You mean recursion? Your question is not clear to me, please explain what you want in more detail, preferably adding the code that you tried (correctly formatting it with the {}Code button).

main module trigger 2 function module. and then each function moodule run by stateflow and its stateflow call the child function module. all function call system have 5 depth. I can simulate this code but when I generate code, pop up loop problem on the log. so I tried to add unit delay block on loop code so theatit was fine. but result of this code is not my purpose. Could you suggest to any good solution to my code. if you have a more details about my question. plz give me a mail. [e-mail]
