Then, check the output of the counter for the 0 condition (all bits are zero), and if so, output a 1, otherwise, output 0 (NOR logic)
Voila, you have a signal that pulses (positive edge) every A*(fpga clock period) seconds.
Also, make sure you feed the correct voltage ito the stepper driver :)
EDIT: I guess I assumed you needed something that would move the motor at a given speed. If this isn't what you wanted, post some more details.

Edit: Just read that data sheet... Seems a little pointless to me, since it doesn't really take much to just do it yourself. It says you can connect that straight to a stepper motor, but since it can only supply 350mA, you're only going to be able to use a very small motor, or you just won't get any torque.
