Abstract:
1. A non-transitory computer-readable storage medium storing a program which causes a computer to perform a procedure comprising: locating data of a first component in a reference circuit which is imported into another circuit, as well as data of a second component in a product circuit which is designed by using the reference circuit; obtaining data of a first portion of the reference circuit by tracing wiring lines from component to component in the reference circuit, with the first component as a start point; obtaining data of a second portion of the product circuit by tracing wiring lines from component to component in the product circuit, with the second component as a start point; and outputting data indicating differences between the first portion and second portion, based on the obtained data of the first portion and the obtained data of the second portion, wherein the outputting includes: comparing first attribute values, included in a component table and a net table, of components and wiring lines included in the data of the first portion with second attribute values, included in the component table and the net table, of components and wiring lines included in the data of the second portion; and producing data indicating differences in the components and wiring lines between the first portion and second portion.
