Hello ykarata1@ford.com.tr,
I see that you are using that enable block, which as far as I understand you expect to enable the execution for that subsystem if the signal is set. It should behaves similar to the if statement, right? I don't know how this block behaves under C code generation, so this requires a look in the generated code.
In this case can you try replacing the "enable" logic with an if statement one? Basically to call the subsystem when the input signal is set?
Hope this helps,
Marius
