Provided is a semiconductor integrated circuit which includes a logical operation circuit, a clock generator, a relay circuit, and a signal generating unit that are integrated. The clock generator generates multiphase clocks. The relay circuit distributes the generated multiphase clocks to the logical operation circuit. The signal generating unit detects phase states of the distributed multiphase clocks and, based on the detected phase states, generates an analog voltage signal having a voltage value indicative of a phase error in the multiphase clocks.
