Study on component-based method of system-level modeling

In order to engineer system-level modeling process,improve the reusability of the model components,this paper proposed a general modeling method and component-based modeling approach.Uniformly,data Abstraction,signal primitives,asynchronous concurrent mechanism and other processes of modeling were summarized as modeling patterns.Furthermore,to facilitate the rapid prototyping and improve the reuse of model components,this paper created a typical hardware and software component model.Taking the wireless access system as an example,which was built according to component-based modeling method based on the simulation of the model,the influences of the number of stations on the valid throughput were analyzed in the WLAN(wireless local-area network).The practice shows that the component-based modeling method can speed up the modeling process and contribute to the achievement of the modeling process engineering.
