Abstract
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 is accurately created. A source code which is formed by logic descriptions which includes a multi-clock transfer path (long-term operation logic part), is generated to a reference table which includes information about input control logic of an extracted register. Based on an indicator in which register name information of a receiving side of the multi-clock transfer path is registered and the reference table, the source code is converted into a source code 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.
