Data Bus Routing

ArmFpgaSDram

Well, seems it’s easier said then done. For the last week I’ve been trying to route my data bus (highlighted in the picture) to the FPGA (the left most IC). Considering I’m trying to do it on a two layer board I have no idea how I’ll do it. Feel free to leave a suggestion. Other possibilities include making a daughterboard with the ARM9 and memory. That would “Emulate” a 4 layer PCB and would allow me to reuse the “core” module.
