Lepton EDA is a suite of software tools for designing electronics. It provides schematic capture, netlisting into over 30 netlist formats, and many other features. It was forked from the gEDA/gaf suite in late 2016 by most of its active developers at that time.
The GPL Electronic Design Automation (gEDA) project has produced and continues working on a full GPL’d suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting, analog and digital simulation, and printed circuit board (PCB) layout.
This is free and open source software.
Key Features
- liblepton – a library of functions for manipulating Lepton schematics and symbols and rendering primitives.
- libleptongui – a library of GUI functions.
- lepton-schematic – a schematic editor.
- lepton-attrib – a spreadsheet-like program for bulk editing of component attributes.
- lepton-netlist – a highly-flexible, hierarchy-aware utility which parses schematics to generate a number of outputs, including netlists for a wide variety of PCB layout tools. It can also generate bills of materials and DRC reports for your schematics.
- lepton-sch2pcb – a command-line utility for streamlining the workflow where ‘PCB’ http://pcb.geda-project.org/ and lepton-schematic are used together.
- lepton-symcheck – a utility for checking for common errors in schematic symbol files.
- lepton-cli – a utility for interactive and batch mode working with Lepton EDA Scheme API, exporting schematics into various formats, and configuring all the programs of the suite.
