Table 1-4: BUFGCTRL Attributes
BUFG
BUFG is simply a clock buffer with one clock input and one clock output. This primitive is
based on BUFGCTRL with some pins connected to logic High or Low.
the relationship of BUFG and BUFGCTRL. A LOC constraint is available for BUFG.
X-Ref Target - Figure 1-3
The output follows the input as shown in the timing diagram in
X-Ref Target - Figure 1-4
Notes:
1. Both PRESELECT attributes cannot be TRUE at the same time.
2. The LOC constraint is available.

summarizes the attributes for the BUFGCTRL primitive.
BUFG(O)
I
BUFG(I)
Initializes the BUFGCTRL output to the specified
value after configuration. Sets the positive or
negative edge behavior. Sets the output level when
changing clock selection.
If TRUE, BUFGCTRL output uses the I0 input after
configuration
If TRUE, BUFGCTRL output uses the I1 input after
configuration
