Fast PLL Outputs

The corner fast PLLs can also be driven through the global or regional clock
networks. The global or regional clock input can be driven by an output from
another PLL, a pin-driven dedicated global or regional clock, or through a clock
control block, provided the clock control block is fed by an output from another
PLL or a pin-driven dedicated global or regional clock. An internally generated
global signal cannot drive the PLL.
