2–3:
Each LAB consists of 10 LEs, LE carry chains, LAB control signals, a local interconnect,
a look-up table (LUT) chain, and register chain connection lines. There are 26 possible
unique inputs into an LAB, with an additional 10 local feedback input lines fed by LE
outputs in the same LAB. 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
adjacent LABs, allowing the use of local, LUT chain, and register chain connections
for performance and area efficiency.
The LAB local interconnect can drive LEs within the same LAB. The LAB local
interconnect is driven by column and row interconnects and LE outputs within the
same LAB. Neighboring LABs, from the left and right, can also drive an LAB’s local
interconnect through the DirectLink connection. The DirectLink connection feature
minimizes the use of row and column interconnects, providing higher performance
and flexibility. Each LE can drive 30 other LEs through fast local and DirectLink
interconnects.
