PLL Configuration problem on ModelSim 6.6d

Hello, I’m currently working on a project where I have to use a PLL. After having done the configuration and the compilation on Quartus II 12.1sp1 Web Edition, I then run a simulation (gate level)...

To be more specific the goal of my project is to do 48 measurements in a wire, but during the simulation of the software when it gets to these 48 measurements, all the clocks stops suddenly.

This is the screenshot of the RTL simulation (which works fine):

I don’t know if it’s a problem in the software or a problem of configuration in Quartus II.
