Logic circuit, system for reducing a clock skew, and method for reducing a clock skew

1. A logic circuit comprising:

a first flip-flop configured to include a first input terminal introducing a clock signal, a first output terminal supplying the clock signal and a first internal wiring connecting the first input terminal and the first output terminal;

a wiring connected to each output terminal of a plurality of flip-flops adjacent each other and transmitting the clock signal which was amplified by a final stage buffer cell to a plurality of flip-flops; and

a second flip-flop configured to be adjacent to the first flip-flop and be supplied with the clock signal from the first output terminal via the wiring.

2. A system for reducing a clock skew comprising:

a final stage buffer cell specifying unit configured to specify a final stage buffer cell supplying a clock signal in a logic circuit that is subjected to a clock tree synthesis operation;

an F/F specifying unit configured to specify a plurality of flip-flops to which the clock signal is applied from the final stage buffer cell specified by the final stage buffer cell specifying unit; and

an F/F locating unit configured to locate the plurality of flip-flops around the final stage buffer cell.
