Board Outline and Local EasyEDA Auto Router Issue
679 2
Kajetan321 3 years ago
Using: EasyEDA V.6.4.19.4 on Windows 10 EasyEDA local Auto Router This project illustrates how having an irregular board outline causes the auto router to not complete the routing. See PCB file "Auto Router success" to see that when the board outline is a simple shape, the auto router completes. See PCB file " Auto Router failed" here the board outline is irregular and the auto router freezes at 83%. Why does it seem that the complex shape causes the auto router to freeze?

@UserSupport, I can confirm this with local and cloud autorouters. The irregular outline routes up to 83% much more slowly than the simple outline and also routes very differently. One thing I can see is that the simple rectangular outline is a single polygon whereas the irregular outline is constructed from 3 lines. However, even after checking that the start and end points of the lines are exactly overlapping, the auto router still fails. * A suggestion for a workaround for this particular case: Autoroute the board with the simple outline then delete that and put the irregular outline round it.

EasyEDA auto router using open source FreeRouting project that seems Freerouting's bug we will update Freerouting to the latest version soon, maybe will solve this issue. Thanks @andyfierman
