Apparatus and method for logic description conversion.

摘要

A logic description conversion apparatus and a logic description conversion method are obtained according to which logic descriptions which include a long-term operation logic part which operates at an operation clock which is longer than a reference operation clock are converted into more advanced logic descriptions from which a logic circuit will be created accurately. Conversion-into-table means (1) receives a source code (SC1) which is formed by logic descriptions which include a multi-clock transfer path (long-term operation logic part), and generates a reference table (D1) which includes information about input control logic of an extracted register. Based on an indicator (D2) in which register name information of a receiving side of the multi-clock transfer path is registered and the reference table (D1), extraction and separation means (2) converts the source code (SC1) into a source code (SC2) which is formed by logic descriptions in which the long-term operation logic part and the input control logic are logically separated from each other. Since the long-term operation logic part and the input control logic are logically separated from each other, a logic circuit is accurately created by logic synthesis. <IMAGE>
