This is really impressive and I love how it came into existence out of necessity.
Could you share the application that you're using this backplane for? Is it a (very expensive) hobby project or a real world use case? You don't often see projects with a 12 layer PCB where the routing isn't critical in terms of reflection.
- wanderingjew 1y agoIt's for a 4096-node cluster arranged in a 12-bit hamming-distance 1 graph. If you know what I'm talking about please don't spoil it for the others. Yeah, it's a very expensive hobby project, but I can see some applications for similar pathological backplanes and BGA escape routing. Of course it doesn't do impedance control, length matching or differential pairs, but this could be useful on a _very small subset_ of _very complex boards_. Basically I accidently stumbled into one of the hardest routing problems I've ever seen, and decided to build an autorouter. And that might be useful for other people.
