Each LAB consists of 10 LEs, LE carry chains, LAB control signals, a local
interconnect, look-up table (LUT) chain, and register chain connection
lines. The local interconnect transfers signals between LEs in the same
LAB. LUT chain connections transfer the output of one LE’s LUT to the
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
associated logic within an LAB or adjacent LABs, allowing the use of local,
LUT chain, and register chain connections for performance and area
efficiency.
