Abstract :
The inverse layout tree concept is used to perform fully hierarchical DRC without any constraints on the use of overlapping or incomplete cells that are completed at higher levels of hierarchy. Hierarchy is preserved and design rule violations are displayed in the cell where they should be corrected. The DRC is corner-based and processes 200-800 corners/second on a VAX 11/750.
