Abstract:
This disclosure describes a multi-height routing cell and utilization of the multi-height routing in an integrated circuit to reduce routing congestion in a standard cell design floorplan. The multi-height routing cell includes a bypass connection, or “tunnel,” that routes a signal through a non-routing layer and under an impeding power rail. The multi-height routing cell includes bypass connectors on both sides of the bypass connection that provide connection points for which to connect standard cells on opposite sides of the impeding power rail. As such, the multi-height routing cell provides a route underneath the impeding power rail and, in turn, reducing routing congestion in the standard cell design floorplan.
