I am making a cartridge board, which pads that are lined up exactly (as if on top of each other) for the top (red) and bottom (blue) layers of the board. I love this auto router, it fails to do this routing, as it seems to be confused of not able to differentiate the top and bottom pads, thus keeping failing on routing attempt indefinitely. My board is 9cm x 9cm (plenty of space) contains only two PDIP chips, one 28 pins and one 14 pins.
Please advise how I can approach this problem. Thanks you!
