Synopsys PrimeTime - Required Arrival Time

[tonelow]

Hello,

I have spent some time trying to figure this out. I am synthesizing and analyzing circuits with a typical Synopsys Flow.
I am doing post-layout timing analysis with PrimeTime and have spent a bit of time digging through the manual trying
to find something that is seemingly obvious. Is there a builtin command to report the required arrival times at each cell?
Or is it necessary to write a script to do this? It is my understanding that in a typical STA engine, worst-case arrival times
are propagated from the PIs to POs and then required arrival times are propagated in the opposite direction from POs to PIs.
I kind of assumed that reporting RAT for each node would be a basic command. Any insight to this would be very helpful.
Thank you!

Best,
Tony

your question is not clear , what exactly you want .. you talked a couple of topics here.

there are command which give you the reports ... in the form you want.

if you do report timing -numpath 100 , then it will give 100 worst path (setup) .. similarly if you type report timing -from [cell instance/name] -numpath 1000 , then it should give almost all path on that particular cell ..

you can try different option in report timing ..
