PURPOSE:To simplify the hardware constitution of a gate array tester by giving a shifting function to a buffer register and transmitting and receiving signals between a tester body and a performance board in units of a number of shift bits. CONSTITUTION:The output of each pin of an LSI10 to be measured of a gate array chip is stored in a corresponding bit position of a buffer register 31 in a performance board 30. Since this register 31 has the shifting function, information of every bit outputted successively from the buffer 31 is applied to a tester body 20 through control boards 321, 322..., a driver/receiver circuit 33, etc. of the board 30. Thus, the hardware constitution of the performance board of the gate array tester is simplified. |
