xact 6.0.1: Discrepancy between Timing Analyzer and Xdelay


General Description: whenever there is latch in the path, path propagation delay will be different under timing analyzer and Xdelay reports.


This is fairly common. The

reason for this is PPR is using its own algorithm to generate the

delays, and xdelay is using a different algorithm to generate the

delays. There is no way to fix the discrepancies. However, we have been

told that xdelay is the tools to believe. It is generating the correct
