An area (40) (called "I/O area") for layout of a plurality of I/O cells (11,12,13) is provided in the peripheral portion of a chip (1) and signal wirings (30,31,32,33) for transfer a test signal to the I/O cells are provided in the layout direction of the I/O cells. At least one of empty cells (16,17) provided in the I/O area, at positions where the I/O cells are not provided, has a repeater circuit (25) which constitutes a transfer path for the test signal. The repeater circuit receives the test signal and outputs the test signal. This structure provides a suitable semiconductor integrated circuit device adaptable for ASIC or so, which can adjust the delay of a test signal to be transferred along the chip's peripheral portion by suppressing an increase in the delay and degradation in waveform depression. <IMAGE> |
