Helmut Is there a way to optimize on 2 or 3 variables and plot results like you did? i.e. Ton Tperiod R of the inductor for example? Thank you LTspice@...> wrote:

Hello Sam, I have additionally uploaded your example with MEASURE to the Temp-folder. transformer2_meas.asc Best regards, Helmut

Helmut Thank you. That is really good. LTspice@...> wrote:

John, Andy, - I suddenly stopped getting any messages from the list about the same time as that change. Checked to see if somehow the group got added to the yahoo spam list, nada. - I did change to

Hello Sam, This is wrong. See the correct version below. PULSE(0 10 5u .1u .1u {Ton} 1m) .step param Ton 2u 10u 2u .meas ampx max V(out) Run the simulation. View -> SPICE - Error Log Right-mouse click

Hello, No. Most of the parameters are the same, but especially HSPICE has often additional parameters. I vaguely remember that Spice programs can have different equations to calculate Weff and Leff,

Hello, I don't understand your log-plot. May be you simple asked for the step response of RC-circuits. .param tau = 0.2 V = 5*(1-exp(-time/tau)) Best regards, Helmut

I've uploaded 2 files to the Temp folder: curve_exp.jpg curve_log.jpg To get the exp curve in curve_exp.jpg I used: Value: V=5*exp(7*(time-1)) in a Behavourial Voltage source. It gives an exponential

Hello, I am getting confusing hints from search results: .. So a mosfet "level" is a way to model a mosfet using a set of defined parameters. (?) There are many so called "levels" and there have been

Hello, You could use the command from the menu Plot Settings -> Autorange Y-axis The shortkey is Ctrl-y Best regards, Helmut

(1) Choose any plot, drag a rectangle over it all, then all plots get same time axis limits. (2) Doing this with "Manual Limits" only zooms the plot selected (not all). So: What I'd like to be able to

Hello analogspiceman I'm not denying that your library works (I have used it a few times, successfully) or that a quasi-real transformer can not be built around the Chan core, but I have never used it

Hello Vlad, a transformer has multiple windings, but only one core (which is the only nonlinear part). That is why LTspice does not allow coupling between saturating inductors (either Chan or

Kevin replied: ? "? PULSE(-6 6 0 5m 5m 1p 10m)" That is how I'd do it too. Except that I probably would have used 0 rather than 1ps, because the on-time Ton is allowed to be zero. The waveform is

Hello guys, I tried so hard but i can't do that. Can anyone send me PWL code of -6 to 6V 100Hz trianglular wave. Thanks a lot. Regards, Mete

Hello Sven, After you have decided which plot(s) is the best, you can plot only one or a few of them using the @ selector. V(out)@12 V(out)@23 Best regards, Helmut

Hi John, I want to analyze just one signal point in 27 variations. Just to understand which influence have my 3 potentiometer in 3 different positions. Helmut's way works great. Even if I only have 4
