Websystem‘s IR drop may be budgeted into three portions. On chip IR drop, package and board. On-chip IR drop has been extensively studied because the resistive loss is severe due to the fine feature-size (a few microns and below) of the on-die power grid. On the other hand, package and board-level IR drop
