4.1i Trace (TRCE)/Timing Analyzer - An incorrect period requirement is used for cross-clock domain paths for multiple constraints

Description

General Description:

An incorrect period value is used for paths that cross clock domains. (This only occurs if either the source or destination register is covered by multiple PERIOD constraints.) How do I avoid this?

Solution

You can avoid this situation by eliminating the extra PERIOD constraints.

This issue was fixed in the 4.2i software.
