Design Verification Commands

Design Verification deals with geometries that are grouped into logical "layers". A DV layer is a collection of geometries that are used as input/output for DV commands. The geometry of a DV layer may be saved as results that can be later viewed in the Layout Editor. The contents of a DV layer may be imported from the Layout Editor or created by a DV command.

A DV layer contains the following types of graphical information:

• Error Clusters — Grouped segments that represent the results of a DV check. Usually a cluster contains two segments, but under certain conditions there may be more or less. These segments contain no polygon information. Segments may be a single point.

• Polygons — Closed geometric figures that may contain holes. These polygons may be grouped.

• Edges — Segments that contain some relationship information from previously belonging to a polygon. An edge, for instance, contains the directions "inside" and "outside" of the polygon and is able to determine if another edge was part of the same polygon. This information allows the edges to be used as input to other DV commands.

DV commands return DV layers with error clusters or polygons. Import commands, Object Creation commands and Connectivity Checking commands return DV layers containing polygons. There are DV (Geometry Checking) commands that return each type of DV layer.

DV layers containing polygons may be used as input to any command. DV layers containing polygons or edges support rule "conjunction", using the output of one check/operation as the input to another. DV layers containing error clusters may only be used as input with the SaveLayer command.

The following commands return DV layers containing polygons:
