You will need some kind of a level shifter to get the 3.3v signal from the Pi down to 1.8v and back if I understand correctly. I've seen everything from a single resistor to dedicated level shifter ICs in the Bitfury design thread.

Raspberry pi shield with just a few chips would be great. Avivmas, if you do that post the pictures.

I believe they both connect to 0.9V.
Sorry, that was totally wrong. IOVDD is 1.8V. IOREF is 0.9V.

Here's a link to a 49 page thread started by the chip designer. All of the questions you are asking have been answered in the linked thread. Also answered in this thread are most (if not all) the questions you're going to ask as you proceed with your project.

Is this a single chip setup per pi? Isn't it a bit costly to do that?
