Figure 2–43. Regional Clocks
Fast Regional Clock Network
In EP1S25, EP1S20, and EP1S10 devices, there are two fast regional clock
networks, FCLK[1..0], within each quadrant, fed by input pins that can
connect to fast regional clock networks (see
larger devices, there are two fast regional clock networks within each
half-quadrant (see
clock networks. All devices have eight FCLK pins to drive fast regional
clock networks. Any I/O pin can drive a clock or control signal onto any
fast regional clock network with the addition of a delay. This signal is
driven via the I/O interconnect. The fast regional clock networks can also
be driven from internal logic elements.
