PROBLEM TO BE SOLVED: To reduce loads on layout design.SOLUTION: A design support device 10 calculates a crosstalk noise value in the case that no power supply cable runs in parallel with a signal line in each of a plurality of zones. The design support device 10 calculates a coefficient Fshield that becomes larger as the region of an electric power cable included in the region between two signal lines decreases in size, on the basis of a relative position relation between the two signal lines and the power supply cable in each of the plurality of zones. Also, the design support device 10 corrects the crosstalk noise value corresponding to the zone using the coefficient Fshield corresponding to the zone in each of the plurality of zones. Further, the design support device 10 calculates the total of the corrected crosstalk noise values corresponding to the plurality of zones respectively as a crosstalk noise value between the two signal lines. |
