Summary:The increasing need for validating heterogeneous Systems on Chip (SoC) before their costly fabrication gives rise to the development of numerous virtual prototyping tools, allowing not only the modeling of such systems, but also the simulation of the environment in which they will be embedded, including the crucial software. SoC designers indeed require flexible simulation frameworks that follow a component-based approach and that cover a wide field of physical/engineering disciplines... and no questions asked about the simulation intrinsics. Furthermore, for SMEs, laboratories, and enthusiastic makers with limited funding, the cost of these frameworks makes them unaffordable, especially when the target system hardware is supposed to be Open Source too. In this paper, we detail the principles of an Open Source SystemC Multi-Disciplinary Virtual Prototyping (SystemC MDVP) framework, which directly tackles with all these issues. We introduce the key concepts and methodology (relationships between Models of Computation and overall synchronization techniques) and insist on the importance of a "correct by construction" global model elaboration that allows to generate the hierarchy of solvers that make up the final simulator. We then show that a new Model of Computation, Electrical Network, has been added to SystemC MDVP to handle components with non-linear beahviors. The paper concludes with a quick presentation of the echOpen project which aims at designing a low-cost portable echography device modeled and simulated with the nresented nrincinles.
