TMC-20204: Endpoints of Paths Failing Setup Analysis with Retiming Restrictions

Description

Violations of this rule identify endpoints of paths that fail setup analysis with retiming restrictions. A path that fails setup analysis might not be fully optimized by the retimer if either of the endpoints have a retiming restriction.

Parameters

Name Description Type Default Value Min Value Max Value
maximum_setup_slack Reports a violation for timing paths that have a setup slack below the value of this parameter. double 0.0    

Recommendation

Consider removing these retiming restrictions to allow retiming optimizations to improve performance. Refer to Retiming Restrictions and Workarounds in the Intel Hyperflex Architecture High-Performance Design Handbook for more information. Also refer to the Fast Forward Timing Closure Recommendations report for step-by-step suggestions for RTL changes and estimated performance improvement.
