So i want to state 1 the first time with the condition [Rising== 1 && n == 32] and then re enter it everytime from state 8 with the transition [Rising== 1 && n == 1]. Would this work?

When i implement this design using HDL coder and download it on the FPGA i don't see any output signal. I output my signals to simulink from state 8.

Have you verified your design by simulating the Stateflow chart in Simulink? Is the output what you expect?

Do you want the condition for the transition from State_8 to State_1 to be [Rising== 1 && n == 1] or do you want to the action of the transition to be setting the value of Rising and n ?

Hallo I want the condition for the transition from State_8 to State_1 to be [Rising == 1 && n == 1]. But later i checked it on the simulink state flow chart and it works fine.

[Rising == 1 && n == 1] condition was used for entering State_8 as well as for exiting State_8. This makes State_8 to be active only for 1 task cycle. This could be the reason why you are not seeing any output from State_8.
