The autorouter can route diagonal wires when it needs to during diagonal memory routing, through staggered pin arrays, and near existing diagonal wires.
4 l2 }5 U4 i& L0 A5 b: _* h, nIn 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.
- H) N7 c' N7 n2 d1 oThis option causes the majority of wires to have diagonals.

The autorouter never routes diagonal wires and routes only orthogonal wires.

Causes the autorouter to do the following:) g$ N) u/ y2 H7 Z' t
- All connections inside the soft fence are routed within the fence boundary.
- All connections outside the soft fence are routed outside the fence and cannot cross the fence.
- All connections that cross the soft fence ignore the fence. % u4 y* y! i" K) x
