The industries of transportation as the space industry are faced with a strong global economic competition which sets economic constraints on the cost of the functions. The use of COTS (Commercial Off-The-Shelf) components in embedded systems is more and more necessary to shorten the development cycles and reduce manufacturing costs. The application of electronic components comes overwhelmingly from public sectors whose requirement is to provide, in short development cycles, technological innovations including risk and cost mitigation. These development cycles must incorporate the specific constraints of embedded systems which are subject to strong normative requirements in terms of robustness and especially in terms of ElectroMagnetic Compatibility (EMC). In order to anticipate the risk of EMC non-compliance at electronic equipment level, the use of simulation tools and the development of EMC components models particularly at Integrated Circuits level has grown in recent years.
