The local interconnect transfers signals between LEs in 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 Compiler places
associated logic within an LAB or adjacent LABs, allowing the use of
local, and register chain connections for performance and area efficiency.
