Abstract:
Various embodiments provide a constraint-driven environment to interactively determine coloring of layout components when the layout components are being modified or created and to provide feedback with visual aids to users in nearly real-time. Layout components are thus appropriately assigned to respective mask designs upon their creation. Various embodiments check or verify various constraints during creation or modification of layout components, and the layout thus remains design rule clean as constructed. Some embodiments use data structure(s) including information associated with mask identifications of objects of a cluster to change some mask identifications without considering any of the constraints governing these mask identifications. Some embodiments further determine the mask identification for an object based at least in part on whether object splitting and stitching is permitted.
