What made your netlist confusing to me, where a schematic would have helped, is figuring out the interconnections between the subcircuits, and between them and the other elements. Having nodes marked

Agree, but it is teditious to debug and/or examine a *.CIR file. No one is interested in a .cir file. - as Rick sawreyrw said. No one will do that job for you. So if you cannot transform the *.CIR

scad3.ini is now named LTspiceIV.ini. I believe its location is $APPDATA$\LTspiceIV.ini. The exact location of $APPDATA$ is dependent on your version of Windows. On this computer, it defaults to

Hello. I once knew how to transfer the keyboard shortcuts from my desktop to my laptop of LTspice. I have searched for it and found instructions that say that a scad3.ini file is located in Windows,

Dear Fred Thank you very much for your answer. the reason that I use arbitrary model not a standard diode is that I cannot control temperature change for each solar cell in diode model. Furthermore,

Sorry I mis-typed, you probably want to leave v(inp) alone (don't reference it to 'ref') but you do want to change v(internode) to v(internode,ref). There still seems to be some other problem, though,

As you may know, Mike Engelhardt has said before that LTspice isn't going to be ported to another platform or OS. That would be a major undertaking. If there exists anything similar to Wine for Linux

At one time, T.I. and National Semi (which is now T.I.) had SPICE models for them. In a university project I should simulate and analyse the frequency If you mean crosstalk within a device (multiple

Hello Hamed, While I would also advise you to use a standard diode model instead of building your own, I may be able to shed some light on your difficulty. Note that your derived values for ISC and

Having used LTSPICE for some years now, I never satisfactorily solved this issue: I have some circuits that have essentially 0 gain, plotted on dB scales - I get 100's of dB on the vertical axis. I

I sometimes use a 'linear' representation of inductors to speed analyses. Try a ladder network of linear inductors and resistors. Just like in fitlering, you have to change the first and last

Hi Herbert A simple model would be an inductor in parallel with a resistor. Most ferrous cores behave well up to a cross over frequency at which the perm drops and they become very lossy. The loss

Did you know that a particular instance of a diode may have its temperature set independently of the general circuit simulation temperature such that the diode temperature remains fixed while the

Thank you very much dear friend( you did not mention your name) The fact is that here I cannot use the standard diode model while it is temperature dependent diode so I should mention the diode

Is there some reason you model must be so complicated and do you really need to reinvent the diode model? Couldn't you do something like the following and put all us, your fellow group members and

Thanks friends for your responses but the point is that converting this circuit to schematics will make it more confusing. actually the output should not have the distortion in -1.8kA ! and it should

Hi. You included TVS diode in parallel to the voltage source? Then, measure the diode current. If the source impedance is zero, the voltage limit is not. Put your project in the TEMP folder.
