<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional behavioral synthesis device has a difficulty in producing a semiconductor device corresponding to state retention behavior. <P>SOLUTION: The behavioral synthesis device in the invention comprises a behavioral synthesis part 10 and a power specification description extraction part 20. The behavioral synthesis part 10 determines a data flow graph for implementing behavior by behavioral descriptions, and operators and registers which implement an operation defined by the data flow graph; and generates a data path graph including the operators and the registers, and a control circuit for controlling processing orders based on the data flow graph; and generates RTL (Register Transfer Level) descriptions including the data path graph and the control circuit. The power specification description extraction part 20 specifies a variable to be controlled required for state retention behavior by processing attribute information included in behavioral descriptions, specifies a retention register corresponding to the variable to be controlled based on information about the register of the data path graph, and generates power specification descriptions including the retention register. <P>COPYRIGHT: (C)2012,JPO&INPIT |
