Why do stimulators in my waveforms dissappear during simulation?
You probably had more than one waveform file with stimulators open when the simulation was running. Please note that when simulation is running, simulators from different waveform window can simutanuously drive the signals. This can lead to confusing results when you assign different simulators to the same signals or in situations where you unintentially drive signals from nonactive waveform window. We suggest you always follow the following two rules regarding waveforms:
Always close an unwanted waveform windows before simulation
Save or edit waveforms only if the simulation is not running
