generate complementary digital signals with dead time between each pulse and controlled by duty ratio

I am to generate  two complementary digital signals using NI 9606 conected by RIO Mezannine Card to NI 9683 (Half Bridge DO).

I am able to generate the signals but I am not able to put dead time between high and low signal and also, low and high signal.

Requirement:

(1) When the first signal goes high and the second signal goes low, there should be a controllable dead time.

(2) Also when the second signal goes high and the first signal goes low, there should be a controllable dead time.

I am able to do requirement 1, but I am unable to fulfill requirement 2.

Please have a look at my VI and let me know how to go about satisfying requirement 2.
