simulation with modelsim from dsp builder

Hi everyone,

I'm using DSP blocks to implement my design.

simulation with simulink was successful but when I want to simulate with Modelsim I always have no outputs. when I compile with signal compiler the compilation is successful too.

Is anyone have any idea about the cause of this problem;

and is there a way to transform the input files from simulink (.mat files) to .vw files in order to try simulating with quartus II
