DIgSILENT PowerFactory vs LibrePCB

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.

LibrePCB is free, open-source electronic design automation software for drawing schematics and designing printed circuit boards. It runs as a desktop application on Linux, macOS, and Windows, and works fully offline without an online account. The schematic editor supports multi-page designs, live electrical rule checking, and automatic forward annotation to the board editor. Board tools include design-rule checking, a live 3D viewer, and multi-layer layouts with blind and buried vias. EAGLE projects and DXF files can be imported, while output jobs include Gerber, Excellon, CSV BOM, STEP, PDF, and SVG. An integrated library manager handles official libraries; users may also use their own. Projects and libraries use human-readable canonical text files, and projects carry their needed library items and settings. Users can order boards through LibrePCB Fab or export production data. GPLv3 licensing covers the source.
