Operation

Settings marked with an asterisk [*] are remembered between program invocations.

Default Window Tile Pattern: Allows you to set a preference for windows tiled side by side instead of one above the other.

Marching Waveforms: Check to enable simulation results to be incrementally plotted during the simulation.

Generate Expanded Listing: Dump the flat netlist after expanding subcircuits to the SPICE Error Log file.

Save all open files on start of simulation: LTspice simulates the schematic in memory, not the one on the disk. This option forces the two to be in sync at the start of every simulation.

Automatically delete .raw files: This allows waveform data files to be deleted automatically after closing a simulation. This dramatically reduces the amount of disk space used by LTspice but requires the simulation to be rerun when you reopen the simulation.

Background image: Select the background of the main application window frame. The default is a stipple pattern so that that background isn't confused with a blank schematic. Other choices include a da Vinci drawing of a collection of his inventions or a user-supplied jpep file that needs to be stored at path location %USERPROFILE%\LTspiceXVII.jpg

RAM for Fast Access Conversion: This allows you to tune memory usage when you convert waveform data to fastaccess files format.

Directory for Temporary Files: Directory for temporary storage of update files downloaded during a Sync Release.
