Trouble with Autoroute function in EAGLE

Other Hardware General Electronics
1

Hello there :slight_smile:

I am working on a project which involves the development of a pressure sensor matrix capable of pressure mapping the force applied on a patient by a medical instrument.
The active measuring area consists of a matrix of 28 interdigitated electrodes on a PCB.
I am trying to design this, but I am having some trouble with the autorouting.
When i press the function it stays in 0% and doesnt seem to even start the process.
I played around a little with the design rules, but I am pretty new to this whole world and I am sure my problem is somewhere there, I just cannot seem to find it :o
Unfortunately I cannot attach an EAGLE file here, but if anyone has any idea what it could be and has the time to help me out, please contact me and I will send you the file somewhere else, so you can see my design for yourself.

I hope I am making sense here, and I really hope one of you out there with more experience can help me out!

Thanks a lot for your time

Try and autoroute a very simple circuit, like just a couple of diodes and resistors, so you can see if you do not have an installation fault.

If that works but you still can't route then look to your component placing, it can't auto route if there is not enough room.

Your pic of the board doesn't look right. You should have a rats nest of thin lines connecting each component. How did you connect them up in the schematic? Using the wire tool or the net tool?

Anyhow, if you want to send me your eagle files, I'll take a look for you.

Put the files in a ZIP file.
I use "peazip" for that.

Is this the only eagle project where the auto routing is not working? All your other projects have working auto route feature, right?
