Newbie level 3
Hi all, I'm pretty new to PCB design and am getting slayed by the auto-router... not sure if this is an issue with ELECTRA but it seems like pretty reputable software... You can see in the image the bottom row of U11 isn't being routed to the right side of U1 on the first copper layer... any idea what would give? I've tried moving things all over for hours with no luck. It seems the first passes they are routed then when it does some sort of optimizations they get unconnected. I have the 2nd layer as a grounding plane and the third layer as a small 3.3V plane...4th layer for more trace/vias. not sure if this is an okay ordering; but doubt it's the issue (?).. anyways any help/suggestions are welcome. Thanks a lot!
