XADC is actually already used in the SDRAM controller….because it's uber fast DDR3 it's used to measure temperature and dynamically adjust signal timing.
Recursively search for mig_7series_v1_8_tempmon.v under usrp3/top/X300/coregen

I've never used an XADC before, but the documentation says that on-chip voltage/temperature sensors should be available, provided the XADC Vcc/Vaux are connected.
