold requirements.

~15 years ago, when I was browsing for general digital logic books, I
used=20
Metastability as my test case. When I saw a book that looked
interesting, I=20
would open it to the index and look for Metastability. (This was long
before=20
Amazon, so you could find books in bookstores where you could touch
them.)
This was an amazingly quick way to evaluate a book. First, you got to
check=20
the index which I consider to be important. If I didn't find anything
then I=20
was suspicious. If I did, then I would go check out that section. I
think I=20
understand Metastability so it doesn't take long to find out if the
author=20
says something sensible.
Two books in my collection have good sections on Metastability:
High-Speed Digital Design: A Handbook of Black Magic
Howard Johnson and Martin Graham
Digital Design: Principles and Practices
John F. Wakerly
My opinions:
Anybody interested in SI should have a copy of "Black Magic". I like
the=20
style. Every time I open it to look up something I get suckered in just
rereading a section I've already read many times.
Wakerly is now up to the 4th edition (2005). Mine is a couple back. I
still=20
learn something every time I open it. I wish I had a copy many many
years=20
ago.
Both are a bit old, mostly using MSI (DIPs) as examples. But the ideas=20
haven't changed. I may be biased since I did a lot of work with MSI and
I=20
can easily relate to their examples.
