The LAB local interconnect can drive all eight ALMs in the same LAB. It is driven by
column and row interconnects and ALM outputs in the same LAB. Neighboring
LABs, M512 RAM blocks, M4K RAM blocks, M-RAM blocks, or digital signal
processing (DSP) blocks from the left and right can also drive the local interconnect of
a LAB through the direct link connection. The direct link connection feature
minimizes the use of row and column interconnects, providing higher performance
and flexibility. Each ALM can drive 24 ALMs through fast local and direct link
interconnects.
