RES-50010: Reset Synchronizer Chains with Constant Output
Description
Violations of this rule identify asynchronous reset synchronizer chains that are fed by a constant data signal with the same value as what it is reset to. Such a chain is therefore inactive.
Recommendation
Feed the head register of reset chains by a constant of an opposite value to the reset value of registers in the chain.
Severity
Low
