Program descriptions ( 1 ) which define a plurality of devices by employing a program language capable of describing parallel operations are input, the input program descriptions are converted into an intermediate expression (S 2 ), parameters which satisfy a real-time restriction are generated for the intermediate expression (S 3 ), and circuit descriptions which are based on a hardware description language are synthesized on the basis of the generated parameters (S 4 ). The intermediate expression is a concurrent control flow flag, a temporal automaton having a concurrent parameter, or the like. Parametric model checking is performed for the parameter generation. The program descriptions define the devices by using a "run" method, and define the clock synchronizations of the devices by using barrier synchronizations. Thus, a bus system meeting the real-time restriction can be designed.
