pins driving global clock networks.
Regional Clock Network
There are eight regional clock networks (RCLK[7..0]) in each quadrant
of the Stratix II GX device that are driven by the dedicated
CLK[15..12]and CLK[7..0] input pins, by PLL outputs, or by internal
logic. The regional clock networks provide the lowest clock delay and
skew for logic contained in a single quadrant. The CLK pins
symmetrically drive the RCLK networks in a particular quadrant, as
shown in
