Hi Ludovic,
If I recall correctly, when you run an analysis different than
transient, ngspice will not return any data when you ask for currents.
There is also another related line:
void NETLIST_EXPORTER_PSPICE_SIM::writeDirectives( OUTPUTFORMATTER*
aFormatter, unsigned aCtl ) const
{
// Add a directive to obtain currents
//aFormatter->Print( 0, ".options savecurrents\n" ); // does
not work :(
The directive is described in ngspice manual [1, 15.7.1]. Perhaps it is
fixed in ngspice-27, I have no idea. Try commenting out the condition
that prevents listing current signals for analysis other than transient
and see if you succeed.
Regards,
Orson

Hi all,
i try to create a patch to adding several improvment of eeshema simulation.
My first goal is to draw BJT caracteristics (like
https://www.st-andrews.ac.uk/~www_pa/Scots_Guide/info/comp/active/BiPolar/IcVce.gif)
with a simplest circuit in attachment.
I had beginning to work on this improvment but in the file :
/kicad/eeschema/dialogs/dialog_signal_list.cpp
in method :
bool DIALOG_SIGNAL_LIST::TransferDataToWindow()
there is a strnage comment :
// For some reason, it is not possible to plot currents in any but
transient analysis
If someone can give me some informations ?
