LTspice vs SOLIDWORKS

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.

SOLIDWORKS provides 3D software for creating, simulating, publishing, and managing product data. SOLIDWORKS Design supports parts, assemblies, drawings, sheet-metal, and framing workflows; the portfolio also includes simulation tools for evaluating performance, efficiency, and durability. The installed Design application can work offline. With Cloud Services, it connects to the 3DEXPERIENCE platform for collaboration and data management, including sharing and marking up designs and managing revisions. Browser-based xDesign tools provide modeling without a local installation. Standard with Cloud Services costs $2,820 a year for a single machine-locked device, excluding local taxes. Professional costs $3,456 a year and Premium costs $4,716 a year, each for a single user and excluding local taxes. A Makers plan costs $48 a year for personal, non-commercial use, and Design Standard is free for students. The listed platforms include macOS, web, and Windows, though client SOLIDWORKS products list Windows 10 and Windows 11 64-bit support; eDrawings for Mac lists supported macOS releases. Online purchases include support, and orders can be canceled and refunded within 15 days.
