Re: Timing report
I dont have experience in SOC encounter. After CTS, the clocks need to set as propagated clocks in Synopsys tools. Like, Set_propagated_clock [all_clocks]. Check the same in SOC encounter also. If you have some ting like, Ideal net attributes on clock related cells, try to remove it and check timing report.
To find out the reason in synopsys tools, we have command called, report_delay_calculation -from <> -to <> to cell. Which will show the reason for Zero delay or wrong delay calculation. Check the same in SOC encounter. Check the attributes on the clock network.
