Simulations are widely used to explore and justify systems architectures ; but system simulations currently suffer from limitations which make them difficult to use for complex multi-systems analysis. Therefore tools and processes must evolve to accompany these major changes in order to support the designers in their quest of optimized design.
This article deals with new processes and tools which will take part; in a close future; in the determination; the verification and validation of systems architectures. The results presented here were obtained during the CSDL project (Complex Systems Design Lab) partly funded by the French government.
