ABSTRACT:
In a multi-wide class design layout, design rule checks for enclosure of multi wide class objects prevent false errors or false passes by performing such checks against the non-virtual boundaries of a wide class object, and not against the virtual boundaries. An exemplary embodiment provides a method for identifying as a violation, for each wide class wiobject, any geometry on another layer which is located at least partially inside the wiobject and has any portion thereof located within a distance encliof any non-virtual boundary of the wiobject. The exemplary method is preferably performed using effective wide class objects.
