Zynq-7000 SoC - What do I do with an unused MIO_VREF pin?

Description

The MIO interface being used by the Zynq design does not require VREF. Can I use this as a general I/O like in SelectIO?  How should I connect it?

Solution

The VREF pin is dedicated and cannot be used as general I/O.  If unneeded, it should be left floating. This has been added to the latest version of User Guide 933, Zynq-7000 All Programmable SoC PCB Design and Pin Planning Guide.
