LNT-30021: Same Signal Source Drives More Than One Asynchronous Port of a Register
Description
Violations of this rule identify registers that have a common signal source driving into multiple asynchronous ports on the same register. This can result in signal races on the release of the asynchronous signals.
Recommendation
Ensure that the asynchronous signals that drive into each violating register are registered independently and do not have a common combinational logic source.
