Introduction to the Virtuoso XL Layout Editor

The Virtuoso® XL layout editor (Virtuoso XL) is a connectivity-based editing tool that automates each stage of the design task, from component generation through automatic/ interactive routing. When used as part of an automated custom physical design methodology, Virtuoso XL lets you generate custom layouts from schematics or netlists and edit layouts that have defined connectivity.

Virtuoso XL continuously monitors connections of components in the layout and compares them with connections in the schematic. You can use Virtuoso XL to view incomplete nets, shorts, invalid connections, and overlaps to help you wire your design. It lets you both speed up and customize the layout process.
