摘要
The number of steps for preparing a layout diagram of a circuit including a coupler, which is formed by arranging a main line and a stub line in parallel with each other, is reduced. A circuit diagram editor 1902 arranges a coupler symbol 100 stored in a component symbol storage section 1904 when the coupler is arranged in preparing a circuit diagram. A layout section 1935 of a layout diagram editor 1922 layouts two wirings constituting the coupler by use of circuit diagram information and coupler information in which a coupler length and a coupler interval are defined. An object extraction section 1937 of a wiring check section 1936 extracts components and wirings from the layout diagram, and passes these to a wiring checker 1938. At this time, the coupler is passed to the wiring checker as one component that cannot be decomposed no more. Therefore, an interval between two wirings constituting the coupler is not checked.
