Advances in Radio Science Proposal for scalable models in EMC simulation

Abstract. In this paper a method “Component Series Mod-eling ” (CoSeMod) is presented. This allows fast and easy implementation of scalable model generations for passive component series based on measurement data or specifica-tion provided by manufacturer. These can be used in circuit models for fast EMC analysis and optimization, especially in frequency ranges where conducted emission and suscep-tibility dominate. EMC tasks require high precision equiv-alent circuit models of components. Models generated with CoSeMod provide in many cases as high a quality as origi-nal (static) models do. One feature of scalability is that new netlisting is not needed after component changes. The pro-cess of model creation is based on similarities of the com-ponents of the same model series (packaging, manufactur-ing process, material etcetera). Required equations of the relationship between nominal and parasitic values are cal-culated by nonlinear regression. Model generation for un-known components of a known series is possible with inter-polation. Implementation is possible with relatively simple actions made in circuit simulator Saber. An EMC applica-tion example of the implemented model is also shown in this paper.
