PROBLEM TO BE SOLVED: To facilitate countermeasures against noise in design.SOLUTION: A design support device 1 selects a feeding point 3 of a semiconductor integrated circuit that is arranged on a substrate model 2 in which a power supply layer and a grand layer are laminated; determines the arrangement positions of first protrusions 4 that protrude to the outside of the substrate model 2, on sides of the substrate model 2; determines the arrangement positions of second protrusions 5 that protrude to the outside of the substrate model 2, on positions of the sides which are away from the determined arrangement positions of the first protrusions 4 by a predetermined distance; and creates a substrate model 6 in which the first protrusions 4 and second protrusions 5 are arranged at the determined arrangement position. |
