Abstract

PURPOSE: To perform accurate logic test, by outputting the wait signal to the tester through the detection of logical judgement-disable-time point and stopping the test operation at the logical judgement-disable-period, in testing the logic circuit incorporating the unstable element impossible for the logical judgement.
CONSTITUTION: The multivibrator 1 is operated by applying the input and clock to the circuit to be tested including the monostable multivibrator 1, the output signal a of the multivibrator 1 is connected to the tester side via the logic circuit and logical judgement is made with the comparator. The probing line 3 is connected to the output side of the multivibrator 1 while probing and the output signal a is fed to the NAND gate 4 at the tester side. Further, the point K being the logical judgement- disable-time point of the multivibrator 1 to the input is detected, 0 of the output signal a to this point K is fed to the NOR gate 5, and wait signal is outputted from the gate 5 at the tester side while the tester wait period to stop the test operation at the logic judgement period and to execute accurate logical judgement.
