Cannot Simulate Altpll IP using ModelSim

I'm trying to simulate Altpll IP using ModelSim. Even tho I mapped the library to the work location, I still see Hi-Z signals on Waveform.

Here's the steps I have followed:

1) Change Directory to where my source files exist.

2) Map to library. I chose the path of altera_mf library and mapped it to the work.

3) Refresh library, compile and simulate.
