Abstract
The size of Today's digital systems is increasing very quickly. So design tools have to allow the maximum reusability and an adapted level of description depending on our goals during each part of design cycle. Moreover, systems require more and more heterogeneous competency domain. Then we have to be able to manage the integration of complex and heterogeneous software and hardware systems. In some previous articles, we presented an object-oriented method and the related tool, which were demonstrated to be useful in order to model and simulate hardware digital architectures and theirs software applications in order to obtain performance estimations.This paper firstly intends to show the easiness to integrate in our framework some capabilities to describe parts of system behavior with others formalisms. Indeed, due to description power of our generic object-oriented model and without any modification, we managed to take care of components the behavior of which is described using the synchronous reactive language Esterel. And secondly, we illustrate the use of our new extensions to model efficiently an automatic control system for sprinkler.
