I don't see anything needing changes.
I think you may have trouble getting the board routed with that placement - you have a lot of signals to drop from the chips down to the connectors.
Yes, it's tight, but I think it can be done. I've just done up a quick proof of concept, and I think it will work. See the attached.I was originally having trouble with the capacitor, so I moved it. Then I ran into an impasse where the control bus signals couldn't be routed through the data lines because there were already top and bottom traces.So I spun the chips 180 degrees, and the connectors 180 degrees. The data lines fit, and don't interfere with the control bus. I now see there is room for the bypass cap in the original place, but I didn't bother updating the drawing. It will take some care, but I think it will fit.I've made all my comments in that other thread, so I have nothing further.
This is what I've done until now.
I didn't use autoroute, i prefered to do it manually.
The problem is that DRC tells me that i've too little space between wires, too little width of wires and too little drill size.
What is the min size of wires and vias for no DRC errors?
