An object-oriented environment for fast simulation using compiler techniques

In this paper, an efficient simulation environment that utilizes compiler techniques to speed up simulation is presented. The method is based on the utilization of flexible, process-oriented modeling and event-oriented simulation, which provides minimum run-time system overhead. A compiler is implemented to transform a process-oriented model to an event-oriented model to completely eliminate the context-switches that are normally inherent in process-oriented simulation tools. Three different systems are simulated using the proposed method and are compared with DEPEND, a process-oriented dependability simulation tool. Results show that the simulation time is reduced significantly. The techniques proposed are general and can apply to process-oriented simulation models to speed up the simulation
