Orthogonal circuit element routing
Abstract:
Various embodiments include computer-implemented methods, computer program products and systems for aligning a set of orthogonal circuit elements in an integrated circuit (IC) layout. In some embodiments, a computer-implemented method for aligning a set of orthogonal circuit elements in an IC layout includes: classifying each orthogonal circuit element in the set of orthogonal circuit elements as including a first space-designated edge and a second space-designated edge; and aligning each orthogonal circuit element on an edge placement grid according to the first space-designated edge and the second space-designated edge, the edge placement grid having a first set of space-designated grid lines separated by a first distance, and a second set of space-designated grid lines separated by a second distance, wherein the first set of space-designated grid lines is separated from the second set of space-designated grid lines by an offset distance.
