If I remember correctly, a while back this same topic came up. The raw files wanted to be saved in a different directory for "speed" purposes.

Yes, and that appears to be intentional.? ("Directory for .raw and .log data files")

I remember some of that discussion, and I think it involved .plt files too, but I might be remembering incorrectly.
So when you write "temp files" what are you referring to? I didn't think that ADI meant only down loaded update files.
They do, according to LTspice's Help.? Temporary files do not mean the regular output data files.? Those are not temporary.

I think you just remembered the wrong setting.? No problem about that.? Go to the Waveforms tab to find the one you want.

My recollection about "Reset to Default Values" is that might apply only to the tab that is currently selected when you click that button.

Thus, clicking "Reset to Default Values" when you are in the Operations tab, would not affect the settings in the Waveforms tab.

But my memory might be faulty.

According to LTspice's Help, the files that would be temporarily saved in the "Directory for Temporary Files", are files that are downloaded during a Sync Release update.? And only for that.? I can't see any good reason for wanting them saved in the current schematic's folder.

Agreed.
?
?
As far as I know, LTspice does not do temporary files while running a simulation.? It saves a .NET file before the simulation begins (which you might call temporary), and it saves the .LOG and .RAW and .FFT and .PLT files, but all these are always saved in the schematic's directory anyway - unless overridden by a different setting in the Waveforms tab.

Agreed. But it not in 24.1.4

Do you really need to change the "Directory for Temporary Files"?? I suggest probably not - and almost definitely not changing it to the current schematic's directory.

But...right now I need to figure out how to reset the destination back to saving them into the current schematic directory.

How can you tell?? You would need to catch it right after starting a Sync Update, and then hope that the temporary files it creates are visible.? IIRC, Windows is apt to create temporary files that you normally can not see from Windows Explorer, even with the "Show hidden files" setting enabled.? There's "hidden", and then there is "really hidden".
?
The log file is still saved in:
C:\Users\(username)\AppData\Local\LTspice\Temp
Hmm.? Well, that is new behavior.
?
Also the .LOG file is not a "temporary" file, at least not by my definition.? So it would not be affected by that setting anyway.

LTspice 24.1.4 - Limit function
If I run a schematic with limit function in 24.0.12:
?
b:u1:g_abmii22 u1:32b 0 i=v(u1:32)*(limit(((v(u1:31vdd1)-v(u1:vde))/(v(u1:31vdd1)-v(u1:31vdd2))), 0, 1))
?
If I run the same schematic with limit function in 24.1.4:
?
u1:BG_ABMII22 u1:32B 0 I=v(u1:32)*if(((v(u1:31vdd1)-v(u1:vde))/(v(u1:31vdd1)-v(u1:31vdd2)))<0,0,if(((v(u1:31vdd1)-v(u1:vde))/(v(u1:31vdd1)-v(u1:31vdd2)))>1,1,(v(u1:31vdd1)-v(u1:vde))/(v(u1:31vdd1)-v(u1:31vdd2))))
?
Both simulations were run with expanded netlist turned on.
?
I guess the expanded netlist format changed.
But did the "Limit" function change too?

Re: BSC0403NSATMA1 LT spice library file
Try Mouser's excellent product-finder to find
a near-equivalent that is not obsolete and has a SPICE model.
The BSC110N15NS5 might help.

Yes, of course that's true. Very strange that I never noticed before, as someone that uses a lot of underscore characters. Oh, well.
I think I forgot saying this before:? Underscores in the middle of names do not result in the overbar.? It is only when the underscore comes at the start of a name, after a space (or, as eT found, after a parenthesis or bracket), that you get the overbar in LTspice.
?
IIRC, in old days, some engineers used either an underscore or a slash character before a signal's name, to indicate that it was a low-true or "NOT" signal - especially in typed documentation when names were typed out.? But we drew schematics by hand and then it was easy to draw the overbar.
