Method of Automatically Installing Discrete Wires

This wiring algorithm permits multiple crossing of wires interconnecting a plurality of circuit chips on a planar surface of a module without causing the weaving of the wires.

A wiring level is considered as being composed of two layers. A wire is assigned to either the upper or lower layer of a level, and remains in that layer throughout its length. Wires in one layer are allowed to cross those in the other without restriction as long as the crossings are sufficiently far away from the terminations of each wire. Crossings within a layer are not permitted. In this way, if a wire goes over a wire in the same level (2 layers), it can go over other wires, but a wire cannot go over some and under others in that level. Wires at different levels may, of course, cross without restrictions.
