Rotated the layout 90 degrees to match the default orientation of
route layers, trimmed the ports and the bounding box to make ports flush with the bounding box edge. Brought the digital power and ground up to metal 4 for power routing. Modified the LEF to add use and class for each pin, and to extend the power route pins all the way up the left side.
