Abstract
A test circuit is adapted to test circuits having a high-frequency clock signal. The test circuit is positioned between a conventional tester and the circuit to be tested. The test circuit includes a frequency multiplication circuit which multiplies the clock signal of the conventional tester to produce a high-frequency clock signal. The test circuit also receives control signals from the conventional tester. The control signals are output to the circuit to be tested via a bus.
