PROBLEM TO BE SOLVED: To reflect a pin swap in package design in designing a circuit that uses an FPGA as a component. SOLUTION: An FPGA-information management unit 110 of a circuit-design CAD apparatus 100 retrieves FPGA information, such as pin-assignment information and attribute information, that is created by an FPGA-design CAD apparatus 10. A library creating unit 120 creates a symbol library by using the FPGA information. A pin-swap processing unit 150 retrieves pin swap information from a package-design CAD apparatus 20, and reflects the pin swap in the symbol library, the FPGA information, a circuit diagram, and a constrained condition.
