Yes, it was a missing closing parenthesis. Puzzling that PC would not complain by Mac OS would. Thank you all for helping. Roman

I have circuit which uses: .func myf(nom,tol) (nom+nom*(gauss(tol/5)) and a resistor which has a value {myf(400,0.1)} Besides these two I have a voltage source and I can simulate this circuit on a PC.

This was the same file. I use virtual PC Parallels running Windows 11.

I rebooted my Mac and it LTspice displays it correctly.

I am running AC simulation on my Mac and the plot will not exceed 1 MHz even thought the .ac card is specified to run 100 meg. .ac dec 20 1 100meg I ran the same file on a Windows 10 and the AC plot s

I have PC version running on Mac under Parallels in Windows 10 and FFT works like it supposed to as described in your email. This is not the case on Mac. In Mac version if I want to add a waveform it

In my simulation I wanted to view FFTs for three waveforms and it will only show one waveform. I can view the .fft file on PC and it contains all three waveforms.

Thank you. Both of these methods are very good. -Roman

Anyone tried to use parameters in pwl file? For example I compute time from .param fxy = 300/5000 and want to use that value in a pwl function of a voltage source. Example of entry: 0 0 {fxy} 1 It wor

Thanks for the idea. The utility lsputil is interpolating evenly spaced data if one does not exist. This is a cause of high degree of inaccuracy in spectra lines below 82 dB. We are looking at interpo

Hello, I need to analyze a circuit in frequency domain showing magnitude and phase (unwrapped). I have to use transient analysis because nonlinear effects are only modelled in time domain. Build in FF

Hello, I was trying to use the waveform part of the simulator. I don't understand why I get unexpected result with a sine wave. I use a result of a simulation running a simple circuit of a sine wave g

Hi Helmut, I see the solution and I like too. I would like to use this for other applications. I could not find any description on idt(x) function. Could you point to a right direction? Thank you, Rom

Yes, HSpice has it simple. I don't know LTspice that well yet. Maybe plotting results of DC sweep (Id vs. Vgs) and using the D() operator on the wave form would be the one way to go. Roman --- walterj

Yes, it can. Use DC op point analysis (.op) and then view Spice output file called Spice Error Log. Roman --- walterjsw <walterjsw@...> wrote: __________________________________ Celebrate Yahoo!

Hi everyone, With the new standard.bjt file we have to set KF=0 to assure correct noise computation. The fix is only good for noise spectra above 1/f knee. To analyze 1/f noise we need the correct val

Thank you. It works now. Roman --- Helmut Sennewald <helmutsennewald@...> wrote: __________________________________ Do you Yahoo!? Yahoo! Mail - 250MB free storage. Do more. Manage less. http://

How can I create a waveform derivative or integral? It would be very convenient in sweep analysis to find first or second derivative. In trans analysis integrating a waveform over unit of time can sho
