All you have to do is to change the installation location, from: C:\Program Files\ADI\LTspice\ ..which is the default, to: C:\Program Files\ADI\LTspice 24.1\ LTspice 24.1 will become the default

Hello Jim, When you install 24, the installer will change all pointers in the registry. After installation double-clicking any .asc, .asy, .net, .plt etc... will cause 24 to open. Therefrom, the only

Yes. Some people have even more versions on the same computer.? XVII and 24 store their working files in different places on your computer. Don't be tempted to make any changes to files held within

I currently have LTspice 17.1.14 installed on my Windows 10 computer.? Can the latest version of LTspice 24 be installed without uninstalling LTspice 17? Thanks

Since limit() always has been implemented this way with if() functions, convergence isn't affected because there is no change. Unfortunately it also means your efforts were in vain. Best Regards,

Hi Mathias In the past, I always tried to avoid if() statements to prevent convergence issues, and often used LIMIT to wrap if() statements. So I was concerned on how this re-write would affect

Mathias, ok will take a look at this Larry

If you consult the help on the topic of sub-circuit instantiation (LTspice Simulator -> Circuit Elements -> X. Subcircuit) you'll see that this is indeed possible. Best Regards, Mathias

On the contrary. LTspice works just fine, better than ever. The error is in your contradicting PWL numbers, as the error message says. The help contains a detailed example for this. If in doubt, write

There appears to be a bug in LTspice Version 24.1 that is still present in V.24.1.4. The Repeat/EndRepeat directive in some PWL source directives throughs an error. See my uploaded example file

I understand you can step .model files but can you step two mosfets that use the .subckt Larry

That should not be the case. There is no special treatment of the number zero. Can you provide a test case that proves a problem? Works just fine over here. Best Regards, Mathias

Depending on what those differences are, it might or might not be ideal to ask here.? There are not a lot of group members here who use both programs, but there are a few.? Some?have asked

I think you missed the context of earlier messages. The numeric .STEP'ed parameter is silently converted to a string as a "workaround". To use this directly, still requires the AKO: syntax. The new

ngspice has its own mailing list.? It is still current as of 2025.? It is hosted on sourceforge.net. There is one list for Users, one for Developers, and one for reporting Bugs. Andy

Carlos, Yes I understand that.? But are they parts that CAME with the older version, or are they parts that YOU added to the previous version? People often forget that they added models to their copy

Can LTspice24 (vers. 24.1.4) .STEP through non-numeric parameter values? If it can .STEP only through numeric parameter values, then how does it eliminate the need to rename the models? Andy

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
