Why use average current for static IR?

o   Static IR drop analysis aims to determine the **average, steady-state voltage drop** across the power grid.

o   the baseline voltage level experienced by cells over a longer period, primarily influenced by leakage and the average rate of switching.

 

o   Average current calculated from average leakage and average switching power provides a measure of the continuous load on the power grid.

o   In some low-activity modes or technologies with high leakage, the average leakage current can be a significant contributor to the overall static power consumption and thus the static IR drop.
