Routing Options: Bus Autorouting Tab
To autoroute buses, the topology for the nets, as set in the Net edit dialog
box, or the Spreadsheet View, must be set to either Daisy chain

and the nets must be part of a Bus Group as set in the Edit Groups dialog
box. You can also add new Bus Groups from the Bus Autorouting tab in
the Routing Options dialog box.
Complete the following steps to set Ultiboard bus routing options:
1.
Select the Bus autorouting
tab in the Routing Options dialog box.

Assigned Nets, click Edit. The Bus Groups tab of the Edit Groups
dialog box appears where you can Add or Delete bus groups. You can

selecting or de-selecting the group’s checkbox in the Assign Nets list.
