Each LAB consists of 10 LEs, LE carry chains, LAB control signals, local
interconnect, 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
within an LAB or adjacent LABs, allowing the use of local, LUT chain,
and register chain connections for performance and area efficiency.
