Identification of power sensitive scan cells

Abstract

Aspects of the disclosed techniques relate to techniques for identifying power sensitive scan cells. Signal probability values for signal lines in a circuit design are first computed, wherein the signal lines comprise signal lines associated with scan cells in the circuit design. Toggling probability values are then computed based on the signal probability values, wherein the toggling probability values comprise toggling rate values for the scan cells. Toggling rate reduction values are then computed based on the toggling probability values, wherein the toggling rate reduction values comprise toggling rate reduction values for the scan cells. Finally, scan cells having high toggling rate reduction values are identified.
