Default value for capacitor instance initial condition

[mildspice]

Thank you @KSKelvin for the explanation.

Interestingly, for the inductor the default value of IC is “none” (matching your suggestion) while for the capacitor it is “0.0”.

Also, I found this reply from Mike Engelhardt from July 2023 talking about the use of the UIC option of the .tran command

Initial conditions not working

UIC has different meanings to different simulators. To Berkeley SPICE, it means don’t do the .op, i.e., it’s like the PSpice skipbp. However, in Berkeley SPICE, that is when instance initial conditions are used. I might change the QSPICE behavior to be more like the PSpice behavior because that is more common. Anyway, as of today, just remove “uic”: [image] If you want to use UIC, you have to put the condition on the instance. But then the .ic V(…)=… statements are ignored: [image]

If the UIC option is used, what ICs will be used for the components without explicitly defined ICs? Will the defaults be used - “none” for inductors and “0.0” for capacitors?
