a wine install takes a few minutes with packaged binaries or distro specific packages. it takes anywhere from 15min to an hour building from source code (installing wine itself). or LTSpice can be run on a VM with virtualbox running windows. i had some minor troubles with LTSpice running under wine a few years ago, but it was an error i made, but i found out in the process that LTSpice is built and tested to run under wine.

I'm running LTSpice under WINE. It is actually faster on WINE, for the number crunching at least. Simulation is faster, interface is slower. Strangely, I also found my old AMD computer ran LTSpice faster than my new Core 2 Duo (relatively new anyways...).

kees52,
You may try compatibility mode if Windows 7 is giving you trouble.

I have try that, than it hangs when I try to simulate, the whole computer has to be reset, I use 64 bit windows 7 maybe that is the reason.

regards and thanks.

have a nice weekend

Default PSPICE Calc V1.2 Triode Calculator

I thought I would share a free download program I wrote several years ago. It is a program that helps you optimize your triode models. There are no instructions with the download, but I will be glad to help with proper use of the program. There are screen-shots on the download page.

That looks nice. You may put the link in your signature and talk about it a few times in other threads just so it gets recognized by the community. Sounds like a tool I would like to have for BJTs and other transistors!

I'm looking for a bit of help with a Pspice .lib file from TI. It's an encrypted file and I get an error message of "Too few nodes:" then a long list of letters and numbers that is the first line after the ".subckt" text in the file. I think I built the asy correctly, numbering the nodes in the same order as shown in the ".subckt" line. Any thoughts or help would be appreciated. I've attached the .lib file with .txt appended.

Thanks

Ken

are you trying to use this with LTSpice? i don't think it will work. this may be a model for a particular version of Pspice that can make use of the $ENCRYPTED_LIB tag

Yes, LTSpice. Darn.

Rookie problem. Just getting the hang of LTSpice, after getting started in Simetrix.
I was able to put Bob's libs in successively by direct copy into the files, not a .include, but have not been able to figure out how to add the Exicon subcircuit models.

Here is the quickest way:

Add the subcircuit models as a simulator directive on the schematic. Then ctrl+right-click on the MOSFET symbol and edit the Prefix attribute to be capital X. Then write in the subcircuit name to be the Value attribute.

If you want to take the subcircuit text off the schematic, you can do two things:

1: right-click on the subcircuit text and select "invisible" from the menu. The text will reappear when the schematic is opened next.

2: copy the subcircuit into a .txt file and put it in the same directory as the schematic file. Use either a .inc or .lib directive on the schematic to import the .txt file. Now you can delete the subcircuit from the schematic as it will be redundant.

Hope this helps.
