Abstract
A design support apparatus calculates a crosstalk noise value when a power line does not run parallel, for each of a plurality of sections. Moreover, the design support apparatus calculates a coefficient Fshield that becomes larger with decrease in the area of the power line included in an area between two signal lines based on a relative positional relationship between the two signal lines and the power line in a section, for each of the plurality of sections. Moreover, the design support apparatus corrects the crosstalk noise value corresponding to a section, using the coefficient Fshield corresponding to the section, for each of the plurality of sections. Moreover, the design support apparatus calculates a total of the corrected crosstalk noise values corresponding respectively to the plurality of sections as a crosstalk noise value between the two signal lines.
