I have a board with three 32 input analog multiplexers, along with more components, connected to a 96 way DIN connector. How do I manually tell the autorouter to select only the muxers signals? I tried "AUTO U1_S[1..32]" for the first muxer but apparently eagle bugs out and select only up to U1_S3, ignoring it is actually 32 instead of 3.

I tried to select them from the design manager but it doesn't seem to care at all an routes the whole board.

It is a bug or a feature and I'm doing it wrong? I know I can manually click all 96 wires but... I would have to do it every single time and that's not cool.

All three muxers follow the same naming schema, as U1_S1..U1_S32, U2_S1..U1_S32..., etc

Ignore the fact that the autorouter is evil, that it creates weird traces and so.. but routing a 96way 3 row DIN connector is quite tricky for me and the autorouter already does the 100% of the board, but I'd like to try "guiding" it selectively.

I'm learning how to do it on the go, so please be kind. Also I'm aware that this is not a DIL atmega board with headers. If I need to write down all 96 nets and copy and paste from notepad...that's ok too but if there's a more human friendly obscure way the better.

Thanks

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.

  • \$\begingroup\$ In a similar topic.... - How do I select a subset of those nets? Is not implemented yet? I think the bus suffixing schema of [x..x] would be just fine for the autorouter. - Is there a chance I could mouse-drag select nets from the board layout for the autorouter for those times where you clustered a circuit and it has different net names. I know I could rename them and prefix them with a specific name but....I think that could come in handy too \$\endgroup\$ – Jose Rodriguez May 31 at 8:42
