How can I change a parameter in my simulation in the after sometime of the run time ?

I have simulation model that will be run for 5 sec. I want to run my simulation for 3 sec, then change some parameters in my model and pause the run to end the remind 2 sec. How can I do it by fast way? I know there is a step forward to do it for each step but I need faster way.

To change the parameters in a model after x sec we need to pause the model when the Simulation time reaches to x sec

To do this we can use pause simulation using Assertion block Model in the top model

refer to the below documentation for how to create a pause simulation model using assertion block

https://www.mathworks.com/help/simulink/ug/controlling-execution-of-a-simulation.html#bq0ht63

In the Assertion block dialog box, clear the Stop simulation when assertion fails check box. Enter this command as the value of Simulation callback when assertion fails:

set_param(bdroot,'SimulationCommand','pause')

whenever the simulation time reaches to x sec it will pause the model and then user can change the parameters and continue the simulation.
