This work deals with the extraction of ICEM parameters and its validation on the power supply network of a 8-bit microcontroller. The objective of the ICEM model [1] (Integrated Circuit Electromagnetic Model) for Components is to propose electrical modeling for conducted and radiation emission prediction [2]. The ICEM model is based on two sub-models. The first one models the power network of the I.C. and the second one models the I.C. activity as a current generator. The ICEM model can be used by the I.C. supplier to check the performances of the package, the number of power pins, and the noise rejection on analogue parts, ... The electronic system suppliers will use the model to optimize the power network and the decoupling network of the PCB and finally the level of conducted and radiated emissions. In this paper, only the power network modeling of the 8-bit microcontroller core is discussed. Two methods can be used to model the power network of the I.C. The first one is based on the extraction of the parasitic elements during the design phase (silicon lay-out, package, bond wires, ...). The second one, discussed in this paper, is based on the measurement when a silicon or an equivalent design is available. These two methods are presented in the ICEM cookbook
