4.1i Timing Analyzer/Trace(TRCE) - PAR reports timing errors while Timing Analyzer/TRCE does not.

Description

General Description:

Par reports timing errors while trce doesn't. The timing simulation works fine so trce looks correct. Timing violations may also not be reported.

Solution

The skew calculation can be performed incorrectly when clocks are multiplexed, and the skew between two clocks is different.

This is fixed in the current version of the software. The first version containing this fix is 4.2i.
