Hard real-time systems constitute a critical class of complex discrete event systems. Such systems include in their requirements many constraints such as safety, security and timeliness. Failure to ensure these constraints could have catastrophic effects in particular uses.These constraints augmented by those imposed by the execution environment make complex and time consuming the development process.
Case studies have shown that a development process based on rapid prototyping and simulation allows significant reductions in the risk, cost and time associated with building complex systems. The purpose of this paper is to present a prototyping and simulation approach based on the combination of object oriented paradigms, statecharts and VHDL. An example of how this approach is applied to a concrete application is presented.
Juan Pablo GRUER was born in Argentina in 1949. He obtained an Electronic Engineering degree from Uiversity of Tucuman (Argentine). He lives in France since 1980. He obtained an Engineering degree in Computer Science From the Ecole Nationale Superieure d'Informatique et Mathematiques Appliquees de Grenoble, France in 1982. In 1989, he obtained a Doctorate degree from the Universite de Haute Alsace in Mulhouse, France. From 1982 to 1987 he worked as Real-Time application ingeneer for the industry. Since 1990, he is assitant professor in Computer Science at the Institut Polytechnique de Sevenans in Belfort, France, where he teaches Real-Time Systems and Computer Networks. His research interests are the modelling and simulation of Discrete-Event systems and the design of real-time systems.
