8.1i Timing Analyzer/Constraint - OFFSET constraint specified with no PERIOD constraint causes core dump during advanced analysis

Description

When trying to perform an advanced analysis on a design with no PERIOD constraint and only an OFFSET constraint specified, the Timing Analyzer core dumps.

Solution

All OFFSET constraints need to be relative to a clock.

You can work around this issue by specifying a PERIOD constraint so that the OFFSET can be relative to a clock. This will prevent Timing Analyzer from core dumping during advanced analysis.

For additional information, see (Xilinx Answer 5489).

This issue will be addressed in a future release.
