TMC-20205: Endpoints of Paths Failing Setup Analysis with Explicit Power-Up States that Restrict Retiming

Description

Violations of this rule indicate endpoints of paths that fail setup analysis with explicit power-up states that might restrict retiming. A path might not be fully optimized by the retimer if either of its endpoints has a power-up state. Refer to Initial Power-Up Conditions in the Intel Hyperflex Architecture High-Performance Design Handbook for more information.

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 applying the IGNORE_REGISTER_POWER_UP_INITIALIZATION ON setting to registers or their hierarchy to allow retiming optimizations to improve performance.
