I want to used ultrascale to P&R, but report error message.
set_property PACKAGE_PIN AE46 [get_ports XDDR4B_CK]
set_property IOSTANDARD HSTL_II [get_ports XDDR4B_CK]
ERROR: [Place 30-855] The design has the following IO terminals locked to IO banks which do not support their respective drive strengths:
IO terminal XDDR4B_CK has drive strength 0 but it is locked to bank 44 which does not suppot this drive strength

On the HP banks you cannot set the drive strength. Are you using a HP bank? If you are are you setting the drive strength if not in the XDC file then maybe with the generic map of the OBUF instantiation?
