Simulating Networks-on-Chip (NoC) with OPNET

[pantic]

Hi everybody

I'm currently using OPNET for simulating Networks-on-Chip (NoCs) with OPNET. I know that it's a bit difficult but I hope I can obtain some good results.

My problem is the following: As far as I know, you have to build a state machine in each process and define which functions you want to execute on each state. When a function is being executed, there are no other functions executing, that is, it's like a blocking process. Because I want as much dynamism as possible, I'm trying to divide all my functions into small ones and putting them in different states. My problem is that I don't know how to make a transition from one function to the others, because there is no interruption at all. There is no packet arriving or no packet being transmitted.

For example: Suppose I want to execute the following algorithm in state A:
A=B+C;
if (A>10) execute function X else execute function Y

If function X is in state X and function Y is in state Y, how can I make the transition from state A to X or Y depending on the result of the addition?

Thanks in advance and kind regards
