PURPOSE:To reduce time and data volume required for test by inputting a test signal to RAS circuits of the same type to collectively test functions of the RAS circuits. CONSTITUTION:A same circuit deciding circuit 111 checks mounting states of RAS circuits of the same type based on the mounting data of a circuit board stored in a mounting data storage means 141. A test data converting means 113 converts data, which is stored in a test data storage means 131 and is required for the function test of RAS circuits, to signal to be inputted to RAS circuits to be tested. A data distributing means 115 inputs the test signal converted by the test data converting means 113 to a circuit testing means 117 in accordance with mounting states of RAS circuits obtained by the same circuit discriminating means 111. The circuit testing means 117 collectively tests RAS circuits and outputs results. |
