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.
