Hi,

    Is there anyway to do conditional setup and hold violation checks.

I have flop and D is driven by andgate with 4 inputs. I would like to check setup and hold violations only during transitions on 3inputs but exclude timeing check when there is transtion on 4th input. Is there any method to do this?  i mean we can do it by changing setuphold statement but i would like to do it from testbench or from tool like

we exclude timing of instance by mentioning it in tfile...

 

regards
