The receiver offset control (OFFSET_CNTRL) feature allows offset cancellation in receivers for certain I/O standards to overcome offset variations due to process.

The valid values for the OFFSET_CNTRL attribute are:

CNTRL_NONE (Default)


Note: OFFSET_CNTRL = MEM_CTRL is not a valid option.

The OFFSET_CNTRL attribute uses the following syntax in the XDC file:

set_property OFFSET_CNTRL value [get_ports port_name ]

To invoke the offset cancellation feature in an I/O bank, OFFSET_CNTRL must be set to FABRIC. The controls for offset cancellation are available using the IBUFE3, IBUFDSE3, IOBUFE3, or IOBUFDSE3 primitives.
