Abstract: A wiring topology display method, includes: obtaining layout information indicating positions of components and wiring coupling the components; dividing first wiring into first pieces of partial wiring, and generating partial wiring information indicating the first pieces of partial wiring; identifying a first length of the partial wiring and a first angle of the partial wiring for a vector; identifying combinations of second pieces of partial wiring based on the first length and the first angle, the second pieces of partial wiring having second lengths which are a certain length or more, second angles which are different by a certain angle, and a distance which is a certain distance or less; identifying a group having the combinations including pieces of identical partial wiring; and symbolizing third pieces of partial wiring at both ends of the group and fourth pieces of partial wiring between the third pieces of partial wiring.

Abstract: A computer-readable-recording-medium stored a program for causing a computer to execute: judging, for each of elements of a plurality of scattering parameters, whether a difference between a first-area in a plane containing an axis representing frequency and an axis representing the element, and a second-area in the plane is within a permissible range, the first-area being surrounded by a first-element-value series of the element that is defined in advance for a plurality of first-frequencies, the second-area being surrounded by a second-element-value series that is obtained by performing interpolation calculation from the first-element-value series for a plurality of second frequencies which are different from the plurality of first-frequencies and which are provided at regular intervals; and determining, by performing the judging for one interval or a plurality of intervals, an interval so that the difference falls within the permissible range for all of the elements of the plurality of scattering parameter
