Hi.
thank you for answering.
I want to save an electrical signal in my OptiSystem Project for further analyse ,in stl file format.
Now I understand my problem.
during simulation, from iteration 1 to 10 , this signal is Null(I connect an oscilloscope visualizer and see nothing! )
after iteration 11 oscilloscope visualizer shows that signal.
I guess my problem is because that Input signal of “Save Spice Stimulus File” cant be Null.
I think a trick to solve this problem!!!
I work with Optisystem 13.
