Create clock source objects
WebSource latencies are based on clock network delays from the host clock (not necessarily the host pin). You can use the set_clock_latency -source command to override the source latency.. Figure 1 shows waveforms for the following SDC commands that create an inverted generated clock based on a 10 ns clock. WebJul 25, 2014 · • no_startpoint_clock: The timing check has no clock that launches the data at a startpoint latch. • no_constrained_clock: There is no constrained clock for skew or clock separation checks. • no_ref_clock: There is no reference clock for skew or clock separation checks. • no_clock: A minimum pulse width or period width check has no clock.
