NettetUncertainty (clock uncertainty) models the maximum delay difference between the clock network branches, known as clock skew. But it can also include non-ideal behaviors of clock like clock jitter and margin – set_clock_uncerainity -setup Tu [get_clocks ] Example – create_clock -period 5 [get_ports CLK] Nettet2. jan. 2024 · Check if HOLD critical paths have a big clock skew. If so, fixing clock skew can help avoid a large number of buffers or inverters from being added on data paths to fix hold violations. Check set_clock_uncertainty is not too pessimistic, as this will make the hold violations worse. If using OCV, check setAnalysisMode -cppr both is set.
