In their own words
CircuitLab
CircuitLab provides in-browser tools for schematic capture and circuit simulation for students, hobbyists, and professional engineers. It supports analog, digital, and mixed-mode simulation, plus frequency-domain analysis and parameter sweeps. Users can import SPICE device models and use CSV files as signal sources. Schematics can be exported as PDF, PNG, EPS, or SVG, and unique circuit URLs make it possible to share designs or ask for help.
CircuitLab runs on Windows, Mac OS X, and Linux and works in a browser on iPad. Its membership information also describes offline access through the Chrome Web Store and SSL-encrypted access. It offers a free plan and paid subscriptions, including Micro at $24 a year, Hacker Lite at $16 a month, Hacker at $26 a month, and Pro at $39 a month. The pricing note lists a starting rate of $2/mo (annual). Commercial use is permitted with Pro and Enterprise subscriptions; otherwise, the terms describe use as personal and non-commercial unless otherwise specified. Support includes online documentation and community forums.
DIgSILENT PowerFactory
DIgSILENT PowerFactory is software for analyzing electrical generation, transmission, distribution and industrial power systems. Its study areas include renewable integration, distributed generation, and medium- and low-voltage networks. Available analyses cover load flow, short circuits, contingencies, protection, stability and electromagnetic transients. Users can automate work with Python, DIgSILENT Programming Language, a C++ API or a parallel task automation tool. The base package imports and converts network data; its DGS interface exchanges data in ASCII, XML, CSV and ODBC formats for GIS and SCADA connections. Additional interfaces include OPC DA/UA, IEEE C37.118 simulation and FMI 2.0 co-simulation, though some require separate licences. Editions range from a local SQLite setup to licence-server management and shared project data using Oracle, SQL Server or PostgreSQL. The 28-day demo is free for one user, with predefined functions, and excludes DGS, exports and API. Commercial pricing is available on request; platforms listed are Windows, API and self-hosted.
