PWM on 7i85s

Hi,
I would like to attach a laser module to my machine. Connect via PWM from the 7i85s. Unfortunately I am not able to write a bitfile. In addition, I am already far from the standard with my configuration. Does anyone have a bit file for the 7i76e with 7i85 7i85s and one PWM connection.If someone has a better idea let me know. At the moment I don't know how I can control the laser, but I think PWM is quite good.
Thanks in advance
Chris

PWM on 7i85's last step pin

Hi Peter,
Thank you so much. My configuration is on P1 7i85 and on P2 the 7i85s. I think the config is only a 7i85s on P1 right?
I once painted it on

7I76E with 7I85 on P1, 7I85S on P2, last step pin on 7I85S=PWM

Thank you for helping me.
