The ICEM draft proposal deals with an extension of the IBIS [1] standard, aimed at predicting conducted-mode as well as radiated-mode emission [2]. This proposal provides a modeling methodology for the power supply network and the current activity of an integrated circuit. Thanks to these models, predicting conducted-mode emission levels on the chip as well as on the application board becomes possible by the means of SPICE-based analog simulations. This allows the chipmaker to better choose the chip package as well as the number of power supply pairs, and the integrator to fine tune the number of power supply networks and decoupling capacitors. The corresponding models may be elaborated either in the design phase or from measurements performed as soon as the silicon becomes available. This article briefly summarizes the ICEM model, then introduces the proposed methodology aimed at obtaining the current activity model from the measurements performed on the current consumed on the power supply pins of an IC.
