Web10 Apr 2024 · Using the set_clock_uncertainty command for that purpose wouldn't be a good idea. Ideal network latencies are not needed in P&R (after CTS stage) or post-P&R STA, but clock uncertainty is. If you define your clocks propagated in post-P&R STA, ideal network latencies are overridden 1 and actual values are used. This brings more flexibility.
