set_clock_uncertainty

As far my knowledge, the uncertainty means "Skew + Jitter".

Now the question is, Are there any more parameters which will gets added into this?

Click to expand...

yaa..uncertainty also include margin..skew+jitter+margin for setup and skew+margin for hold
 
it may also include clock OCV (on chip variation) margin and crosstalk margin
 

Thanks alot Sharif.

Pradeep, OCV margin is set by using set_timing_derate command and not with uncertainty.
 
you cannot Derates through clock uncertainity. clock uncertainity covers only Clock jitter and Clock skew
