Abstract
A semiconductor integrated circuit device includes a plurality of flip-flops configured to form a scan chain in a scan path test to operate as a shift register. The first flip-flop of the plurality of flip-flops latches a first input signal in synchronization with a clock signal, outputs a first output signal and fixes the first output signal based on the first selection control signal. A second flip-flop of the plurality of flip-flops latches a second input signal in synchronization with the clock signal, outputs a second output signal, and fixes the second output signal based on a second selection control signal. The semiconductor integrated circuit device further includes a control circuit configured to generate the first and second selection control signals such that a period during which the first flip-flop fixes the first output signal is different from a period during which the second flip-flop fixes the second output signal.
