Instead of guessing, use Task Manager to check the performance. You should be able to easily see which resource is being used the most. Are you sure the work PC has 128GB of ram? Specifically, which

David asked, "Aren't they in the folder you're working in by default?" LTspice also has a location for "Temporary Files".? Go to its Control Panel > Operation tab.? It's at the bottom of that tab.?

Actually, FFT and Inverse FFT are essentially the same algorithms, so the second FFT is really an IFFT, converting the spectrum back into a time-domain waveform. I expect that the .imp file is the

I don’t recommend opening it with a text editor. 11 lines of text, describing the file, 1 line “Binary:”, and 4 MB of … binary. Sent: Sunday, July 02, 2023 12:41 PM To: [email protected]

I didn't intend to do an FFT of an FFT, but that might have happened by accident.? A spectrum of a spectrum is a cepstrum, which has similar anagrammatic concepts such as quefrency.

John wrote, " but I've never seen an .IMP file before. " So you probably never did an FFT of an FFT before.? I think that is the only time you get such a file.? LTspice's Help recommends doing that

Well, I have done? a lot of FFTs in the past , and .FOUR, but I've never seen an .IMP file before. ====================================================================================== Best wishes

It is indeed an "Impulse response" file, the result of performing an FFT of the FFT's output.? Like regular .fft files, LTspice leaves it around for you to delete if you choose to.? If I'm not

Have you modified the settings in LTspice so that? temporary files and working files are in a folder on the ramdisk?

This is an impulse response output from LTspice. I think it is the FFT of an FFT done. You can delete it.

The problem with this is it won't contain anything from LTspice's distribution. We know that, over time, devices are added to standard libraries. But also devices are deleted - usually without

Try opening it in a text editor just for a look, or just try dragging it from Explorer into an open LTspice session - it would then be opened by LTspice as a text file. LTspice initially assumes

No, the first very basic mockup was done in a bash script, simply to get an idea how it should work. But anything for the masses has to be multi-platform. I'd not even considered Powershell. I don't

I have a folder named "Components", where I put the basic sims of individual devices. Each one has a folder with the .asc, .sym and model in it. When I want to sim a circuit that usees one of these

Isn't the normal way of doing this to create a 'Project' folder that automatically contains folders for each data type (i.e. each .extension) that can all 'see' each other? Like a PCB design project.

Hmm. interestingly, I happen to be working on a powershell script to do just that (although, I'm guessing yours would probably be designed for linux OS). I imagine, however, that there would have to

I just did a simulation of a simple active filter, to look at distortion of the filtered signal, and after LTspice has closed, it has left a file called 'Filter.imp' in the schematic folder. It's 4097

Yes, I write and tell them sometimes. But my voice isn't loud enough. Anyone that's been here long enough will remember Helmut saying all this over and over again. Another way that this issue could be
