Manhattan Wiring (electronics)
"Manhattan wiring" is an electronics term. The wiring supposedly looks like Manhattan's grid system of streets.

http://en.wikipedia.org/wiki/Manhattan_wiring
Manhattan wiring (also known as right-angle wiring) is a technique for laying out circuits in computer engineering. Inputs to a circuit (specifically, the interconnects from the inputs) are aligned into a grid, and the circuit "taps" (connects to) them perpedicularly. This may be done either virtually or physically - that is, it may be shown this way only on the documentation and the actual circuit may look nothing like that; or it may be lain out that way on the physical chip. Typically, separate lanes are used for the inverted inputs and are tapped separately.

The name Manhattan wiring comes from looking at such a circuit diagram. It is reminiscent of how the roads in Manhattan, New York tend to criss-cross in a very regular grid.

Manhattan wiring is often used to represent a programmable logic array.

Still another possibility is to consider different physical wiring media, where the user can trade off manhattan wiring versus diagonal wiring.

As an example of this, again consider the impact of allowing 45 degree wiring in addition to Manhattan wiring. This has an obvious effect on all data
