Power distribution network design for high-speed automotive graphical processing module

For safety reasons, design specifications of automotive electronics, as compared to consumer electronics, are more stringent and complex. With increasing demand for high-end graphical displays in commercial vehicles, good power distribution network (PDN) design is critical to ensure the reliable operation of the circuits. This paper describes a systematic PDN design method of a high-speed printed circuit board (PCB). The PDN design and analysis of an actual modular system is presented.
