4.1i Timing Analyzer/TRCE (Trace) - The unconstrained path report contains constrained paths

Description


General Description:

A number of paths that are covered by constraints appear when I produce an unconstrained path report. Which report is correct?

Solution


If constrained paths appear in the unconstrained path report, this is simply a reporting error -- the PAR analysis is working successfully.



If a path appears under a constraint, that path is already covered and may be safely ignored in the unconstrained path report.
