ABSTRACT
Due to resistance in the PDN, a voltage dierence, commonly referred to as the IR drop, is observed between the supply origin and loads. For an instantaneous current i(t) owing through a wire segment of resistance R, a voltage of i*R is dropped across the segment in the direction of current ow. e voltage drop seen at any point in the network is the sum of voltage drops of segments of any path from a supply source to that point.
