Most of the metastable times are quite short, although the probability of having a long time is non-zero. Theoretically you could have a metastable time on the order of seconds, although the …

2018年6月24日 · \$\begingroup\$ As an example, back when I was doing chip design I 'owned' metastability, all the clock crossings, we did the math, figured out the chances of synchroniser …

Edit: Here is a scope trace showing the output of a flip-flop going through a metastable state, with the exit from the metastable state taking a random amount of time: Picture taken from W. J. …

2016年6月3日 · I mean, if the first flop of the Synchronizer becomes metastable, then the second flop of the Synchronizer will have different readings and it will propagate this reading up to the …

What happens in your picture is that the arriving signal is initially metastable. This generally means the signal is oscillating around a voltage that neither can be interpreted as 0 or 1. If it …

2016年5月17日 · If it does go metastable, it resolves itself within some amount of time — the probability of remaining metastable after time t is an exponentially decaying function of t. The …

2016年6月2日 · Second, the metastable (pseudo-mid-rail) value from bq1 could be unlikely (or optimised to avoid) to be in the window that would also cause bq2 to be metastable - but its …

2021年8月13日 · But if it's high speed design like GHz order destination clock, you would need more than 2 flops on the synchronizer to be on the safer side. Possibility is that second flop …

These metastable equilibrium lasts for more than 130ps, with the V(out) voltage of approx. 0.544V. The process is straightforward, but tiresome and long: the timestep must be very …

2021年12月3日 · The underlying idea is that the first stage may run into metastable state due to the insufficient setup and hold time of the input signal, but the second stage sees the output of …
