Ultrascale PCI33_3 IO standard.

Hi,

 

It is known that Ultrascale does not support IO standard PCI33_3. If migrating from 7 series to Ultrascale, what should we do to IOs with PCI33_3 standards. Is there an equivalent for PCI33_3 in Ultrascale.

 

Thanks,

-Karthick

K,

 

There is most likely no possible way to meet the PCI33 standard in UltraScale.  It can probaly be made to work in selected cases, and may require level shifter/voltage translation devices as well.

 

I would be concerned with reliability as it is a reflective wave bus, and the voltages are going to be beyond our recommended values.  We validated PCI33 as a special case in the past, and held to our reliability estimates.  We cannot do that here.
