Re: LTspice 24.1 Simulation Errors
That's exactly what happens. Nothing was changed.

Re: Weird results DC operating point for Tube amplifier
Well, I have not much to tell. The simulation worked right from day one, with 5.8V on the heater. However, just right now, running the simulation gave the same erroneous results as mentioned by many,

Re: LTspice 24.1 Simulation Errors
This was never the case. "VCC" is the required top level parameter in 74LVC1G, just as with 74HC and 74HCT etc.. If it is not set, LTspice (all versions) will set an error. If a top level parameter is

Re: Weird results DC operating point for Tube amplifier
Sorry, could you be more specific about your viable solution of .TRAN analysis (without UIC or Startup flag) ? I'm referring in particular to the ITS (aka DC operating point) solution (e.g. the DC

Re: LTspice 24.1 Simulation Errors
If you do this, could you ensure that all the changes are logged in the header of the library, so I can keep track of everything. Thanks. -- Regards, Tony

Re: Has anyone tried 24.1.3?
This has always worked. The keyword "WHEN" is always associated with the x-axis value. In .AC it is Hertz. In .TRAN it is time. "FIND <something>" should only really be used when <something> is

Re: Weird results DC operating point for Tube amplifier
I have no problem understanding the possible multiple equilibrium possibilities. My question was why does my installation succeeds everytime in finding a viable solution when it seems all others have

Re: Weird results DC operating point for Tube amplifier
This is not what "UIC" means or does. If you just want to start the DC sources at zero, use the "startup" switch instead. -- Regards, Tony

Re: Weird results DC operating point for Tube amplifier
The advantage of the 0V voltage source method is that it can easily be used in the argument of B-sources. -- Regards, Tony

Re: Understanding user file locations and structure.
It might not be the "right" word, but as you say, there might not be another that exactly describes the process. "Re-entrant" is another word that is used for similar things. OED:

Re: Weird results DC operating point for Tube amplifier
What do you really mean with "DC voltages look wrong" ? .TRAN 60 UIC skips the ITS step, hence there is not a DC solution at all. Do you actually mean the average of the voltages on some circuit's

Re: Monitor simulation percent completion from python
If you are simply using Python to call LTspice.exe in a batch process (with the -b switch), I don't know of a way to get thi

Re: Understanding user file locations and structure.
Thank you for the link to message 157669. I would like to see a focused step-by-step instruction on the process, using soft links as described by Tony, rather than hard links (which you do not

Re: Understanding user file locations and structure.
Thank you for the explanation. I don't think that 'recursive' is really the right word, because it means 'going backwards', whereas the desired action is 'going downwards' in the folder hierarchy. I'm

Re: Understanding user file locations and structure.
In this context, it means that it doesn't descend into sub-directories, and sub-sub-directories, etc.. If that is fixed in 24.1.*, that is good, but it won't change my practice, because I will

Re: Understanding user file locations and structure.
But it is, in 24.1. Adding this long desired functionality was a major piece of work. It isn't as simple as it appears at first. Best Regards, Mathias

Re: Understanding user file locations and structure.
Hello All: Message 157669 clearly explains the symbolic link method of setting up everything except the user.bjt, user.mos etc... files. I did my setup using hard links but you may succesfully

Re: Weird results DC operating point for Tube amplifier
Really? It looks pretty good to me.? What about it "doesn't look good at all" to you? Andy

Re: Understanding user file locations and structure.
It may well be better, but your instructions are too terse for me and many others. I think your third bullet is the way to do your second bullet, rather than a third discrete step, but I may be wrong.
