PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit, and to provide a designing method for the circuit having high performance. SOLUTION: A semiconductor integrated circuit includes: a logic circuit (first circuit 1) for generating an enable signal, indicating whether a clock is valid/invalid from an input signal; a clock gating circuit (AND circuit 20) for inputting the enable signal and a clock signal and outputting a gated clock signal; a buffer circuit 21 for inputting a clock signal and outputting a buffered clock signal; a first low-through latch group (low-through latch 10) for inputting the gated clock signal; a high-through latch group (high-through latch 12) for inputting the gated clock signal; and a second low-through latch group (low-through latch 11) for inputting the buffered clock signal.
