Closed-Form Expressions for Fast IR Drop Analysis

Several methods have been described for efficient power grid analysis, as presented in Chap. 21; (1) reduce the size of the linear system, (2) iteratively solve the linear system, and (3) apply advanced linear algebraic techniques to exploit the sparse nature of the power grid. Although these algorithms are faster than conventional linear solvers, significant computational time is required to iteratively apply these algorithms. An accurate closed-form expression would effectively solve this problem.
