National Instruments Ultiboard Working with Nets

Chapter 5 Working with Traces and Copper

5. Click Start Fanout. The Fanout Options dialog box disappears and

the fanout vias are placed on the design, as circled in the figure below.

Working with Nets

This section contains the following subjects:

•Using the Nets Tab

•Using the Netlist Editor

•Highlighting a Net

•Shielding Nets

•Net Bridges

•Copying a Copper Route

Using the Nets Tab

The Nets tab buttons in the Spreadsheet View allow you to preview a net

in relation to the board, find a net, highlight a selected net, lock and unlock

a selected net, set the width and clearance of a selected net, and remove the

copper of a selected net.

Complete the following steps to preview a net:

1. Click the Show preview button to toggle the Preview function on if it

is not already.

2. Click the net in the list. A pi cture of the path the net makes on the board

displays in the preview area.
