.STEPping a .WAVE file output
开云体育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 illustrates the intent, but not? surprisingly, errors off on the last line: ? .step param stp 1 6 1 .param Vcon table({stp}, 1,-2, 2, -1, 3, 0, 4, 1, 5, 2, 6,3) .wave {Stp}.wav 16 44.1k V(Out) ? Any suggested better syntax? I’ve tried several… Thanks! ? Dave ? |
开云体育Exactly what error message do you get? On 2025-03-24 15:42, Bell, Dave via

开云体育I haven’t tried that, Andy, will do. Running XVII ? “A C++ exception with the message: ‘invalid .stoi argument was thrown during simulation, which indicates a bug in LTspice. Please report this incident.”

开云体育Well, that is a very significant error

开云体育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 On 2025-03-24 17:03, Bell, Dave via

开云体育T does work, as you suggested, with *just* the number as filenemae. OK for a few files to rename, like this, but if I wanted to make a lot of runs, it would be a pain. ? Thanks, Dave ? From: [email protected] <[email protected]>

开云体育Very nice! I used to have a good mass rename/redate tool for Windows, but it’s been a while. ? Thak you! Dave ? From: [email protected] <[email protected]>

I have tested the following methods, plus the *.bat running under Windows OS. ? " .step param stp 1 6 1 " --> it generates the file 1, 2,...,6 ? Then run the batch file, as following: (save it to file & name it to ***.bat) " @echo off " ? Not sure if that's my naive, I tried the website of Analog Device, it doesn't release LTspice 24.1.6 yet.
? Have a nice day. Best regards. |

Oops, I found the ".step + ,wave" method only works in LTspice XVII, not supported in LTspice V24.1.5.
In V24.1.5 I , it only creates a file named "{stp}". ? Best reards. |
