Predictive method for efficient transmission lines and multilayered Power/Ground planes co-modeling using Multi-Conductor Transmission Lines

As the layout density increases in highly integrated multilayer packages, the noise that exists in the Power Distribution Network (PDN) is increasingly coupled to the signal traces. Thus, precise modeling to describe this coupling phenomenon becomes necessary. This paper presents a fast and an efficient method to a predictive co-modeling of signal traces and multilayered Power/Ground planes. The method is based on Multi-Conductor Transmission Lines. A particular case of signal´s return path discontinuity is studied and corresponds to a microstrip-to-microstrip via transition.
