Notes:
1.
TBCCCK_CE and TBCCKC_CE must be satisfied to assure glitch-free operation of the global clock when switching between clocks. These parameters
do not apply to the BUFGMUX_VIRTEX4 primitive that assures glitch-free operation. The other global clock setup and hold times are optional; only
needing to be satisfied if device operation requires simulation matches on a cycle-for-cycle basis when switching between clocks.
