Abstract :
As power grid safety becomes increasingly important in modern integrated circuits, so does the need to start power grid verification early in the design cycle and incorporate circuit uncertainty of the early stages into useful power grid information. This work adopts the framework of capturing circuit uncertainty via constraints on circuit currents, and follows a geometric approach to transform a problem whose solution requires as many linear programs as there are power grid nodes, to another involving a user-limited number of solutions of one linear system.
