Hello, In vain, I searched its model (TDA2822) in the group’s archive and on the internet. It is suitable for 32 Ohm headphone with an electret microphone and 2*1.5V battery. I have one ear working

Ok, I'll try asking.. I uploaded both LTspice .asc schematic and ngspice .cir netlist including the libraries for subckts referenced. As you can check, .tran 100n 10m analysis gives quite different

Sorry, that was a misunderstanding. The above syntax was a proposal for a future change. This is about a compromise. The old way can't come back. I'm open for suggestions. And mod

No, that doesn't work, either, in any version. With or without a comma between "V(3,4)" & "BC848B_Ic_Vce_400u.inc" the same error results. Doesn't look like the file is being included.

Yes, this won't work anymore. Prior versions pre-process the input and replace the .include line with the contents of the included file and then parse everything all over again. 24.1 is very

I have many testjigs that import digitised datasheet characteristic curves. An example of this would be: This is used with a G-source called IB_400u, which in this case is the? Ic vs. Vce

I have uploaded an example schematic that shows 3 options for stepping MOSFET models: Stepping_Models_pre-V24.1_workaround

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
