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.
shows the direct link connection.
LAB Control Signals
Each LAB contains dedicated logic for driving control signals to its LEs.
The control signals include:
Local
Two clocks
Two clock enables
Two asynchronous clears
One synchronous clear
One synchronous load
