A semiconductor device includes a scan chain that scans out latch signals of a plurality of latches; a first switch that selects any one of an output signal of a combinational circuit and a signal of the scan chain; a first latch that is inserted into the scan chain and receives an output signal of the first switch; a second latch that receives an output signal of the combinational circuit; and a second switch that selects any one of a latch signal of the first latch and a latch signal of the second latch and supplies the selected one to a combinational circuit in a following stage. |
