CROSSTALK ERROR CONTROL APPARATUS, METHOD, AND PROGRAM

A crosstalk error controller includes a crosstalk analyzer for detecting a crosstalk error net in which a crosstalk error has occurred, a noise source detector for detecting noise source nets being noise sources to the crosstalk error net, and a reducing unit for lowering a signal level of a noise source net to thereby suppress the crosstalk error in the crosstalk error net. It is therefore possible for a crosstalk error controller to control a crosstalk error even if the wiring density is high.
