Electrical Model of a Microcontroller for EMC Analysis

In this paper a new methodology to model the power supply network of complex integrated circuits by means of circuit and electromagnetic simulations of internal building blocks is proposed. The models obtained by adopting this methodology can be employed by silicon manufacturers to perform SPICE-like simulations in the early phases of a chip development with the aim to analyze and optimize their designs in terms of EMC performances. The comparison between measurement results on an 8-bit microcontroller with model simulations validates the proposed approach.
