IBUFGDS simulation model doesn't implement IBUF_DELAY_VALUE

For Spartan 3A and Spartan 6 (that I've looked at), the IBUFGDS primitive has a delay element whose delay is set by the generic IBUF_DELAY_VALUE. This generic takes a string whose value can range from "0" through "1" up to "16."

 

However, the simulation model does nothing with this value, other than to test that it is in range. Specifically, it does NOT actually model the chosen delay.

 

Is there are particular reason for this? Because I kinda depend on it for something I'm trying to do.

----------------------------Yes, I do this for a living.
