Esterel and Java in an Object-oriented Modelling and Simulation framework for Heterogeneous Software and Hardware systems. The SEP approach.

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 their 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 o
