adjacent LE for fast sequential LUT connections within the same LAB. Register chain  
connections transfer the output of one LE’s register to the adjacent LE’s register  
within an LAB. The Quartus® II software places associated logic within an LAB or  
adjacent LABs, allowing the use of local, LUT chain, and register chain connections  
for performance and area efficiency. Figure 2–3 shows the MAX V LAB.
