Thank you kaz for being helpful.
I must apologize for I failed to mention that my project is basically a control system experiment of a simple process. It is made up of a Finite State Machine only (with exception of the
async signal I mentioned earlier, which is the only signal that is not a part of the FSM).

Since your design is just few signals you can enter overall toggle rate.
--- Quote End ---
With the toggling of the
state flipflops being absolutely dependent on events occuring in the process and its previous state, the toggle rate, to me, seems indeterminable.
I am saying this because I can't ascertain what state the flipflops will transition to and when the transition will occur since it is dependent on real-world inputs. The flipflops will maintain a certain value (say "0101") for as long as an event that triggers a transition to another state does not occur, and when an event occurs, it may transition to, say "1111" or "1011" or "1010" or ..., depending on what event occurred. I think you can guide me better if I paste my code so you take a look at it.

you can enter toggle rate in powerplay r I think yu can also enter in quartus project settings
--- Quote End ---
Please, how do I calculate the toggle rate in this scenario.
