XC4000: Use NODELAY attribute to get (fast) Input FF databook speed w/o delay
Solution
To skip the delay block on the input of the IOB flip-flops in the 4000 family of devices, attach a 'NODELAY' property to the flip-flop. The exact method of doing this will vary depending on the entry tool. See the appropriate user's guide for more information.
