Abstract:
1. A machine readable storage medium containing a design structure in a data format, the design structure when processed by executing instructions on a machine is used in a design process of an integrated circuit, the design structure of said integrated circuit comprising: a first wire of a first level of wiring tracks; a second wire of a second level of wiring tracks, said second level being adjacent said first level; a first via connecting said first and second wires at a first location of said second wire; a third wire of a third level of wiring tracks, said third level being adjacent said second level; a second via connecting said second and third wires at said first location, said second via being substantially axially aligned with said first via; a fourth wire located a first distance from said second wire in said second level; a third via connecting said third and fourth wires at a second location of said fourth wire; and a fourth via connecting said first and fourth wires at said second location, said fourth via being substantially axially aligned with said third via; wherein said second, third, and fourth vias, and said third and fourth wires form a redundant path between said first and second wires that is redundant to said first via, wherein said first via and said redundant path are the only paths between said first and second wires.
