Information

Timer that starts at the initial time with a value of 0, and gets reset each time the input signal switches to false.

For example, if the simulation starts at t = 10 and at t=11, the input becomes false, then the timer outputs y=t-10 for t < 11, and y=t-11 afterwards, unless the input becomes false again.
