I don't know, what are the exact commands to use in SOC encounter per se.. but for checking the QOR of CTS you have to check the local skew, global skew,insertion delay, clock tree cell count,trace the clock tree structure for the top ins delay sinks.

Quality of CTS result from Soc Encounter's report files.

you can check the reports generated by cts engine
check for each clock:
what is the skew for each clock: generally trigeredge skew is the considered skew for each clock.
max_delay or latency
no. of buffers inserted.
no of levels in the clock treee.

Hi

Thanks for your reply.

I have one more doubt....
What will determine the number of levels in a clock tree while doing CTS??
