WebFalse path and multicycle paths are the timing exceptions in the design. False paths: Paths in the design which doesn't require timing analysis are called False paths. These paths … WebNov 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 ...
