Automated extraction of the passive distribution network of an integrated circuit for the assessment of conducted electromagnetic emission

This paper introduces an automated extraction flow for the passive distribution network (PDN) of a complex integrated circuit. This extraction makes it possible to predict the propagation of external and internal electromagnetic disturbances on power supply networks inside the circuit and, consequently, to have a better knowledge of the conducted emission and immunity of this circuit. This method can be implemented in an industrial design flow. Comparisons between simulations and measurements demonstrate the validity of this approach.
