Ngspice project aims to improve the spice3f5 circuit simulator.
Real Time Electronic Circuit Simulator.
Real Time Electronic Circuit Simulator. Include PIC, AVR and Arduino simulation. AVR simulation provide by simavr: https://github.com/buserror/simavr PIC simulation provided by GpSim: http://gpsim.sourceforge.net/
Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci
Import your PCB boards to FreeCAD
[ENG] Mod FreeCAD-PCB allow you to import PCB boards to FreeCAD. Scope of mod: - support for many different layers, - possible to choose colours, transparency and names for each layer, - mod allows you to import IGES models with colours, - possible to show holes/vias independent.

Możliwości modułu: - wsparcie dla wielu różnych warstw, - wyświetlanie otworów, przelotek niezależnie od siebie, - możliwość wyboru koloru, przeźroczystości oraz nazwy dla poszczególnych warstw, - importowanie modeli zapisanych w formacie IGS wraz z kolorami. ***** Supported software: - Eagle (*.brd) - Razen (*.rzp) - FreePCB (*.fpc) - gEDA (*.pcb) - FidoCadJ (*.fcd) - KiCad (*.kicad_pcb) - IDF v2/v3 Requirements: FreeCAD >= 0.14 Project forum: https://sourceforge.net/p/eaglepcb2freecad/forum/
gpsim is an open sourced simulator for Microchip's PIC microcontrollers. It supports all three families of PICs: 12-bit, 14-bit, and 16-bit cores. See also gputils http://gputils.sourceforge.net/
The project development has been moved on GitHub https://github.com/pcb2gcode/pcb2gcode The GUI for pcb2gcode can be found here https://github.com/pcb2gcode/pcb2gcodeGUI pcb2gcode is a command-line tool for isolation, routing and drilling of PCBs that provides full support for both single- and double-sided boards. For more information, see http://sourceforge.net/apps/mediawiki/pcb2gcode/
The Boolean Expression Reducer provides the user with various tools to visualize and analyze boolean expressions. Given an expression, it also reduces it to its Sum of Products and Product of Sums form.
PVSim is a Portable Verilog Simulator for Mac OSX, Linux, and Windows. It features a fast compile-simulate-display cycle. The core is in C++, and the GUI, wxPython.
xc3sprog is a suite of utilities for programming Xilinx FPGAs, CPLDs, and EEPROMs with the Xilinx Parallel Cable and other JTAG adapters under linux. Originally based on code written by Andrew Rogers (http://www.rogerstech.co.uk/ ).
AVR simulator IDE
Electronic circuit simulator. Simple environment to run and debug firmware for AVR 8-bit microprocessors. Able to run arduino firmware. Internally this program uses the open source Simavr AVR Processor Simulator (https://github.com/buserror/simavr) and wraps all its functions in a GUI shell. Setups for firmware debugging scenarios can be created dynamically. Able to run 16MHz MCU with decent set of external parts in real time. In particular this can be used for development of CNC firmware in conjuction with its CAM frontend without access to the real hardware. For Linux and Windows systems. Please visit wiki pages (https://sourceforge.net/p/simutron/wiki/Home/) for instructions
A collection of useful software packages to perform engineering tasks, especially electrical engineering and chip design. All packages come as shrink-wrapped installers for Apple's Mac OS X.
Qt based Veroboard, Perfboard, and PCB layout and routing application
Cross-platform software for producing Veroboard (stripboard), Perfboard, and single-sided PCB layouts. Automatically prevents short circuits and checks for open circuits. Interactive auto-routing. Can produce PDF output for toner transfer. In-built tutorial. Built using the Qt cross platform library, and tested on 32-bit Linux, and on Windows 7 (32-bit and 64-bit). Precompiled versions available for Windows.
Visually build and simulate boolean logic circuits
Visually build boolean logic circuits and then simulate their operation. Create custom components from user-designed circuits. Written in Java for cross-platform functionality. NOTE: This project has moved to Bitbucket at http://bitbucket.org/kwellwood/circuitsandbox
Wcalc is a tool for the analysis and synthesis of electronic components. Some of the models include coupled microstrip lines, single layer air core solenoid inductors, etc. Wcalc can analyze the electrical parameters based on the physical dimensions a
PEP is a modelling and verification framework for parallel systems, providing a large number of different modelling languages and verification techniques (e.g. SDL, Petri nets and model checking)
SDBoot is a complete bootloader solution (MCU side and PC side), free, with source code for AVR MCU chip. It features a checksumed protocol for safe programming.
Parallel Port Eprom Programmer contains a GNU/Linux driver that controls the eprom programmer throught the parallel port and a tool which allows reading and writing eproms.
ShortCut is a printed circuit board (PCB) design software. It is intended for people who develop small electronic devices and do not want to be annoyed by the PCB design process. ShortCut has some advanced functionalities.
