BUFGMUX and BUFGMUX_1
BUFGMUX is a clock buffer with two clock inputs, one clock output, and a select line. This
primitive is based on BUFGCTRL with some pins connected to logic High or Low.
Figure 1-8
available for BUFGMUX and BUFGCTRL.
X-Ref Target - Figure 1-8
Since the BUFGMUX uses the CE pins as select pins, when using the select, the setup time
requirement must be met. Violating this setup time might result in a glitch.
Switching conditions for BUFGMUX are the same as the CE pins on BUFGCTRL.
