TMC-20205: Setup-Failing Path Endpoints with Explicit Power-Up States Can Restrict Retiming

Description

A violation of this rule indicates setup-failing path endpoints with explicit power-up states that might restrict retiming. A setup failing path might not be fully optimized by the retimer if either of its endpoints has a power-up state. See Initial Power-Up Conditions - Section 2.2.7 for more information.

Recommendation

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

Parameters

maximum_setup_slack: A violation is reported for timing paths that have a setup slack below the value of this parameter.
