Connectivity Extraction in Layout XL
This topic explains how the Virtuoso® Layout Suite XL layout editor (Layout XL) processes connectivity information and presents several ways to prepare your design for routing.
The Layout XL connectivity extractor verifies that the connectivity of your physical implementation is legal and generates violation markers indicating open and short circuits, weak and must connect violations, and illegal overlaps in the design.
You can specify the types of markers that are created and limit the number of open violations displayed using the controls on the Connectivity of the Connectivity form. You can view and manage the violation markers in the Connectivity tab of the Annotation Browser Assistant assistant.
