PROBLEM TO BE SOLVED: To significantly reduce the time required for circuit design. SOLUTION: Circuit information is generated, which is composed including input/output relations between operation circuits from the output side to the input side of the overall electronic circuit, and information on the processing time by operation circuits. The generated circuit information is traced from the output side to the input side, and the delay time generated on the path connecting the operation circuits is calculated. A circuit of the four basic operations of arithmetic in which a plurality of circuits of four basic operations of different kinds are arranged on the output side are retrieved, and a delay circuit for synchronization to the maximum delay time is created between the retrieved operation circuit and each of the operation circuits other than the operation circuits on the path where the maximum delay time occurs among the operation circuits arranged on the output side of the retrieved circuit of four operations.
