I am working through the following guide:
I’ve had no problem with steps 2 and 4, but I can’t get step 3 to work (BJT simulation). I’ve reproduced the exact same schematic as the screenshot provided in the guide under Eeschema, using only PSPICE devices, except the BC546 which comes from Transistor_BJT. All component values are identical to the screenshot too.
I’ve tried the three models with identical results (both links from the guide, and this one: https://www.diyaudio.com/forums/software-tools/278096-bc546-spice-model.html#post5587810). I’ve tried all permutations of “alternate node sequences” (i.e. pinouts, as described at step 4). I’ve simulated with both a ‘sin(0 1m 500)’ input and a fixed 0V input. Regardless of the input signal, the output is always a short swing in the pV range followed by a 0V flatline. I am using KiCad 5.1.5 (under Linux) and the embedded version of Ngspice (ngspice-31 i believe?)
Can someone help me figure out what I’m not doing right?
