LTspice WS_SixPack example not working

TT_VT

I downloaded the example zip files, followed the instructions on the PDF to link the library paths, etc…, but "DPT_Test_Stand_SP" is not working.

Initially it gives error:

LTspice 24.1.0 for Windows

^^^^

I have made sure all the lib paths and such are included in the settings.

I add the ".lib WS_SixPack.lib" directive and it changes to the follow when I try to run:

(have tried .lib w/ WS_SixPack.lib without quotes w/ '…' and "…" to make sure it wasn't syntax, same result each time)

^^^^^^^^^^^^

I look in the lib file and there is only a single .subckt def for the module I am trying to use.

The Value parameter on symbol call is correct as well per the PDF.

Is there something I am doing wrong? Is the version of LTspice I am using not compatible?

Hello,

I've repeated the steps on my computer and was able to run the schematic.

You don't want to add the .lib statement in your schematic — the .lib include is defined in the symbol, so as the simulator has pointed out you now have duplicate definitions of the .SUBCKT statement.

For now, definitely update to the latest LTspice. There were some bugs with the 24.1.0 release of LTspice that have been fixed in the later versions. There's a good possibility that this issue relates to that version. If it doesn't, please provide me some screenshots/files so I can try to understand the issue better.

Thanks,

Brian
