Summary:In this paper, distributed power port method for the loop-inductance based simulation is proposed to take into account local impedance variations of the complex power plane in high-speed printed circuit boards and packages. Lumped power port method is not appropriate to model distributed power supply noise across multiple bytes whereas distributed power port can be used for byte-level granularity noise analysis as well as capturing transfer-impedance effect. In time-domain analysis, a new method to capture ground current is developed to compensate the drawback of the loop-inductance based simulation tools. Measured result correlates well with the simulation using ground current capturing method.
