Re: .STEPping a .WAVE file output
The failing stoi function expects an integer during parsing. Maybe 44.1k should be 44100 ? Or the file contains non-integer values where a integers are 'required' (expected). Arie

Re: .STEPping a .WAVE file output
It might depend on your LTspice version.? What's yours? Did you try ".wave {stp} 16 ..."?? That is, remove the ".wav" extension from that command.? Then add it manually, in Windows. What error

.STEPping a .WAVE file output
I want make multiple runs of a model which will output a waveform to a .wav file. Each run will step a parameter, all of which works as intended, except, I need to change the filename each time. This

Re: LTspice AKO
Unfortunately, in this specific case it is screwed up. It's a bug that will be fixed in 24.1.6 (coming this week). Best Regards, Mathias

Re: LTspice AKO
To clear, V24.1.x didn't screw up the AKO feature, as such - it still worked. The actual problem was with the model name not being recognised when AKO was being used with the resulting numeric "name"

Re: LTspice AKO
I had already checked that it does work even when an error is reported. 24.1.4 gave the same current as 24.0.12 in a .OP analysis, even when it reported the error. I doubled-checked by changing one of

Re: Sawtooth waveform by simple BJTs, but dips at the top.
I'm using ako: with a trailing (field) separator, as written in "General Form" in MicroSim's PSpice reference manual (as far as I remember, MicroSim introduced ako:). But in the corresponding example,

Re: Sawtooth waveform by simple BJTs, but dips at the top.
The glitch was a combination of both things.? If I remember correctly, the path from C2 to D1 had the larger effect, but removing only that did not eliminate the glitch unless the capacitance in Q2

Re: Sawtooth waveform by simple BJTs, but dips at the top.
I added this '.model TM1 ako: 2N3904 ?npn Cje=0', and changed the value of Q2 to 'TM1'. It didn't run out any error message. I guess the syntax is correct, though not take effect to eliminate the

Re: LTspice AKO
The simulation runs but I'm not confident its using the proper JFET parameters because it doesn't show them when it produces the error. It may be using JFET defaults.

Re: LTspice AKO
It does work for JFETs. It works in 24.1.4 and 24.0.12. In 24.1.4, you get an error message in the logfile, but it still works. I don't have 24.1.5 installed yet. The NJF() is superfluous. You already
