The design of electronic systems becomes more and more difficult mainly because of 2 points: - Increase in complexity and heterogeneity, - Engineers have more and more difficulties to meet the requirements of new integration possibilities. This explains the need of new design methodologies. The main goal of this work is to develop a new design methodology based on a global approach and modularity, whereby the behaviors and the communications are divided into different specifications. Each module is refined and simulated by specific and adapted tools. A coordination language specifies the global coordination and the simulation uses the cosimulation approach. The communication synthesis environment is used to refine communications to match the needed abstraction. This methodology can reduce drastically the "time to market" of a new product by the global approach and the early simulations. This methodology has been validated by a successful experiment on a VDSL modem carried out in collaboration with CNET (France-Telecom), ST-microelectronics, AREXSYS and TIMA on a VDSL modem experience.
