EAGLE 9.4.1 How do I autoroute a range of signals?
See HELP AUTO for more information on what I'm about to describe. The easiest way to get those traces routed, would be to type the following into the command line:

AUTO U1_S* U2_S* U3_S*


Followed by the Enter key. The asterisk is a wildcard character that would pick up net names 1-32.

I encourage you to visit the Autodesk Forums where you can get help tailored to EAGLE.

Let me know if there's anything else I can do for you.
