The trickiest parts are matching the pcb trace lengths for the DDR3 and
any clock lines used for time of flight (delay line) that are fed back
to the clock synthesizer.
The rest is just proper board stack ups, trace widths, vias types and
placement etc for some control over impedance, clock and power distribution.
The low cost and GPL pcb tools don't have much to help the designer. The
high end pcb tools give you micron accuracy.
So if there is anyway I can help keep things moving along...... don't
hesitate to ask.
