I've run into some difficulties when planning for integrating the Prop2 into a PCB when it comes out. Mainly, that if you want the IOs to use 3.3V or really any level besides 1.8V, you have to run two power traces around the IC.
One route can fit between the ground plate and the pins with no hassle. But the second power trace requires you to find a way to cram in a bunch of vias in addition to all the IOs traces and smoothing capacitors needed around the outside of the Prop. Also, connecting up the vias on the bottom layer of the PCB basically blocks off all of the space under the Prop from being used for routing on 2 layer boards.
So I guess my question here is do all of the VDD pins need to be routed to source power or are they internally connected enough for one or two of them to be enough? If they are, that would solve many a problem.
