Suppose that I have a requirement in an EARS form like follows:

While state1 = state_operational, when input1 = 1, the system shall satisfy output1 = 2 for at least 2 seconds.

1) Is there a way to express the interruption when the state changes? And what happens with the 2 seconds time in this case?

2) How can I express the "for at least 2 seconds"? I refer to this into the action column of requirements table.

Requirements are plane text. If you are trying to test requirements to show coverage you can use assessments to test that the temporal behavior of your signal. https://www.mathworks.com/help/sltest/ug/temporal-assessments.html
