Re: Parts Number Re-numbering
I use reannotate when 'polishing' schematics for technical articles or documentation of simple specialist test equipment.

Re: Parts Number Re-numbering
Such an option would be better than the chronological one, which makes no sense in terms of schematic reading. But it won't work for schematic layouts other than two or more rows of symbols or two or

I guess this is the reason fo the ¡°Reannotate¡±, shift+ctrl+alt+R, last gasp measure. I think that might be currently the only ¡°useful¡± application of this feature: just erase my numbering

Re: How to create IEC 61000-4-5 surge waveform in time & s behavioral ?
Hi, Marcel: It's not about courage, it's about truth of math. Besides the means mentioned previously. All I can find the relation is 'laplace(exp^(at)) = 1/(s-a)'. That's why I can't understand.

Re: How to create IEC 61000-4-5 surge waveform in time & s behavioral ?
Mentioning ChatGPT and MATLAB in the same sentence takes courage? I am quite sure MATLAB did not tell you how to *solve* the direct question, it only provided the *means* to find an answer. -marcel

Re: No recent files list with an empty window
The recent files list is stored in LTspice.ini. If you just upgraded from 24.0.x, you might find the old LTspice.ini wherever it would was stored - usually %APPDATA%/local/roaming/. If you're unlucky,

Re: How to create IEC 61000-4-5 surge waveform in time & s behavioral ?
Hi, Marcel: Thank you for the sharing. One thing that's strange is, the coefficient of 's' seems much different than that converted by ChatGPT or Matlab. "1/3.5e6*s + 1" vs. "s + 3.5e6" & "1/0.14e6*s

I added two photos that show how to construct the waveform both in Simulink and SPICE. ( Photos directory /g/LTspice/album?id=301365 ) The key problem is that neither Simulink nor

Hi, Tony: Thank you for your update. you are so kind. For a little while, I was worried that the new version will bring new issue of those 'Don't look up' problems. You give me hope. I am grateful.
