Abstract
Enhanced capability design-rule halos for use in Computer Aided Design (CAD) software programs are described. Such enhanced halos, created around a design feature at the design rule distance from that feature, have the following characteristics: beveled corners for closer placement of adjacent non-parallel and/or non-perpendicular design features, level-to-level design rule halos, following a bend or turn in a design feature, the design rule halo automatically adapts to bends or turns in the design feature and associated changes in the design feature following the bend, following a bend or turn in a design feature, the design feature and the design rule halo automatically snap back, as required, to avoid a design rule violation with respect to an adjacent design feature, and the design-rule halo is prevented from extending closer to an adjacent design feature than the design rule distance. These actions are performed real-time and interactively.
