EAGLE V6 Autorouter Ignores Certain Airwires

Former Member
Former Member over 14 years ago

Hi,

 

Inside the orange circle in the bottom left corner of the attached picture, there are two airwires that have not been routed by the autorouter using the default settings. As you can see, completing the trace is extremely simple, yet the autorouter seems to have ignored them. Does anyone know why? In a previous version of the layout, all the components on the board were in completely different positions, and in that earlier version, the autorouter ignored these two same connections as well, as if it has a grudge against them. I can route the wires manually easily enough in this particular case. However, for more complicated designs in the future, I am worried that the autorouter may choose to bypass certain airwires for some unknown reason. I did not observe this behavior in V5.11. Might this issue be related to the new V6 redesign? Is there a way to prevent this? In the schematic, I have already removed these two components and added them back in, just to see if that might fix it, yet the results are the same. Thank you.

    SOLVED . . . kinda.

     

    I deleted the offending components from the schematic. Then I closed all libraries. Afterwards I reopened the library that the components belong to and added them back into the schematic. And just to be certain, I did a library Update All. Now the airwires are being routed normally again. This feels more like a workaround than an actual solution though . . . .

    Adrian,

     

    Can you elaborate more on the steps taken to eliminate the air wire

    issue (e.g. " Then I closed all the libraries" too ambiguous how do you

    exactly close the libraries)? Also, have you found this approach to

    solve the air wire and auto router issue consistently?
