A semiconductor integrated circuit includes a plurality of shift registers to which test patterns are supplied, a pseudorandom number generator configured to generate, based on the test patterns supplied to the shift registers, pseudorandom numbers utilized as masking information corresponding to output responses of the shift registers, a masking information inverter configured to invert, on receiving a first control signal, the masking information corresponding to the output responses of the shift registers indicated by the first control signal, and an initial value storage configured to store initial values of the pseudorandom numbers. In the semiconductor integrated circuit, the pseudorandom numbers generated by the pseudorandom number generator are, on receiving a second control signal, initialized with the initial values of the pseudorandom numbers stored in the initial value storage. |
