Hi Samk,

It is possible to implement a waiting state using the state machine block. For reference, please look at the application example [here](https://www.plexim.com/support/examples?field_demo_model_product_value=1&body_value=All&body_value_1=2), titled “PLECS: Buck Converter with Constant On-Time Control”. In this example, the current compensator is implemented using a state machine block, and it uses “timer” events and a “waiting” state. I attached the write-up of this application example to this post.

Regards,Manu
