Unable to simulate ALTSQRT in ModelSim Altera

I wrote a small program to try out the altera sqrt ip. i included the module in a quick script i wrote, but when i try to simulate it, i get X values in some of the bit fields. I thought it might be ...

Hi, I tried that but didnt seem to change the result. its still driving the same output. The reset I've shown here is only for my logic which drives the input to the design. i dont even have any code that checks for that reset! also the reset itself isnt connected to the sqrt block.
