ETAP vs LTspice

ETAP provides software and hardware for electrical systems across design, engineering, operations, and maintenance. Its modular energy management platform centers on a unified electrical digital twin for power system design, analysis, operations, and automation. ETAP 2026 includes analysis for renewable integration, feeder hosting capacity, Volt-VAR optimization, battery energy storage, and grid-code studies. Power Simulator is designed to predict system behavior, optimize grid performance, and run offline or real-time predictive simulations. DataX exchanges information across GIS, BIM, CAD, and legacy tools, with interfaces for products including Revit, AutoCAD, Excel, AVEVA, and ArcGIS. NetPM supports multi-user model creation, concurrent studies, change management, and role-based access. Grid Intelligence lists Modbus TCP, BACnet/IP, and REST protocols and integrations with systems such as SCADA, GIS, and OMS. ETAP serves utilities, infrastructure, industries, and buildings. Design and analysis products list supported 64-bit Windows systems; etapAPP is available for iOS, Windows, and Android tablets. Pricing is by customized quote, with a free 30-day demo and no free plan.

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.
