2 State of the art

There are no state of the art methods available for the efficient simulation of all electromagnetic emissions from the kHz to the GHz range of complex devices, such as described in Chapter 1.
For accurate simulation of these devices, the ICs, the active and passive components, the structures on the PCB, external cabling and external electromagnetic environment (i.e. scattering objects), and even the software coding have to be properly considered in the model [6][7][8][9]. Currently three somewhat differing approaches for the development of suitable simulation methods for this purpose can be found in the literature. These three approaches, their current state, and their future potential to meet the objectives of the EMI simulation task are described in the following sections.
