Hi,

Anyone can help me understand how PrimeTime calculate cell delay value use CCS Timing model?

In library CCS Timing model we only have current value so how PrimeTime use these value to calculate delay it reports? Any equations we can have to re-verify the delay value through these lib current value?
I am looking for many documents and articles but no real answer... Most of them just talk about the theory of CCS no specific calculation.

Thanks a lot!
 

You can try command "report_delay_calculation" in PT
