Abstract
PURPOSE: To make it possible to generate identical patterns as many as repetitive operations when testing the logic of the integrated circuit of an electronic watch, etc., by making it possible to assign the number of times of repetition of each address to a pattern memory.
CONSTITUTION: In memory unit 1, test pattern information to be sent to tested body 6 is written to block 1a and a pair of repeat information on the number of times of repeatedly sending this information out and a jump instruction for the assignment of a next pattern are also written to block 1b at each address. The test pattern, read out from block 1a is waveform-converted by waveform converter circuit 2 and outputted to tested body 6, and digital comparator 7 makes a comparison to decide on the quality. At the same time, repeat information an jump information read out from block 1b are decoded by detection circuit 3, whose output operates address generating circuit 4 to sent next address assignment information out to unit 1, thereby performong the repetition of the test pattern or the jump.
