LAB Interconnects
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, PLLs, M4K RAM
blocks, and embedded multipliers from the left and right can also drive
an LAB’s local interconnect through the direct link connection. The direct
link connection feature minimizes the use of row and column
interconnects, providing higher performance and flexibility. Each LE can
drive 48 LEs through fast local and direct link interconnects.
