Virtuoso XL Layout Editor User Guide

Preparing Your Design for Routing in the Virtuoso XL Layout Editor

Virtuoso XL places the via between the two layers. The next segment you draw appears on the new layer.

You can then switch back and forth between layers, choosing the new layer from the

Create Path form each time you change layers.

Note: There are no options forms for the Create – Rectangle command or the Create

– Conics commands.

The Create Polygon form appears.

4.Change the Snap Mode to the setting you want.

5.Click to place the first point.

6.Continue clicking points to draw the shape.
