Subsystem to monitor the change of three inputs

I am trying to design a subsystem to monitor the change of three inputs. If one, two or all of the inputs changes values I want the simulationto pause. If none change I want the simulation to continue and so on. I was thinking of using a triggered subsystem but I am not sure how to think f it logically?

Hi,

You can check whether the value has changed from the previous time-step using delay blocks.

If the signal is discrete then you can use unit delayblock.

If the signal is continuous, you can use transport delay block.

Then you can add logical operations to check you conditions and to pause the simulation you can use assertion blocks. You can refer to

Hope this helps!
