2016.2 Zynq UltraScale+ MPSoC: eMMC over EMIO requires an inverter for enable signals

Description

I am routing the eMMC port to EMIO in a Zynq UltraScale+ MPSoC block diagram design.

When I make it external and run automation, Vivado places an IOBUF, but the interface does not work correctly because the expected polarity for the enable signal is backwards.

Solution

An inverter is needed for the enable signals.


 

This will be fixed in a future release to include the inverter automatically when running automation.
