I/O Structure  
Fast I/O Connection  
A dedicated fast I/O connection from the adjacent LAB to the IOEs within an I/O  
block provides faster output delays for clock-to-output and tPD propagation delays.  
This connection exists for data output signals, not output enable signals or input  
signals. Figure 2–20, Figure 2–21, and Figure 2–22 illustrate the fast I/O connection.
