5.1isp3 Timing Analyzer/TRCE - Invalid hold violations are reported, but no paths are listed in the error report

Description

General Description:

When I run my design through PAR, the PAR report states that I have several constraints that were not meet. I then run a timing report, but no errors appear and nothing is highlighted in red. When I scroll through the report, I see several hold violations on multiple constraints. Why is this happening?

Solution

PAR and the timing process are reporting false hold violations.

This issue was fixed in the 5.2i software release. To see the actual failing paths, run the design through PAR using the 5.2i software.
