Abstract:
A test system comprising:a test pattern generator adapted to store a series of predetermined test vectors and, for at least some of the test vectors, an associated signature, and adapted to output a test vector to a â€œgoldâ€  standard unit and a unit under test when a gating signal is applied thereto; a signal generating circuit adapted to receive output signals from the gold unit, the output signals forming a series of result vectors, and adapted to output a signature for at least some of the result vectors; a match detection circuit adapted to receive a signature from the test pattern generator and a corresponding signature from the signal generating circuit, and adapted to output the gating signal when the signatures match; and a comparator to compare the output signals from the â€œgoldâ€  standard unit and output signals from the unit under test.
