so they could have the same documentation e.g. https://m-labs.hk/artiq/manual/core_device.html#nist-qc2

Is this just a matter of reordering rtio channels added for nist clock/qc2, and adding missing channels, or am I missing something else?

It's almost possible - the only issue is that zc706 does not have user SMA GPIO port. Too bad it's right in the middle... some kind of placeholder will be necessary?

You can add the user SMA on ZC706, it's on the hardware, simply not in the gateware stack.

Well, the problem is that according to both the user guide, and zc706 board schematics (most notably page 44, SMA and Testpoints), there is just no SMA GPIO available. Maybe I'm missing something, but I can see just clock, MGT RX/TX, MGT REFCLK.

Sorry I was looking at the wrong schematics. What about PMOD_1_0?

Looks good, compiles nicely as well. I think that's it, see the incoming PR.
