The primitives shown in the following table are different configurations of the clock BUFGCTRL buffers. The Vivado tools manage the configuration of all these primitives. Refer to the Vivado Design Suite User Guide: Using Constraints (UG903) for information on manually placing the BUFGCTRL locations with LOC constraint.

BUFGCTRL | I0, I1 | O | CE0, CE1, IGNORE0, IGNORE1, S0, S1 |
BUFGCE_1 | I | O | CE |
BUFGMUX | I0, I1 | O | S |
BUFGMUX_1 | I0, I1 | O | S |
