"WebPerforming timing ECO (Engineering Change Order): Multibit flops have a common clock pin and test pins. Performing ECO on these pins would be difficult if we are targeting only one bit out of 2 or 4 bits. For example, if we want to adjust the clock skew at the ECO stage to recover any timing violations for a particular bit, the additional skew ... " - Dff timing
