DESIGN METHOD AND PROGRAM FOR SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To suppress power consumption within a range satisfying timing constraints.SOLUTION: A design device determines wiring lines L1-1 to L1-n for transmission of signals and wiring lines L2-1 to L2-n not used for transmission of the signals, out of a plurality of wiring lines L1-1 to L1-n and L2-1 to L2-n of a semiconductor integrated circuit 1. The design device determines to use the wiring lines L2-1 to L2-n as charge storage wiring lines for reusing the charges of the wiring lines L1-1 to L1-n in the largest number of wiring lines L1-1 to L1-n within a range satisfying timing constraints on the basis of the operation rates of the signals, which are transmitted to the wiring lines L1-1 to L1-n, and delay times of the wiring lines L1-1 to L1-n.
