Introduction
Single-ended signals used as simple inputs must use an input buffer (IBUF).
I/O attributes that do not impact the logic function of the component, such as IOSTANDARD and IBUF_LOW_PWR, should be supplied to the top-level port via an appropriate property. For details on applying such properties to the associated port, see the Vivado Design Suite Properties Reference Guide (UG912).
