This paper discusses the multi-domain modeling and simulation issues of the design and analysis of heterogeneous integrated systems. Modeling and simulation method- ology and tools are also discussed.

The complex silicon systems formed by the several specialized devices like SOC, RF devices, power devices, MEMS wafers are fabricated in dedicated technologies. If the designer attempts to integrate them into the one big multifunctional system, he meets the new, yet unexplored fields for the multidisciplinary, mutually dependent thermal, electrical, EM and mechanical parameters modeling. This article attempts to clarify, and presents how to simplify this problem.
