Abstract
By reusing circuit information designed in the past, the amount of computation for combining circuit information for layout and wirings is significantly reduced. A memory part stores a plurality of pieces of circuit information for forming circuits in programmable logic circuits. Each of pieces of the circuit information has an identifier of its own circuit information, and in the case where part or all of the circuit information is formed with other circuit information, has the identifiers of the other circuit information as reference identifiers, as circuit data thereof. An acquisition part passes specification circuit information from an application program to an editing part, obtains circuit information of a specified circuit, sent from the editing part, and forms the specified circuit in the programmable logic circuits according to the circuit information. The editing part generates circuit information of a circuit specified by specification information from the acquisition part from circuit information of the specified circuit and other circuit information indicated by reference identifiers, obtained from the memory part.
