ShortDescription: Powerful, fast, and free SPICE simulator software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits. Description: LTspice® is a powerful, fast, and free SPICE simulator software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits. Its graphical schematic capture interface allows you to probe schematics and produce simulation results, which can be explored further through the built-in waveform viewer. Moniker: ltspice ReleaseNotes: |- New Features 9/20/26 LTspice 26.1.1 MCP enhancements 8/3/26 LTspice 26.1.0 Add MCP server for use with third-party AI tools Bug fixes 5/6/26 LTspice 26.0.2 Automatically scale tiled subwindows when the main LTspice window is resized Performance improvement Add keyboard shortcuts for current source (I), Save As (Ctrl+Shift+S) and Close file (Ctrl+W) Warn if M suffix is used for frequency or resistance, or if F suffix is used for capacitance, in common GUI fields Enable FRA Bode-specific plot settings file load/save with default filename .fra_*.plt Make filename optional for .loadstate and .savestate directives If loadstate is specified without a filename, and no default file is found, sim starts from t=0 with a warning Warn if a schematic is opened from within a ZIP archive Remove "Directory for Temporary Files" field from Settings > Operation. - This was only used for temp installation files, etc. Raw file directory remains under Settings > Waveforms Add "Improving Convergence" document to Help > LTspice Help > F.A.Q. Bug fixes 12/1/2025 LTspice 26.0.1 Bug fixes 12/1/2025 LTspice 26.0.0 Parallel release on MacOS and Windows Add support for ARM processors Improved convergence Add support for loadstate/savestate/convreport defined as part of .tran analysis directive When editing a schematic, automatically start wiring if an unconnected pin is left-clicked Indicate default series resistance of 1mOhm when editing inductors on a schematic - Remove Settings > Hacks > Always default inductors to Rser=0 - To use default Rser=0 for all inductors, add ".options thev_induc=1" to the circuit Symbols autogenerated from .subckt's only include ModelFile base file name, not full path Add schematic menu action Hierarchy > Generate Subckt Netlist - Optionally use a symbol of the same name to define the subckt port order Add unicode support for file paths in GUI menus/dialogs stored in .ini settings file Improve display of recent files in File menu, show full path in status bar when hovered Add log warning for extreme value capacitors (>1kF) regarding default parallel resistance Change default value for waveform compression to disabled (Settings > Compression) Bug fixes 9/4/25 LTspice 24.1.10 Improved step legend behavior in waveform viewer Relaxed requirements for PWL files for independent sources - Automatically fall back to "PWL SCOPEDATA=..." behavior if the data is nonmonotonic. A warning is put in the log. Added a SCOPEDATA choice to the voltage/current source dialog. The file name can now be a string parameter. Behavioral source expressions using node voltages like "V(node)" can use a string parameter, e.g. "V({param})" Relaxed netlist syntax requirements - Syntax errors inside unused sub-circuit definitions in libraries are silently ignored if they are not instantiated MOS Model binning now silently ignored if only one model Added optional smoothed half-sine transition for pulse voltage sources Improved stepped trace behavior in waveform viewer Improved Nyquist for Loop waveform representation behavior Convergence optimizations Bug fixes 5/19/25 LTspice 24.1.9 .MEAS results saved into and SQLITE db file Bug fixes 4/29/25 LTspice 24.1.8 Bug fixes Unknown .model parameters are now silent warnings again instead of errors Attributes in schematic editor are only set to visible if they go from empty to populated (instead of any time they are changed) 4/10/25 LTspice 24.1.7 Bug fixes Nyquist for Loop representation added 3/25/25 LTspice 24.1.6 Bug fixes Enhanced table() function to load numbers from external file Enhanced .wave directive 3/09/25 LTspice 24.1.5 Bug fixes Node names can be expressions again, this time officially documented and supported /18/25 LTspice 24.1.4 Bug fixes and minor improvements 2/14/25 LTspice 24.1.3 Re-enabled expanded netlist functionality Bug fixes 2/1/25 LTspice 24.1.2 Re-enabled caret operator Duplicate .model cards are accepted if they are identical Duplicate .func, .param, and .subckt are accepted if they come from the same location in the same file Other bugs fixed 1/25/25 LTspice 24.1.1 Bug fixes 10/8/24 LTspice 24.1.0 Improved performance and convergence Add support for directory hierarchy for symbol search paths and schematic directory Add support for environment variables in Settings > Search Paths Add "All" symbol directories view in Place Component dialog Add .savestate and .loadstate simulator directives to save and restore the complete transient simulation condition Add ".option debugtran" to add report in log file to indicate convergence challenges Enhanced netlist syntax checking Introduced string parameters that allow easy stepping of models and subcircuits Allow device flags to be set to zero for ease of parameterization Changed default integration method to Trapezoidal Remember waveform compression settings (under Settings > Compression) between LTspice invocations Always accept "3k4" notation as 3.4k (no longer optional) Update FRA example fra_eg1 Update Help documentation Bug fixes 4/16/24 LTspice 24.0.12 Default location for plot settings changed to schematic directory (instead of raw output directory) Bring up Save As dialog when creating an auto-generated symbol from a netlist Fix rare waveform viewer crash Fix bug in schematic error misinterpreting simulation directives in certain situations Update FRA examples 4/5/24 LTspice 24.0.11 Fixed bug that caused problems with ascii data, plot settings, etc, in regions that use comma as decimal symbol Fixed bug that prevented automatic file extension concatenation in Save As function 3/21/24 LTspice 24.0.10 Fixed -encrypt option in command line Improved font clarity in schematic text editor dialog Bring up .step parameter editor when ".step temp ..." directive is right-clicked Allowed placing .OP data labels at any time Add working directory to top directory pull-down in Place Component dialog 2/2/24 LTspice 24.0.9 Fixed broken link in the new ADI web page 1/23/24 LTspice 24.0.8 Fixed a bug that caused noise analysis to get stuck if the schematic contained a syntax error 1/15/24 LTspice 24.0.7 Right-click on symbol brings up attribute editor if model has multiple subckt's, to provide model selector pull-down 1/12/24 LTspice 24.0.6 Fixed bug in pseudo-transient OP with .tran startup Renamed Step Legend as Annotate Steps and moved it's menu entry under ->Notes Annotations as well as Plot Settings->Notes Annotations Addressed high Ua values on the ISO16750 12V and 24V Load Dump Test A and B pulses 1/8/24 LTspice 24.0.5 Fixed a bug concerning controlled source with POLY(n) syntax using parameters Step Legend is now placed in plot rather than a modal window.
