METHOD FOR WIRE WIDENING IN CIRCUIT ROUTING SYSTEM

摘要

A method for designing an integrated circuit (IC) includes, in part, dividing the wires disposed in the IC into a multitude of segments each having a length extending from a first end point to a second end point. Each segment is then widened without overlapping any adjacent object. As an example, an intermediate, or expanded, segment is formed that includes the first and the second end points and has a size to overlap with an adjacent object. The method includes identifying regions in the adjacent objects that overlap with the expanded segment. For each of the identified regions, an expanded region is formed, which has a shape and size to enclose the identified object with additional spacing around the perimeter. Next, the size of the expanded segment is reduced to form the wide segment such that the wide segment does not overlap any of the adjacent expanded objects.

1. A computer implemented method for designing an integrated circuit (IC), the computer implemented method comprising:
dividing, using the computer, a wire disposed in the IC into a plurality of segments, each of the plurality of segments having a length extending from a first end point to a second end point; for each of at least a subset of the plurality of segments, forming, using the computer, an associated wide segment that does not overlap any adjacent objects; and replacing, using the computer, each of the at least the subset of the plurality of segments with the associated wide segment to form a widened wire.
