RC (Design Rule Constraints) are the fundamental principles in constraining VLSI (Very Large Scale Integration) circuit designs to standardized physical and electrical manufacturability criterion.
Today's component miniaturization and density technologies require continual reassessment of best practice applications to keep design geometries aligned with realistic manufacturing capabilities.
Two-dimensional DRC layout patterns may prove to be mathematically and layout rules compliant.
But, when they are applied at the extremes of the manufacturing process tolerances, lithographic printability issues still arise.
DRC+ is a new methodology that can be implemented in identifying the issues around complex process methods....
