I want to model the behaviour of a circuit in response to 'pushbutton' actions by a user. That is,
- Initial state;
- Simulate momentary button press & new state following;
- Likewise with a different button.
I haven't used NGSPICE for a looong time, and this sort of thing wasn't something I studied even back then. I haven't found any way to to this, or even to search properly for it, so any suggestions/help/links will be very much appreciated.
