摘要： A computer-readable, non-transitory medium stores therein a design support program that causes a computer executing tentative wiring processing between a first terminal group and a second terminal group in a tentative wiring area to execute a process. The process includes detecting unwired nets occurring in the tentative wiring area consequent to the tentative wiring processing; updating the tentative wiring area by expanding the tentative wiring area according to the number of unwired nets, if any unwired nets are detected at the detecting; controlling to execute the tentative wiring processing and the subsequent detecting with respect to the tentative wiring area updated at the updating; and determining the tentative wiring area to be a wiring area if no unwired nets are detected at the detecting.

摘要： A non-transitory computer-readable recording medium storing a design supporting program causes a computer to perform: acquiring non-complying line lengths of a plurality of wiring paths; drawing for each of the wiring paths a wiring pattern connecting a transmission origin and a transmission destination based on a line length and a wiring route of the wiring path; and controlling the drawing to draw a line for each of the wiring paths, the line being divided into a first line amounting to a non-complying line length acquired at the acquiring and a second line being a wiring pass less the non-complying line length.
