Abstract
A semiconductor integrated circuit comprises a combinational circuit section having a combinational circuit, a scan path circuit for inputting and outputting a value from and to the combinational circuit section in accordance with a scan enable signal and in synchronization with a clock signal, and a clock control section for generating and outputting a predetermined number of pulses as the clock signal after a predetermined period has passed since a time when an output command signal was received. The clock control section has an oscillator circuit for generating and outputting the pulse, and is configured to output a last pulse of the predetermined number of pulses in a manner which holds a logical value immediately after an active edge for the scan path circuit.
