ABSTRACT:
Communications equipment can be tested using a test pattern that is modified compared to, and more exploitive than, a standard test pattern. Test patterns can be employed that have lengthened or shortened consecutive identical digit (CID) portions, or that have lengthened or shortened pseudo random bit sequence (PRBS) portions. In some cases, PRBS polynomials are not re-seeded after each CID. Further, different order polynomials can be employed for different applications. Exemplary applications can include test equipment and built-in self-test capability for integrated circuits.
