I've cloned the code again from scratch, rebuilt it with slightly different configure parameters and the error is gone. Thank you!

Not sure why it showed the percentages at that time, but basically this is the output: Note: can't find init file. ngspice-37+ : Circuit level simulation program The U. C.

Thanks Holger, sure, I've attached the output when I run ngspice test1.cir: On Sat, Sep 10, 2022 at 3:27 PM Holger Vogt h_vogt@users.sourceforge.net wrote: I am also not meeting any problem running your circuit on ngspice-37+, git branch pre-master.

Hi Marcel I'm using version 37+ at commit 0faf386d45521f7ed82f621266b3990adc982b50 built from source, for me the simulation gets aborted when t=15ms. If I reduce R2 to 1k, then the simulation completes without errors. However this is not great because the simulation successful completion should not depend on specific resistor values (unless there is a short circuit) On Sat, Sep 10, 2022 at 12:37 AM marcel hendrix mhx_at_sf@users.sourceforge.net wrote: I see no problem. Are you using a recent NGSPICE?...

Hello I'm trying to use ngspice with a very simple circuit below (I gave up a few years ago but may be more lucky now). I'm puzzled by the following error: doAnalyses: TRAN: Timestep too small; time = 0.014842, timestep = 4.83105e-15: trouble with npn1-instance q.x1.q1 I've also looked for other free spice alternatives that run on linux but couldn't find any up to date (I've seen qucs and gnu-cap, but seem very old), any recommendation? This is the circuit that I wrote. I believe that the error message...
