Abstract: A computer-implemented method, and system, for detecting modification of a semiconductor device includes generating and applying an exhaustive first set of patterns to a netlist golden model of a golden device. The exhaustive first set of patterns is developed by a pseudorandom number generator. Applying the patterns to stimulate the device produces a first response serial bit stream in relation to logical composition of the golden model. A signature analyzer compresses the total output to provide a first cyclic redundancy code or answer. The same exhaustive set of patterns can be provided to stimulate the model of an unknown device. The unknown device is shown to be identical to the golden device if its answer matches that of the golden device and modified if its answer does not match that of the golden device.
