The IBUF_LOW_PWR attribute allows an optional trade-off between performance and power. This attribute is set to TRUE by default, which implements the input buffer in the lower power rather than higher performance mode.
Note: For receivers that are expected
to operate at data rates ≥ 1600 Mb/s, this attribute should be set to FALSE.
The IBUF_LOW_PWR attribute uses the following
syntax in the XDC
file:
set_property IBUF_LOW_PWR TRUE|FALSE [get_ports port_name]
