Metastability

thread248-5898

Metastability

Metastability

(OP)
Metastability is "cured" by a 2-3 stage shift register.

How is the probability affected, if there is a gate or a buffer between two FF=s which has delay and gain ? Formula ?

RE: Metastability

(OP)
1.) The given link contains only excerpts of a lecture.
2.) There is a formula to calculate the probability of metastability but it deals only with FF directly connected.
A delay should increase the probability of M. and a gain should decrease it. But how much???

RE: Metastability

Suggestion: Visit
http://edis.win.tue.nl/bibl.html
for essentially delay insensitive bibliography; however, some references are general. They might include both.
Incidentally, the web site in my previous posting gives a hint how to accomplish the delays, namely, over a counter of the clock pulses.
