LabVIEW vs LTspice

LabVIEW is a graphical programming environment for developing automated test and measurement applications. Its G language uses dataflow programming, supports parallel execution, and includes interactive debugging. LabVIEW connects to instruments from any vendor and offers more than 7,000 instrument drivers. Engineering analysis functions and a native interface support monitoring and controlling tests. Editions can integrate Python, C/C++,.NET, and MathWorks MATLAB code. The Professional edition includes Application Builder, NI Nigel AI, software engineering tools, and Report Generation, Database Connectivity, and Advanced Signal Processing Toolkits. The Community Edition costs nothing, but is limited to personal, non-commercial, non-industrial use and cannot be used for teaching or research at a degree-granting institution. Professional trials provide seven days of access; the downloadable trial can be extended up to 45 days after first opening it. The downloadable trial connects to physical hardware, while the web trial uses simulated hardware only. NI lists Windows and Linux support for editions; starting with LabVIEW 2025 Q3, Community Edition is the only macOS edition. Each target computer running a developed application requires a perpetual deployment license.

LTspice is a SPICE simulator, schematic capture tool and waveform viewer for analog circuit simulation. Its graphical schematic interface lets users probe a design, run simulations and inspect results in the built-in viewer. The download includes macromodels for most Analog Devices switching regulators and amplifiers, as well as a device library for general circuit simulation. Users can import third-party SPICE models implemented with .MODEL directives or .SUBCKT blocks. Designs from Signal Chain Designer, Analog Filter Wizard, Analog Photodiode Wizard, Precision ADC Driver Tool and LTpowerCAD can be exported to LTspice for simulation or verification. Tutorials address schematic creation, transient and AC simulation, waveform viewing, transformers, third-party models and noise analysis. The EngineerZone forum is available for questions and discussion. Analog Devices presents LTspice as an engineering design tool, with demo circuits and model libraries for designers. It is listed for Linux, macOS and Windows; the free plan specifies Windows and macOS downloads. A verified forum answer from an Analog Devices employee says telemetry is sent only if users opt in, and that the setting can be changed.
