Abstract
Systems and methods are described for sharing signals across a common metal trace on a single metal layer of an integrated circuit. The signals are time division multiplexed across the common metal trace such that a single metal layer of an integrated circuit is used to multiplex signals to and from a poly-silicon layer, reducing utilization of upper metal layers of the integrated circuit.
