It is claimed in the above-mentioned work that redundancy and masking techniques are ineffective in improving synchronizer performance due to metastable behavior. This claim is based on an input model that is not always valid, particularly in reliability analysis. The commenter points out the weakness in the assumed model and provides an alternative input model which can be used to analyze redu
