Question: how does the "edge with init" in boolean of signal blocks work?




as the cuts show,  i build a simple  system to check how does the "edge with init" work? The switch is "ideal opening switch". the rising edge is always "0" while the voltage is always 1v, it seems that the "edge with init" doesn't work. Please give me some explaintion of the problem.
