It is provided a semiconductor integrated circuit device capable of easily designing a large scale circuit, particularly a circuit of a system LSI designed by combining circuits using plural intellectual properties and the like. The semiconductor integrated circuit includes a driving unit which is connected to a driven circuit via a transmission line and supplies a driving signal for driving the driven circuit to the driven circuit, a switch which is inserted into the transmission line between the driven circuit and the driving unit and which causes the driving signal, which is to be supplied to the driven circuit, to flow or to be cut off, and a transmission unit which is connected to the transmission line between the switch and the driving unit, and which transmits, to the driven circuit, a test signal supplied from outside the semiconductor integrated circuit device instead of the driving signal. |
