debumpify +Looks for U-shaped traces (with 90 degree corners) that can be shortened +or eliminated. + +
miter +Replaces 90 degree corners with a pair of 45 degree corners, to reduce +RF losses and trace length. + +
orthopull +Looks for chains of traces all going in one direction, with more +traces orthogonal on one side than on the other. Moves the chain in +that direction, causing a net reduction in trace length, possibly +eliminating traces and/or corners. + +

vianudge +Looks for vias where all traces leave in the same direction. Tries to +move via in that direction to eliminate one of the traces (and thus a +corner). + +
viatrim +Looks for traces that go from via to via, where moving that trace to a +different layer eliminates one or both vias. + +
