Abstract
A method of routing and sizing of wires in the formation of wiring paths extending through a region. More particularly, the method relates to optimizing the routing and sizing of printed wire circuitry on a single surface, such as on semiconductor devices.
Claims12
A method of routing and sizing wiring paths through a surface region, comprising:
- (a) defining borders on said region and lands at intersections of said borders so as to form a space intermediate each of said lands;
- (b) providing a plurality of guide lines each of which simulates an approximate wiring path, each said guide line extending through at least one said space and selectively intersecting one or more of said borders and lands;
- (c) positioning a number of imaginary circles of equal diameters in the spaces between said lands on said borders, said circles being equal in number to the number of guide lines in each said respective space;
- (d) dimensioning said circles so as to fill said spaces on said borders intermediate said bands;
- and
- (e) stepping said circles manually of said region while concurrently adjusting the circle diameters to fill the available spaces therebetween so as to form simulated wiring paths.
