Regional Clock Network
There are eight RCLK networks (RCLK[7..0]) in each quadrant of the Arria 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
Figure
