Abstract

Les systmes lectroniques sont de plus en plus complexes et, dans le but de rapprocher le monde numrique et le monde physique, on observe l'mergence de systmes multidisciplinaires interagissant de plus en plus avec leur environnement proche. Leur conception ncessite la connaissance de multiples disciplines scientifiques tendant les dfinir comme systmes htrognes. Le dveloppement des systmes venir ncessite un environnement de conception et de simulation commun permettant de grer la multidisciplinarit de ces composants de nature varis interagissant fortement les uns avec les autres. Nous explorons la possibilit de dvelopper et dployer un environnement de prototypage virtuel unifi pour ces systmes. Pour surpasser les contraintes lies leur spcification et dimensionnement, cet environnement doit pouvoir simuler un systme htrogne dans son ensemble, o chaque composant est dcrit et rsolu en utilisant le MoC le plus appropri. Nous proposons un prototype de simulateur, SystemC MDVP, implment comme une extension de SystemC qui suit une approche correcte-par-construction, repose sur une reprsentation hirarchique htrogne et des interactions bases sur des smantiques maitre-esclave afin de modliser les systmes htrognes. Des algorithmes gnriques permettent l'laboration, la simulation et le monitoring de tels systmes. Une mthodologie pour incorporer de nouveaux MoCs est dfinie puis suivie afin d'ajouter le MoC SPH, qui permet la description de rseaux fluidique, SystemC MDVP. Nous avons modlis un systme RFID passif en utilisant plusieurs MoCs. Les rsultats sont compars avec des mesures acquises sur un vrai prototype physique. Current and future microelectronics systems are more and more complex. In a aim to bridge the gap between the cyber world and the physical world we observe the emergence of multi-disciplinary systems that interact more and more with their close surrounding environment. The conception of such systems requires the knowledge of multiple scientific disciplines which tends to define them as heterogeneous systems. Designers of the upcoming digital-centric systems are lacking a common design and simulation environment able to manage all the multi-disciplinary aspects of its components of various nature, which closely interact with each other. We explore the possibilities of developing and deploying a unified SystemC-based design environment for virtual prototyping of heterogeneous systems. To overcome the challenges related to their specification and dimensioning this environment must be able to simulate a heterogeneous system as a whole, for which each component is described and solved using the most appropriate MoC. We propose a simulator prototype called SystemC MDVP which is implemented as an extension of SystemC. It follows a correct-by-construction approach, relies on a hierarchical heterogeneity representation and interaction mechanisms with master-slave semantics in order to model heterogeneous systems. Generic algorithms allow for theAdvisors/Committee Members: Pcheux, Franois (thesis director).
