Hello John

"

Yes, SchBuilder offers you to choose your directory.
SchBuilder is installed in a private partition (not C:) and I try to save the built schematic in this partition.

Hi ,


Are you running it as administrator?


W10 is picky about such things.

Hello Helmut.
LTpowerCAD II design only
monolithic buck step-down regulators.
SwcadIII design step-down and step-up regulators.

Hello PhB

Bododynow talked about this version.


I expect that not all jigs-examples from today will run with this old version of LTspice.

Similar and enhanced functions are now available with the program LTPowerCAD II.
One has to enter input and output voltage and current. The program will then list parts. It also includes an analysis tool creating a Bode plot for example.


Best regards,
Helmut



LTpowerCAD II

The LTpowerCAD II design tool is a complete power supply design tool program that can significantly ease the tasks of power supply design with Linear Technology ?Module regulators and many other products, mostly monolithic buck step-down regulators. Unlike conventional simulation tools, this LTpowerCAD tool guides users throughout the whole supply design process: it searches suitable LTC parts according to user¡¯s supply specifications; then it guides the user to select and optimize circuit component values with suggestions and warnings. The tool shows real-time results of feedback loop bode plot, as well as the power stage performance. The design can be exported to LTspice simulation circuit for users to further verify their designs. The tool also provides PCB layout examples. Currently, this design tool works on Microsoft Windows based PC with Excel 2000, 2003, 2007, 2010 and 2013. With internet connection, the user can make real time update of the program and its component library. Contact LTpowerCAD@... for questions or support.

LTpowerPlanner

Included in the LTpowerCAD toolbox, there is also an LTpowerPlanner system architecture tool for system-level power management design and optimization.

It looks as though the program tries to save in a Windows protected location. Is there an option to set which folder to save to?

Hello Analogspiceman

Did you (or somebody else) try to run schbuilder;exe under W10?

When I run it , at the moment when I try to save the schematic I have apop windowwih:

" Unable to create file "
" Press OK to ignore and risk data corruption "
" Please cancel to kill the program "

I press OK but can't find the expected file anywhere.

I can see a trace of the file : a shortcut to the expected file in
%APPDATA%\Roaming\Micosoft\Windows

Re: PMBFJ620/2SK2145 or any other dual JFET-models exist for LTspice?

 

Thanks for this! :)


Re: ....list

 

But I am pretty much certain that neither Helmut nor Mike has written a
book about LTspice. So it is not surprising that nothing comes up written
by them.

Well, Mike did write the Help utility that comes with LTspice, and it has
been formatted into a PDF file from time to time, so I guess you could call
that a "book". But he has never "published" it for sale, and he doesn't
take personal credit as its author. It is just the Help that comes with
the program he created.
I think it's useful to add, once again, that Helmut is not affiliated,
in any way, with Linear, or Mike, nor is it this group, for that
matter.

Re: No XP?

 

Hello PhB.
The team was in SwcadIII menu. Activate this command was issued table (form) to enter the input voltage and load current. By entering the data you need and activated, you will get a table for the chip select. After selecting the chip, SWcadIII you create a scheme with all the values of the elements and start the simulation of the circuit. (The list of available chips of course not the same as now).
SWcadIII (as LTspiceIV) are portable Original Program. Those. there is no need to install.
I had a zip file. I unpacked it and ran
SWcadIII.

Re: No XP?

 

Hello Andy.
I am with you a little bit do not agree. Old SwcadIII had the opportunity to build the circuit on the input requirements for DC / DC. Recently, I studied my old files on CDs and found that version. For starters, the developers is a big help.

If you mean their ADIsimPE, I think you mostly don't need to use it.? So why bother, unless you have no other choice?

Many ADI parts have SPICE models.? SPICE models are SPICE models, and can be used in most any SPICE program, including LTspice, PSPICE, HSPICE, etc.

? ?"But similarly there does not seem to be older versions of LTspice than IV on LT's website?"

Why would you want an older version?? I can't think of any reason.

Sometimes, a company releases a program that is incompatible with older versions. ?(LTspiceIV -> LTspiceXVII is a minor example of that.? SwitcherCAD -> LTspiceIII -> LTspiceIV is not.) ?They keep the older versions because sometimes a customer needs the capability that only the older version has.

As far as I know, there is nothing that an older version of LTspice can do, that LTspiceIV can't.? So there is no reason to use an older version.

Ok I see that in the log. ?But I don¡¯t get prompted with any error for which I must ¡°press ok to continue¡­¡± which would lead me to look at the log in the first place.

Fine¡­ so (1) there¡¯s an error in the?2SC6144SG sub circuit from On Semi which raises log errors with respect to that sub circuit if all the Qd44vh10 pass transistors are replaced with?2SC6144SG. ?(2) If they are not, then LTspice tells me there¡¯s a missing Qd44vh10 model definition when indeed there isn¡¯t. ?(3) If all pass transistors are Qd44vh10 and the Spice directive in relation to the 2SC6144SG sub circuit is not ¡®commented out' in the schematic then LTspice tells me the model statement for Qd44vh10 is missing when it is not. (4) If all pass transistors are Qd44vh10 and the?2SC6144SG subcircuit statement is commented out of operation then all works just fine.?

For (1) the problem is in the log but with no ¡®flag' that the log should be checked. ?With (2) and (3) LTspice points me to a problem that doesn¡¯t exist and not to where the problem does exist.?

It took a lot of backtracking to identify that commenting out the?2SC6144SG sub circuit statement solved the problem. Of course then an examination of the material that needed to be commented out was readily done. It might well have been more obscure to identify had the?2SC6144SG sub circuit been one of many included via .inc statements. Better that LTspice actually alerts the user to the problem at hand rather than to an area which is just fine.?

Let¡¯s perhaps end this sidebar regarding the?2SC6144SG sub circuit here. The issue is now fixed / no longer needed. I still have outstanding questions with respect to probing phase for which I would be very grateful of assistance.?

Thanks in advance

Steve


EDIT: ?just saw John¡¯s post. ?The Qd44vh10 model is fine with respect to the device name / model name. ?The problem is with the 2SC816144SG sub circuit statement (with the .endl error noted by Philippe) and that LTspice points to an error with a missing Qd44vh10 model definition rather than an error with the 2SC816144SG sub circuit statement.?

Hello Jeff,

The attribute "value" in LM358Dual.asy has to be LM358DUAL and not LM358.

Unzip my example in a new folder and run it.
