System for managing LSI design part data

A system for managing LSI design part data to be used in LSI design, the system comprising:

• part data storing means for storing each of function, logic, circuit, and layout type design, part data, each of which includes elements, said elements including a functional element which defines a function of a device derived from the part data, a characteristic element which defines characteristic values of said device and a structural element which defines a physical structure of said device;
• means for selecting data from the thusly, stored part data;
• element extracting means for effecting an extraction process for extracting, from any one or more of the thusly selected part data which is inclusive of function, logic, circuit, and layout design part data, a specific element included in the selected part data;
• part synthesizing means for effecting a synthesis process for synthesizing a part by combining elements extracted by said element extracting means to generate new part data or by combining at least one element extracted by the element extracting means and an element input to said system to generate new part data, said part synthesizing means storing the thusly generated new part data in said part data storing means;
• process data storing means for storing extraction process data when an extraction process is effected by said element extraction means and for storing synthesis process data when a synthesis is effected by said part synthesizing means, said extraction process data specifying the extraction process, selected part data from which the extraction is effected and an extracted element, is to be extracted and said synthesis process data specifying the synthesis process, elements to be synthesized and the thusly generated new part data;
• and
• input means for providing instruction information to said element extracting means and said part synthesizing means.
