So IF you have a signal being high for a number of time-ticks out of a total of time-ticks forming 360 degrees you'd have the second signal following the first with the same number of time-ticks high but 180 degrees later.
You'd have to declare:
out1: say 100 ticks high
put it low for 260 ticks
out2: also high for 100 ticks but 180 ticks later.
repeat this and that should be it.
This is a raw example just for the idea.
