Abstract
An approach is provided in which an information handling system executes multiple timing constraint sensitivity tests on a circuit model using a first signal arrival time and generates multiple test results. The information handling system compares the multiple test results with a pre-determined probability threshold and, in response to determining that an amount of test failures included in the multiple test results meets a pre-determined failure probability threshold, the information handling system computes a timing constraint sensitivity of the circuit model based upon the first signal arrival time. The information handling system compares the timing constraint sensitivity against a characterized sensitivity generated by a software modeling system and, when the timing constraint sensitivity does not match the characterized sensitivity, one or more of the software modeling system's modeling parameters are adjusted, causing the software modeling system to generate a changed characterized sensitivity of the circuit model.
