Abstract:

An apparatus and method for improved efficiency of operation of a circuit simulator. The simulation engine processor sends signals via flag registers to the component model processors to indicate which type of response is required from each component model. The component model processors send back only the requested response, thus minimizing processing time by avoiding generating response types that are not needed. Flexibility is enhanced by centralizing tasks in the simulation engine rather than in the component models, in order to facilitate experimentation and variation in circuit configurations without extensive modifications of component model design.
