Preliminary Information  
Cyclone FPGA Family Data Sheet  
Cyclone devices include an enhanced interconnect structure within LABs  
for routing LE output to LE input connections faster using LUT chain  
connections and register chain connections. The LUT chain connection  
allows the combinatorial output of an LE to directly drive the fast input of  
the LE right below it, bypassing the local interconnect. These resources  
can be used as a high-speed connection for wide fan-in functions from LE  
1 to LE 10 in the same LAB. The register chain connection allows the  
register output of one LE to connect directly to the register input of the  
next LE in the LAB for fast shift registers. The Quartus II Compiler  
automatically takes advantage of these resources to improve utilization  
and performance. Figure 10 shows the LUT chain and register chain  
interconnects.
