Méthodologie et outil d’aide à la conception des systèmes multi-technologiques par VHDL

Abstract

This thesis deals with design methodologies of mixed-technology systems, as well as tools that assist developers in this design process. Although there are multitude design techniques, it is always difficult to manage the implementation of a complex system with high heterogeneity and which requires the use of different tools for design support. So, it becomes essential to put forward a methodology that simplifies and speeds up the process of development and verification. In this context, the work presented in this thesis proposes a methodology of design based on the modeling and an iterative simulation, this methodology is supported by material description languages VHDL and VHDL-AMS. This methodology integrates modeling techniques at different levels of abstraction and different stages of system design to quickly and efficiently validate the targeted system. Finally, as an extension to the proposed approach, we have designed a Hardware-in-the-loop simulation platform based on FPGA circuits, in order to enable affined verification and validation of mixed-technology systems and helps to quickly build a functional and efficient prototype. The methodology and the platform implemented in this work have been tested and validated through case studies derived from electrical power conversion systems.
