Modélisation en langage VHDL-AMS des systèmes pluridisciplinaires

Abstract : This PhD work is focusing on heterogeneous system modeling issues with the involvements from the French research laboratory LAAS-CNRS and the company Mentor Graphics. The work is part of a well defined design process based on EIA-632 recommendations and on model driven engineering. The objective is to demonstrate how behavioral language such as VHDL-AMS can answer to the modeling and the simulation problems related to the physical design under EIA-632 recommendations. The thesis starts from the state of the art of system design modeling requirements, and follows by evaluation of different modeling languages. VHDL-AMS standard (IEEE 1076.1-1999) has been selected for being best physical solution available. In order to migrate from proprietary standards to VHDL-AMS, our work focuses on defining appropriate methodology. Our process flow is based on the model driven engineering where model transformation concept is being used. We use the transformation concept to converging to VHDL-AMS code. We also use the meta model concept to create the VHDL-AMS meta model which will be useful for checking the conformity and for defining transformation rules at the meta model level. Companies that are looking for solutions to migrating from proprietary models such as MAST to VHDLAMS provide real test cases to our transformation methodology. We also compare such approach to a preliminary methodology based on using modeling expertise in both source and target languages. This highlights the feasibility of such transformation with a possible semi-automation and with experts involved at particular steps. Several models have been created to validate VHDL-AMS as virtual prototyping modeling language. In particular, a model for heterogeneous firing system of a pyrotechnic charge dedicated to an onboard missile location has been developed from specifications. It is an important device for our perspective projects.
