Hi all,

I am looking to get the critical time of a circuit when specific set of inputs is given. Example, for a 4-bit multiplier, I want to check the critical time when multiplying 8'd4 and 8'd3, and when multiplying 8'd1 and 8'd2.

Is this possible with Primetime? Could someone guide me how to do this?

Thanks!

Not sure if "critical time" is a commonly understood technical term? By operation principle, timing analysis determines maximal combinational delay for all possible data values.

Thanks a lot!
I want to get the timing analysis (or combinational delay) for one specific set of inputs. Is this possible using dynamic timing analysis?
And could you help me with how to perform this using PrimeTime?

Thanks!
Regards,
Rohan
