Has anybody used these?
We have two FPGAs on a board, a Zynq and an Artix7. We want to use the internal ADCs to read chip temperatures. We have been advised to ground the temp sense diode pins DXP and DXN "if they are not being used".
Unless the XADC has a separate temp sense diode, seems to me that shorting the external diode pins might kill our ability to acquire temperature internally.
I don't see any big downside to not grounding those pins.
