Figure 1. Single-Ended Input Buffer Primitives

Table 1. IBUFE3 and IBUF Attributes
Attribute	Values	Description
IOSTANDARD	See Table 1	Assigns an I/O standard to the element.
USE_IBUFDISABLE	TRUE, FALSE	Enables IBUFDISABLE port (IBUFE3 only)

Table 2. IBUFE3 and IBUF Ports
Port	I/O	Description
O	Output	Buffer output representing the input path to the device.
I	Input	Input port connection. Connects directly to top-level port in the design.
IBUFDISABLE	Input	Disables the input buffer and forces the O output to the internal logic to a logic Low when asserted High (IBUFE3 only).
OSC[3:0]	Input	This is not a supported port and must be left unconnected.
OSC_EN[1:0]	Input	This is not a supported port and must be left unconnected.
VREF	Input	This is not a supported port and must be left unconnected.
