Modelsim simulation problem: altfp_mult floating point multiplier Megafunction

Thanks for you replies!

@FvM:

My problem is that i want the output to be 0X00000000 until the vlaid result is avaiable. I have cascaded many multipliers an adders, so anything other than '0' or '1' will mess up the whole simulation.

@gmpstr:

Thank you so much for that simple idea! If a reset the Megafunction for a couple of clock cycles, they behave like a want it. Thank you!
