  • Patent number: 9582632
    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.

  • Patent number: 8219955
    Abstract: In order to make it possible to automatically execute a wiring process which satisfies not only a design condition but also design quality relating to an electric characteristic, according to the embodiment, an automatic wiring apparatus includes a design condition changing section for changing a design condition in accordance with priority information regarding the design condition where a wiring process which satisfies the design condition cannot be carried out by a first wiring processing section, a quality allowability decision section for deciding whether or not quality of a wiring region can be allowed where a wiring process which satisfies the design condition after the changing can be executed by a second wiring processing section and an outputting section for outputting a result of the wiring process of the wiring region by the second wiring processing section if it is decided that the quality of the wiring region can be allowed.

  • Patent number: 8065654
    Abstract: A computer aided design system is provided that includes a display, an input unit for inputting a circuit search-range narrowing condition, and a processing unit for, when a circuit topology of a circuit to be designed is changed, finding recommended circuits by searching a database, which stores part data and circuit data, based on the circuit search-range narrowing condition, and displaying a list of the recommended circuits on the display.

  • Publication number: 20070198173
    Abstract: A return route search device includes a starting point/destination point setting section which accepts the setting of a starting point on a circuit from which a return current starts accompanied by a signal transmission on the circuit, and a setting of a destination point on the circuit to which the current flows. The return route search device further includes an easiness setting section which accepts a setting of easiness of conduction of the return current through each of portions on the circuit, and a return route search section which searches for a route when the return current flows from the starting point to the destination point on the basis of the easiness of conduction on the circuit.
