Re: Issue with Nexperia BUK7S1R0-40H PET LTspice model
That is possible, but I think not likely.? By my read, the whole purpose of that Application Note is to show you the results of SPICE simulations.? Therefore, I think none of its plots were from

Re: Issue with Nexperia BUK7S1R0-40H PET LTspice model
This is a minor oversight (aka bug) in LTspice. It can't decrypt the file. You can clearly see this from the error messages in the log. Will be fixed in 24.1.6. Meanwhile you can work around it: open

Re: Brady Ridgway's Fuzz_Face (guitar "fuzz" circuit) simulations
One more thing to mention here: Because LTspice finds the lack of a load (DC path) connected to node Vout, it "corrects" the omission by adding a small conductance (large resistance) there.? It has

Re: Schematic drawing issues
Most modern TVs use algorithms designed to smooth imperfections in the video source material.? They help reduce the appearance of "grain" and similar noise.? Such a smoothing algorithm might

Re: Brady Ridgway's Fuzz_Face (guitar "fuzz" circuit) simulations
Brady, Here's a better explanation for the difference you saw. Plot the voltage at the top of R1, which is the supply voltage for the fuzz circuit. In the "original" circuit, it stays steady at -9.000

Re: Issues running LTspice as a batch service
Ok I tried it with a normal windows process leveraging the cli (not spicelib) and it works. So the entire problem was passing a .asc instead of a .net file.

Well, no, I meant 'somehow', because I am not sure that it's possible to actually alter pixel size. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

Re: Schematic drawing issues
Ah, yes. I was playing with it at quite a high magnification, where the anchors/handles are fat circles, easy to grab. Don't have to zoom very far to make it impossible to point-to-grab a hand

Afraid it is automated. The script that changes the version label runs some time later in a batch process, after the file is uploaded. Lags by a day or so. You can also use Check for Updates in

Yup, version 24.1.5 is the one that's there, identified as 24.1.4. I already let Analog Devices know that they have to update their webpage to show what you are actually downloading. Andy

Also, there doesn¡¯t appear to have been a 24.0.15; the last one listed is 24.0.12. I can run the uploaded .ASC with 24.0.11. -- This email has been checked for viruses by AVG antivirus software.
