The autorouter can route diagonal wires when it needs to during diagonal memory routing, through staggered pin arrays, and near existing diagonal wires.
/ W# K7 ~4 j' Q; aIn general, this option does not produce much diagonal routing.

The autorouter routes every wire with long diagonals, depending on the amount of available routing space. 8 v; f ]0 J. d! w6 z
This option causes the majority of wires to have diagonals.

- All connections inside the soft fence are routed within the fence boundary.
