QCX incorporates a comprehensive set of default rule classifications for both schematic and layout. In Mozaix, classifications for design, sheet, symbol, packaging, part, net and library checks are available. In Pantheon are classifications for component clearances, fiducials, geometries, soldermask, testability requirements, and more that may be easily tailored to reflect the unique tolerances of each process line. The setup dialogs allow you to define rules interactively, or use topology scans of error-free boards to extract component clearance rules, net rules, and other pertinent information.
