Tz50 Driving the Regional Network

The following figure shows the regional network clock sources graphically.

Note: The figure shows the regional clock sources driven from the periphery; some FPGAs have additional regional buffers that can only be accessed from the core. You use them by manually instantiating a GBUFCE primitive driven by the core and assigning it to the location of the RBUF

The PLL CLKOUT4 can only connect to the top (or bottom) interface.
