Do you have a Linux version of this program?
No. But there are reports that LTspice XVII does run on Linux under WINE.
OK, I've never used WINE, how do I install this?
Check with http://www.winehq.com to find the current version of WINE for your system.
Copy the appropriate .rpm file to your machine and open it from nautilus.
Get the file LTspiceXVII.exe from http://www.linear.com. In an xterm, execute "wine LTspiceXVII.exe" to install LTspice.
There will now be a Linear Technology Logo on your desktop. Double click it to start or type "wine LTspiceXVII.exe" from an xterm to start the program.
The schematic fonts don't scale as smoothly under WINE as Windows. Why is that?
WINE is doing the best it can with the fonts it finds. It will do better if you tell it how to find the font files from your Windows system.
The PWL additional point editor doesn't look right under WINE?
Try using the native Windows .dll from your licensed Windows system. The command line to then invoke LTspice from WINE is wine -dll commctrl,comctl32=n XVIIx64.exe.
How does the performance running under Linux compare to running under Windows?
Every Linux user you ask will tell you that LTspice runs better under Linux than Windows.
Wow, cool! Does it really?
No.
