Abstract
A system and method for laying out power grid connections for standard cells are described. In various embodiments, a standard cell uses unidirectional tracks for each of the multiple power vertical metal 3 layer tracks and power horizontal metal 2 tracks. One or more of the multiple vertical metal 3 layer posts are routed with a minimum length based on a pitch of power horizontal metal 2 layer straps. One or more vertical metal 1 posts used for a power connection or a ground connection are routed from a top to a bottom of an active region permitting multiple locations to be used for connections to one of the multiple power horizontal metal 2 layer straps. Two or more power horizontal metal 2 layer straps are placed within a power metal 2 layer track without being connected to one another.
