Routing Tools Add Routing Use the Add Routing tool to insert new wires into a design. The simplest way to use this tool is to select a starting point and then click on a destination point.
SURF then chooses a short path that connects the two points without crossing any existing wires.
If the new wire has to squeeze between existing wires, the spoke expansion will try to spread them apart to satisfy minimum spacing rules. It is also possible to guide the path search by picking one or more intermediate hint points along the way before choosing the destination point. As each hint point is chosen, SURF completes the routing up to that point. When the path is finally completed, SURF cleans up any intermediate hint points by replacing the segmented path by a single rubber-band. This tool is that it will not permit routing cycles.
