Abstract
PURPOSE: To ensure an easy test for the logic circuit including the register file by writing the test data delivered from the combination circuit into the specified register of the register file and then comparing the shift-out output value with the correct value.
CONSTITUTION: Register file 2 consists of plural units of the shift register and stores the test data into the specified register for the test of the logic circuit. The test data given from file 2 is read out and then applied to combination circuit 3 along with the output of register 1. Then the test data delivered from circuit 3 is written into the specified register in file 2, and the output value shifted out of shift data output line 14 is compared with the correct value. Thus, an easy test can be secured for the logic circuit including the register file.
