How to Index waveforms with Step parameter values?
I've been stepping via Temperature (for example), getting say 20 traces in a single plot pane. How can I add the actual "step values" to the particular traces depicted? Thanks.

Thanks Andy for your guidance. I should be able to proceed forward based upon your explanation. I¡¯ll also see about joining the group properly to discuss LTspice issues. Samudra Haque N3RDX Sent:

Re: Strange character in error log - "¡ì"
I experimented with the new IGBT model and found it to be very bad. Unlike the VDMOS model, which works very well and can be adjusted to match the datasheet characteristics of most parts, the new IGBT

Re: Any method to convert LTspice schematic to autocad .dwg or .dxf format ?
A web search (Google) for 'convert emf to dwg' shows a number of hits. You can export schematics from LTspice as .emf files. Best wishes John Woodgate OOO-Own Opinions Only J M Woodgate and Associates

Hello Carl, Thanks for sharing an example with .model NIGBT. We have seen only a very few so far. The ¡ì character will be added, if a device defined with .model has not the correct character in the

Any method to convert LTspice schematic to autocad .dwg or .dxf format ?
Hi, : May I ask a question , is there any method to convert LTspice schematic to autocad .dwg or .dxf format ? I hope to convert those tasks, since sometimes after I spent time running simulations in

Re: Strange character in error log - "¡ì"
Hi. Cshunt = 1pF solves the problem. This adds 1pF to each node. In this particular case, this can be done because There are no subcircuits that would damage it. See what happens in the power supply!I

Re: Strange character in error log - "¡ì"
Carl, The special character "¡ì" is a character inserted by LTspice, one that is unlikely to be used by anyone. There are places where LTspice needs to concatenate names together. For example, when it

Strange character in error log - "¡ì"
I'm running a simulation with an IGBT. I get an error log entry "Fatal Error: Analysis: Time step too small; time = 2.44141e-011, timestep = 1.25e-019: trouble with nint:z¡ìq11-instance m1:z¡ìq11".

Re: How to include component values in LTSpice trace formulas
Thanks a lot that seems to do the trick! (needs further testing, but probably works) I've read the Func dot command page in the wiki several times, but didn't understand it correctly apparently...

It is best to upload files to the temp directory of this group rather than externally. (and the code example could have just be placed as in-line text in the message. Have you read the description of

Re: How to include component values in LTSpice trace formulas
First, sorry for "hijacking". In Message 3 (which led me here), John cited the help and the "general nonlinear capacitor" function of the C part in the schematic editor. So again, my question is, if

Joe, FYI, your uploaded schematic had nothing to do with the question you asked. "I have uploaded the spice value into the temp folder." Your schematic doesn't have comments either. Your reply said

Re: FFT
There may be some disagreement about the origins of LTspice, whether or not it was at all based on Berkeley's SPICE code, or if it is a complete write from scratch. It's my understanding (based in
