Regional Clock Network  
There are four regional clock networks RCLK[3..0]within each  
quadrant of the Stratix GX device that are driven by the same dedicated  
CLK[7..0]and CLK[15..12]input pins, PLL outputs, or transceiver  
clocks. The regional clock networks only pertain to the quadrant they  
drive into. The regional clock networks provide the lowest clock delay  
and skew for logic contained within a single quadrant. The CLKclock pins  
symmetrically drive the RCLKnetworks within a particular quadrant, as  
shown in Figure 4–42.
