A geometric approach for early power grid verification using current constraints

Abstract

The verification of power grids in modern integrated circuits must start, at design time, where circuit information is unknown but could be specified or inferred from design or architectural considerations. This work builds on previously proposed techniques to deal with circuit uncertainty in the framework of linear current constraints, but proposes a cost-controlled solution, by following a geometric approach, and transforming a problem that requires as many linear programs as there are power grid nodes, to another involving a user-limited number of solutions of one linear system.
