A circuit-design supporting apparatus that supports designing a circuit in which an integrated circuit is used as a component, the circuit-design supporting apparatus comprising:nan integrated circuit-information receiving unit that receives integrated circuit information, which is design information created by using an integrated circuit-designing CAD with respect to the integrated circuit; anda library creating unit that creates a symbol library of the integrated circuit to be used in a circuit design by using the integrated circuit information, the symbol library being a library defining a symbol of the integrated circuit, the library creating unit determining whether an existing symbol of the integrated circuit is arranged in a circuit diagram, and creating, if it is determined that the existing symbol is arranged in the circuit diagram, the symbol library based on information on an existing symbol library of the existing symbol, changes from the existing symbol to a symbol, whose symbol library is created, being fewest.

A circuit-design supporting apparatus that supports designing a circuit in which an integrated circuit is used as a component, the circuit-design supporting apparatus comprising:nan integrated circuit-information receiving unit that receives integrated circuit information, which is design information, including a pin attribute created by using an integrated circuit-designing CAD with respect to an integrated circuit used in a circuit;a determining unit that determines whether a component used in the circuit is the integrated circuit, the integrated circuit information of the integrated circuit being received by the integrated circuit-information receiving unit;an obtaining unit that obtains a pin attribute of the component from the integrated circuit information if the determining unit determines that the component is the integrated circuit, and obtains a pin attribute of the component from a component library if the determining unit determines that the component is not the integrated circuit; anda DRC unit that performs a design rule check on the circuit by using the pin attribute obtained by the obtaining unit.

A circuit-design supporting apparatus that supports designing a circuit of a printed circuit board in which an integrated circuit is used as a component, the circuit-design supporting apparatus comprising:na pin-swap-information receiving unit that receives pin swap information with respect to the integrated circuit from a package-designing CAD apparatus that performs a pin swap in package design of the printed circuit board and produces the pin swap information that is information on the pin swap;a pin-swap processing unit that updates a diagram of the circuit and reflects the pin swap into a constrained condition on circuit design by using the pin swap information;an integrated circuit-information receiving unit that receives integrated circuit information, which is design information created by using an integrated circuit-designingCAD with respect to the integrated circuit; anda library creating unit that creates a symbol library of the integrated circuit to be used in a circuit design by using the integrated circuit information, whereinthe pin-swap processing unit updates the symbol library created by the library creating unit with the pin swap information, and reflects the pin swap in the circuit diagram by updating a symbol in the circuit diagram with updated symbol library.
