I have downloaded eSim 2.0 for windows.I am using Windows 10 (64 - bit). It is working perfectly for transient analysis. But for AC analysis, for the selected eSim_AC source, the parameters (like amplitude and phase) can't be set because when I convert the kiCad circuit to NgSpice, for AC analysis, only the frequency settings window is shown. The source window shows blank. But, the message of successful convertion is appearing.The simulation also shows successful message but the plots are showing 0 V for the entire range of frequencies. Also, the netlist of NgSpice shows 0 V for the source. Can you help me why the window for AC Source is showing blank? Please help me to overcome this technical problem.
