Interconnect
LAB Local 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 blocks 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.
