Disclosed is an improved method and system for implementing and analyzing power switch configurations. Described is a novel approach to minimize the number of power switches required for a power domain and to automatically find the locations of those power switches subject to the constraints of saturation current and maximum IR-drop on the power switches. This approach uses a fast static power consumption analysis tool to compute the current and IR drop through the power switches. The approach can apply to both column and ring style power switch insertion methodologies.
