Crosstalk noise peaks in output signals of nets of an integrated circuit layout design are estimated by first processing the design to estimate resistances and capacitances of the nets. The design is then processed to identify each aggressor net having at least one section that is proximate to a section of a victim net. A separate aggressor model is then generated for each proximate aggressor net section, the aggressor model including a current source and a capacitor. The design is then processed to identify each victim net that is proximate any aggressor net and a separate crosstalk model is generated for each identified victim net. The crosstalk model for each victim net includes the victim net's estimated resistances and capacitances and incorporates the aggressor model of each aggressor net section that is proximate to a section of the identified victim net. The crosstalk model for each identified victim net is then evaluated to determine a response to a signal applied as input to the victim net of a victim net output signal. The peak crosstalk noise in each identified victim net is estimated based on the response of the net's output signal.
