Abstract
An improved approach is provided to implement performance checking. A check is performed as to whether two designs are equivalent without needing to analyze their outputs on a cycle-by-cycle basis, where the two designs are checked to see if they are equivalent on the transaction-level. Thereafter, the outputs for the transactions are analyzed relative to delay time periods, which allows verification and identification of possible performance issues and differences between the two designs.
