The liveness information that is obtained from behavioral synthesis and that shows the periods during which variables described in a behavioral level description have valid values is used for processing at a logic synthesizing stage, placement and routing stage, debugging stage, writing stage of circuit information to a reconfigurable device, or the like, so as to use storage elements that are to be allocated to the variables described in the behavioral level description in common and to achieve optimization such as minimizing data paths and the like. Also in a debugger and in a writing device for writing circuit information, the aforementioned liveness information is used to execute a task of not displaying invalid variables, a task of reducing the amount of information to be saved to an external memory, etc.
