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.
