Introduced is a self-driven test point structure which permits at-speed, on-chip, non-scan, sequential testing using parallel pseudorandom test patterns applied only to the primary inputs of the circuit under test. The test network is unique in that aside from a test mode flag, all I/O signals needed for test system operation are tapped from within the circuit itself. High single stuck-at fault coverage is achieved for a number of ISCAS-89 benchmarks.
