Ultrascale LVDS support for HR and HP bank

[tchin123]

I received an error for a ultrascale device stating:  IO bank 66 has incompatible IO.

Bank 66 is a HP and I have assigned lvds_25 to this bank.

According to UG571 (v1.10) on page 12 and 13 Notes 2: it state that it support both HP and HR.

Therefore I have a conflicting issue where an error occur eben though UG571 state that it is suppotrted, please clarify this?

Use LVDS standard for HP and LVDS_25 for HR banks.  Be sure your VCCO is compatible.

Strange but according to ug571, a HR bank can support voltage range from 1.2 to 3.3v and in addition it stated lvds signaling support. I have already build my board based on this because I need this to support lvds-18 in HR bank. Is there a discrepancy in the table and figure? Seem like I have to resin my board if this is true.

please confirm.
