Abstract

A semiconductor integrated circuit includes a module configured to operate based on a clock signal, a voltage controlling unit configured to change a power supply voltage supplied to the module, a clock generating unit configured to supply the clock signal to the module, and a test circuit configured to operate at the power supply voltage based on the clock signal to emulate a delay of a critical path provided in the module, thereby testing whether the module properly operates at the power supply voltage, wherein the clock generating unit supplies a different signal, in place of the clock signal, to the module while the voltage controlling unit is changing the power supply voltage.
