Outputs Low Power Clock Fanout

XA Artix-7 FPGAs Data Sheet: Overview (DS197)

In each 7 series FPGA, 32 global clock lines have the highest fanout and can reach every flip-flop clock, clock enable, and set/reset, as well as many logic inputs. There are 12 global cl ock lines within any clock region driven by the horizontal clock buffers (BUFH).
