[SOLVED] Clock Gating for synchronizers

[sharath666]

Hi all,

Could you tell me why do some people avoid clock gating for synchronizers while enabling it for the rest of the design?

It is mainly due to possibility of occurrence of metastable state..

 

[sharath666]

Could you kindly explain why is the possibility of metastability occurring more here?

 

[Vengateswaran]

The changing clock level may cause this state which can lead to data corruption.. In all the cases, handshaking will be followed and so there is no possibility or less probability of data corruption...

Thank You...
