Abstract:
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.
