Logic array blocks (LABs) contain groups of LEs.
Each LAB consists of the following features:

The local interconnect transfers signals between LEs in the same LAB. Register chain
connections transfer the output of one LE register to the adjacent LE register in a LAB.
The Quartus II Compiler places associated logic in a LAB or adjacent LABs, allowing
the use of local and register chain connections for performance and area efficiency.
