Any solution to this? I have the exact same problem

@joshman101 nope and nobody answers

If the circuit is too complicated and it can't find a way to route all lines then it just stops, at least that's what i experience!

The only solution to autorouter problems for any PCB design tool is to not use it and route the traces yourself. Usually the circuits people make aren't so complicated that you really need the autorouter. Learn some more about electronics, look at other product PCB's, take some courses, and most importantly, route your own boards. That's the only way to learn. You'll make mistakes, learn from them. But the biggest mistake is pressing start on the autorouter and thinking what it spews out is great. It won't be easy, but you'll gain so much, have some experience from it. Unless you really know how and why you are using it, and have spent the time to set up your design rules and placed your components reasonably, the hand-routing isn't hard at all. You can really notice a badly autorouted PCB when it doesn't make sense why the power traces are so thin, signal traces are too close, go through weird spaces, the components are weirdly far apart from each other. If you really want to use the autorouter, have the design rules set up for the PCB company capabilities you are going to order them from. For example JLCPCB: [https://jlcpcb.com/capabilities/Capabilities](https://jlcpcb.com/capabilities/Capabilities) Read this thread about autorouting in EEVBlog: [https://www.eevblog.com/forum/beginners/why-should-i-route-traces-by-hand-when-i-have-my-autorouter/](https://www.eevblog.com/forum/beginners/why-should-i-route-traces-by-hand-when-i-have-my-autorouter/)

@deskpro256, Excellent advice. :) Some of the stuff I have put into (2.2) in (3) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) should give a bit of helpful background to the philosophy behind PCB design (although the section on PCB design itself needs more content!).

hi, i had a simmilar Problem, Autorouter (AR) wordked fine, but "suddenly" after minor manipulations it did not: * AR Conection closed (lokal) but EasyEDA (EEDA) did 't come back, status window got stucked with 0%, it had to be canceled * AR was not able to complete a high % was not finished * AR take very long or do not come back at all (not like the firts), AR connection is kept, it had to be canceled After playing around for some hours, it worked after cloding EEDA & AR, but this helps somtimes not at all or AR just works for 1 or 2 runns. Finnaly it found that it seems that when i **delete the PBC Boradoutline and create it new,** that this resolves at least my Porblem

@wilfried.fabian1, IIRC, if the Board Outline is not closed then I think the autorouter will fail.
