Ah, seen it now, however there are no messages yet !

There is, however, a group named "Allspice", which is a group for users of all SPICE simulators. DaveD KC0WJN [email protected]> wrote:

Andy, Of course I installed version 24.0, and I was talking indeed about the problems I was having when trying to run my sims with parts this version did not have in its library. Carlos

Yes this is really a exciting feature for transient analysis of examples with behavioral sources. :-)But there is? a problem if i made only a .op simulation of a circuit with a huge amount of

I believe the latest KiCad works with LTspice, but the problems with version 24.1 might compromise that. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

I'm aware of there is a groups.io for KiCad, however I can't see a specific group for ngspice (which is the Kicad's simulator under the hood). Carlo.

It isn't, really, but someone familiar with both apps might advise you. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

Hello, I'm not sure whether this is the right place to ask about the difference seen in tube amplifier's transient analysis between LTspice and ngspice. The tube amplifier was the topic of this thread

Yes, I can confirm this does now work in 24.1.4, provided "0" isn't one of the model names, which I had inadvertently done in the example I uploaded. But when revisiting this, I note that it also

This is a good example for how ADI is indeed paying attention to the valuable feedback from this group. In LTspice 24.1.4, numeric parameters implicitely convert to strings. As a result, the old way

One of the exciting new features of LTspice 24.1 (which is the best thing since the invention of sliced bread :-) is that it compiles the math expressions of behavioral sources into highly optimized

Carlos, Andy I is correct when he mentions locations for different versions of LTspice. I still have both LTspiceIV and LTspiceXVII on my computer system. Both versions are in their factory default

Adding one more thought - Would I be correct to say that the "missing" parts models were devices that *you* had previously added to LTspice? LTspice *should* not have removed any models that had

Hi Andy, Re: .... /g/LTspice/message/157845.....? Great Post ... thanks. Ian

Carlos, Since version 24.0.xx is not the newest version, did you try just installing it, effectively as an upgrade to your previous version?? It might leave everything in place including your

Thanks John and Andy. I thought there might be an easier way that I was missing. But from my Google research and the tutorials I saw I started to guess my desire was hopeless. Carlos

What John is talking about, is moving your models into LTspice's own symbol and model directories.? Doing that is frowned upon and generally should not be used anymore.? Maybe that is what you did

Yes, of course. Copy them to a location visible to LTspice.? Preferably it should be either the working directory with your schematics, or one of your user-defined Sym. and Lib. Search Paths, if you

Probably you can, but it would make your version of LTspice unique and might compromise updates. Instead, make your own 'MyLibraries' folder, under C:\ or Documents,and put the libraries you want into

Is it possible to transfer previous LTspice libraries from previous versions and add to newer LTspice versions? For instance, opamps and discrete active parts models, like transistors, that are
