Abstract
Various implementations described herein are directed to an apparatus having a receiver module that receives a floorplan of an integrated circuit having power gates, an obstruction, and a control pin for providing a sleep signal. The apparatus can include an identifier module that identifies where the obstruction interrupts a sequence of the power gates, organizes the sequence of the power gates into a column, and divides the column into segments in which a first segment lies below the obstruction, a second segment lies above the obstruction, and a third segment is offset from the first segment and the second segment. The apparatus can include a stitcher module that performs a sleep signal stitching for the integrated circuit by distributing the sleep signal from the control pin to the power gates that include each power gate in each of the first segment, the second segment, and the third segment.
