How to simulate the SDRAM IP core with modelSim?

Hi,

I want to use the sdram chip of my DE2-115 Board (cyclone IV E) to store data. So, I created the sdram controller using the the sdram ip core of Altera in plattform designer. During the generation of hdl files in plattform designer, I checked the case to create the functional simulation model. Now I want to simulate it in modelsim but I don't know how to do that.

I tried to load the created .sip file in Assignment->Settings->EDA...->Simulation as testbench file but when I launched the RTL simulation I didn't see any waveforms on windows.

Thanks very much.
