Problems combining subsystems out of ModelPrim-Blocks

Hello, I'm using the DSP Builder Advanced Blockset to design the current control of an AC/DC converter. I separated the hole control algorithm in small blocks (subsystems) out of ModelPrime Blocks. I simulated all of them in Simulink and in ModelSim. All the results where the same. Then I put all the blocks together to get the hole system working. In Simulink everything is fine and it´s working like excepted. But the system doesn't work in ModelSim. And at the real hardware it isn't working at all.  

 

Where the difference between Simulink and ModelSim comes from? How I get the model working on real hardware?? How can I fix such issues???
