Unable to perform AC voltage parameter sweep #724
-
Hello, I wanted to do a parameter sweep of an AC voltage for a test circuit, but it gives an error. Do you know if my setup is incorrect? Here is the error:

I cannot reproduce this error. Everything works as expected on my machine using Ngspice-42. What Ngspice version are you using? The Ngspice-27 from Ubuntu-22.04 doesn't support variable sweep. |

Yes, it's better to upgrade the Nsgpice. The versions before 37 also don't support S-parameter simulation. |

It is a known bug. Every transient waveform from Ngspice may have different length, because the time step is adjusted dynamically. Qucs-S plotting engine cannot process a set of waveforms of different length in one plot. I am unable to fix this without a redesign of the plotting engine. There is no workaround. The AC simulation is not affected. |

You may use the tuner instead of param.sweep to investigate the parametric circuits in transient domain. |
