In a semiconductor integrated circuit, there is provided a method for correcting crosstalk, which exerts an influence via coupling capacitance between wiring by the signal transitions between adjacent wiring, comprising the step of creating a candidate for buffer division, the step of creating a candidate for cell movement, or the step of victim net logic synthesis. Thereby, the crosstalk is corrected through the buffer division, the cell movement, or an increase of elements in number by logic decomposition, logic inversion and a change of fan-outs in number.

Method for correcting crosstalk

There are contained the step of forming voltage waveform information by calculating a voltage waveform of each instance of a semiconductor integrated circuit at a power-supply terminal based on circuit information and analyzing the voltage waveform of each instance, the step of forming voltage abstraction information by abstracting the voltage waveform information, and the step of calculating a delay value of the instance based on the voltage abstraction information.
