Logic Array Blocks  
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, 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. Figure 2–4 shows the DirectLink connection.

LAB Control Signals  
Each LAB contains dedicated logic for driving control signals to its LEs.  
The control signals include two clocks, two clock enables, two  
asynchronous clears, a synchronous clear, an asynchronous preset/load,  
a synchronous load, and add/subtract control signals, providing a  
maximum of 10 control signals at a time. Although synchronous load and  
clear signals are generally used when implementing counters, they can  
also be used with other functions.
