ABSTRACT:
In a switch level simulation system of the present invention, bidirectional switch models are allocated more accurately at locations which need to be bidirectional in circuit connection information and uni-directional switch models corresponding to the flow direction of a signal are allocated at the other locations. The connection information extracting section extracts the connection state of each device in a circuit indicated by circuit information and produces connection information. The input/output type determining section determines whether or not a switching device in a circuit is bidirectional and the flow direction of a signal in a uni-directional switching device, according to connection information. The circuit connection information generating section generates circuit connection information to be used by a simulation executing section, using the result of determining of the input/output type determining section.
