Design method for semiconductor integrated circuit device

摘要

A design method for a semiconductor integrated circuit device enabling flexible selection of IPs while securing the functions of a system is provided. The design method of the present invention includes the steps of: (a) storing a plurality of IPs having the same function in a memory for each of a plurality of functions; (b) constructing a function group structure for satisfying a certain specification; and (c) selecting and retrieving one IP from the plurality of IPs having the same function from the memory for each function in the function group structure and substituting the IP for the function in the function group structure.
