Re: LTspice 24.1.4 Bugs
Oh...I would think they would fix that in this version The command works right, just looks weird.

Hi Andy No...it doesn't seem to matter. I also discovered if the statement is changed to a comment, the behavior is the same.

Re: LTspice 24.1.4 Bugs
Sorry, I misunderstood: That is not a new bug in 24.1.4.? The fact that the schematic editor displays it with the overbar, that is.? It has "always" worked that way, I think ever since LTspice had

Re: Issues running LTspice as a batch service
I tried putting all the symbols under the same folder as the simulation. Let me try to better describe what I am doing. A python service is polling an AWS message queue for incoming instructions to

Re: LTspice 24.1.4 Bugs
Does it work to put the filenames in quotes?? As a temporary workaround. I'm guessing it's a bug caused by changing the code for labeling nets/pins with the overbar, meaning "NOT". Analog Devices

LTspice 24.1.4 Bugs
If I add .inc/.lib statement on schematic: .inc file(3)_LT.txt It is converted to: .inc file(3)(overbar)LT.txt The "LT" characters get an overbar. Seems if a parenth, bracket, curly brace is preceded

Re: LTspice XVII error work around
#Time-step-too-small
I've never tried it with a switcher, but once I looked at the ripple voltage and current at the reservoir capacitor of a simple power supply, and saw what appeared to be a 'ghost' of the series

Re: LTspice XVII error work around
#Time-step-too-small
For resevoir and pump capacitors in switchers, I have found that adding ESR close to reality for the capacitor type, size and capacitance makes things better. I have also found that adding some

Re: LTspice XVII error work around
#Time-step-too-small
Let me see if I understand.? You have 3 5 or 6 ideal capacitors connected in parallel, which fails?? And when replaced by one ideal capacitor with the same total capacitance, it doesn't? I just want

Re: LTspice XVII error work around

You probably meant to say that you increased the tolerance values.? But you did that by making the magnitude of their negative exponents smaller, right?? So it's confusing to keep it straight, which

Re: LTspice XVII error work around

FYI, that is not unusual.? Combining models into the same simulation is often what causes misbehavior to rear its ugly head.? It's just how things often go. Another thing you might consider, is

Re: LTspice XVII error work around
#Time-step-too-small
Keep in mind, 5pF will be added to every single node in the circuit.? If you have an IC, which it appears you do (LT1375HV, maybe others), then it is added to every internal node of those models

Re: plot window
alan, I don't think you can add more than what LTspice gives you already in those plots.? There is no option to change the "Quantity Plotted" on the right axis, so no, you can't "hack" it to add

Re: .MEAS Failure
Indeed, it is troubling to wonder exactly what is meant by asking when a signal is "< 2V".? That happens continuously, after the signal crosses below 2.0 V.? Surely you would not want the .MEAS

Only for Bode. If you choose the Cartesian format, you can get imaginary. what other options do you want? S-parameters of 1 and 2 port networks are automatically available as plot options if you use

Right side of plot window is assigned to phase. Anyway to "hack" and assign right side of plot window to another parameter? Thanks.
