LTspice vs ProfiCAD

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.

ProfiCAD is desktop software for creating electrical and electronic diagrams, schematics, control circuits, and technical diagrams such as pneumatic and hydraulic drawings. It can produce bills of materials, wire lists, terminal lists, and cable lists. The program includes more than 2,000 symbols and an editor for custom symbols. Drawing features include automatic symbol numbering and insertion, symbol search, and cross-references between wires and component symbols. Users can adapt or create ISO 7200 title blocks. The desktop program is for Windows; the maker says it can run on Mac using Parallels. ProfiCAD Viewer lets Android users view drawings, but it does not display cross-references. Drawings can be transferred to the viewer through cloud storage or email. ProfiCAD works offline, and drawings stay on the user's computer. It is not intended for PCB layout, 3D modeling, complex CAD, or full DWG/DXF editing. The free Home edition permits up to three pages, with commercial use limited to opening, viewing, and printing third-party documents. A full-feature trial lasts 30 days without a credit card; paid licenses start at $277, excluding tax.
