PROBLEM TO BE SOLVED: To reduce design manhours by carrying out automatic design, and to improve quality of a design object, in design of a system, an LSI, a circuit or the like. SOLUTION: In the case of using a database wherein information related to a plurality of circuits different from one another such as circuits having different parameters for a circuit scale, memory capacity, the number of pins, an operation frequency and the like, the parameters of each circuit are automatically analyzed, and a semiconductor integrated circuit is automatically designed so as to match to a requested specification according to the analysis design. Regarding a processor circuit, improvement, integration and the like of the processor circuit are carried out by automatically analyzing microcodes. When a block function IP including an arithmetic circuit element is used, the structure of the IP is stratified and a registered database is used, and a connection part of each function in the IP is extracted to the outside to construct a new IP or system.
