Electromagnetic Modeling of Electronic Device by Electrical Circuit Parameters

This article proposes an electric model to determine the values of the electric fields of an electronic device. When applying the method, the integrated circuit device will be modeled on the resistance, inductance and capacitance values (R, L, C parameters) provided by the IBIS (Input/Output Buffer Information Specification), also considering the internal activity of the integrated circuit. The electric parameters of the printed circuit board tracks will be extracted by software based on the moments method and fast multipole method. Simulations of the electric model are performed in the time and frequency domain by the Fourier transform, and from the obtained harmonics, the values of the electric fields are calculated with software based on the finite elements method. Measurements were performed in order to validate the simulations.
