For an accurate analysis of DDR4, it is very important to incorporate the Power Delivery Network into the simulation and analyze the effect of noise due to switching of the parallel bus signal groups.
In this series of videos, we'll learn how to model, simulate, and analyze a Power-Aware Parallel Bus System. Part 1 of 5 will teach you how to create a power-aware parallel bus system topology and analyze return loss results.
