Usually the HDL languages don't bother trying to emulate these. You
simply recreate the behavior that you want and blamo, out pops a bunch
of gates that usually does what you want.

I would second the above. Also the cost factor will be a lot lower for
a bunch of diodes compared to programmable logic.
