In this article, the effect of Instructions on the delay of the execution unit of the pipeline processor is examined. Better than Worst-Case scenarios set the clock frequency faster than the nominal one and avoid potential timing violations. In this work, the effective parameters that could predict timing violations in the processor are examined. It will be shown among different parameters, in most of the applications, Program Counter is the most accurate violation predictor. Time Borrowing is used as prevention mechanism. This mechanism reduces the performance overhead of preventing errors to zero.
