ABSTRACT:
A tester of circuit devices is disclosed which uses commercially available component parts but is capable of high performance testing of hierarchical memory cards requiring data pulses of variable pulse widths at high repetition rates. The tester includes two memories connected to respective shift registers which in turn, feed a multiplexer. The memories handle test timing patterns for respective halves of the basic clock test cycle and are interleaved in operation along with the shift registers. Two opposite-phased outputs of the multiplexer are applied through respective programmable delay networks and pulse generators to the set and reset inputs of a trigger circuit. The trigger circuit provides test data to a dedicated input pin of the device under test.
