SYSTEM AND METHOD FOR EXECUTING FUNCTIONAL SCANNING IN AN INTEGRATED CIRCUIT ENVIRONMENT

摘要

An example method is provided and includes executing a functional test for an integrated circuit and observing a failure associated with the integrated circuit. The method also includes executing a functional scan mode in order to reproduce the failure associated with the integrated circuit. A functional state of the integrated circuit is locked when the failure occurs, and the functional state is subsequently recovered for a structure test for the integrated circuit. In more particular embodiments, particular states of the functional test are evaluated and compared against other states associated with a model circuit that did not experience any failure in order to identify a latest cycle of the integrated circuit that could trigger the failure and an earliest cycle of the integrated circuit that could observe the failure.
