Abstract

PURPOSE: To secure easy formation of the test data in case the test is carried out by giving the test data to the tested logic circuit, by increasing the point where the actual action is compared with the expected value.
CONSTITUTION: Both the control signal and the writing signal for the test action are supplied to terminal 105 and 104, and the signal counting the address is applied to terminal 103. Thus, the test input data or expected value 101 and 102 are written into memory element 4. In the case of the actual test, the reading signal is supplied to 104 and the control signal for the test action is supplied to 105 respectively, and the signal to count the address is supplied to 103. As a result, the test input data of the expected value is read out from element 4 to be supplied to control circuit 5. Circuit 5 applies the test input data to logic A and the expected value to comparator 6 respectively. Circuit 6 compares the expected value with the logic value of the actual action with every point. And when no coincidence is obtained, the disagreement signal is delivered to pin 203
