WebIt sounds like you're missing timing by -1ns postCTS. It would be useful to know, for your worst paths, whether this is caused by significant clock skew on a path ending on an ICG enable pin. If it is, then this script will give you insight into whether the tool could do a better job optimizing these paths preCTS than it can postCTS. WebJul 8, 2016 · Static Timing Analysis: Timing Paths (2) Clock Gating Path: Clock Path may be passed through a "gated element" to achieve additional advantages. In this case, characteristics and definitions of the clock change accordingly. We call this type of clock path as "gated clock path".

chevy traverse transmission recallWebNov 23, 2024 · A false path in VLSI is a timing path that may be caught even after a very long period and still provide the desired outcome. As a result, a bogus path does not need to be timed and may be ignored during timing analysis. To sum up, false paths are timing arcs in design where changes in source registers are not expected to be recorded by the ... goodwill pineville nc locationWebNov 14, 2024 · Timing values can be reported at any N sigma corner (since sigma is known). Usually, we report it at 3 sigma, as that implies 99.9% of the dies for that timing path will lie within 3 sigma (i.e only 0.1% of chips will fail for that path).
