MultiTrack Interconnect  
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 2–11  
shows the LUT chain and register chain interconnects.

The C4 interconnects span four LABs up or down from a source LAB. Every LAB has  
its own set of C4 interconnects to drive either up or down. Figure 2–12 shows the C4  
interconnect connections from an LAB in a column. The C4 interconnects can drive  
and be driven by column and row IOEs. For LAB interconnection, a primary LAB or  
its vertical LAB neighbor can drive a given C4 interconnect. C4 interconnects can  
drive each other to extend their range as well as drive row interconnects for column-  
to-column connections.
