DATA STRUCTURE OF DESIGN DATA OF SEMICONDUCTOR INTEGRATED CIRCUIT AND APPARATUS AND METHOD OF DESIGNING SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

The present invention is directed to easily change design of RTL circuit data according to design specifications such as power consumption and operation frequency. RTL circuit data of a semiconductor integrated circuit includes a first description expressing a specific module or specific circuit element and a second description with which at least a part of the first description is replaced, thereby adding a new function to a specific module or circuit element. When a computer performs logic synthesis on the RTL circuit data, either logic synthesis is performed on the first description as it is, or a part of the first description is replaced with the second description and the logic synthesis is performed on the resultant is determined on the basis of selection information.
