Open Source Windows Electronic Design Automation (EDA) Software

Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.

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

The DigitalSimulator is your Virtual Electronics Lab, allowing you to design, simulate and output your digital circuit board designs.

A graphical tool for designing finite state machines and exporting them to Hardware Description Languages, such as VHDL, AHDL, Verilog, or Ragel/SMC files for C, C++, Objective-C, Java, Python, PHP, Perl, Lua code generation.

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers, function generators, power supplies, GPIB interfaces, and more.

If you ever worked with the MC34063 Switching Controller, you know what a pain it is to calculate all the part values. This tool is an universal tool to help you with this process. You can calculate any standard application, such as step-up, step-down, inverting and step-up-down. PS: I would be happy about any (positive xD) reviews as well as any bugreports, comments or feature requests that you might have!

Gerber2eps - A small program for converting Gerber RS-274D files to Encapsulated Postscript (EPS).

Digital circuit simulator with an own IC-scripting-language, programmed in Visual C++ 2003.net, currently only available for Windows. Major technical goals: Creation of a bugfree interface and effective signal simulation. All config-files in txt-format.

Still struggling with Excel to setup your pick and place machine ? Cad2Board reads component mounting information from Eagle, Altium Designer and Mentor Expedition PCB designs. Component or component groups can be assigned to feeder slots by drag and drop. Any modifications for PCB population can be defined to generate PCB variants, consider rotations from unusual tape and reel packaging or to account in advance for CAD library or PCB design bugs. Generated setup data is stored in a seperate project file. Succeeding PCB revisions what contain redesign changes can be merged with existing project setup data. Inconsistencies are highlighted to solve them by new assignements and unused feeders can be cleaned up with a single push. Finally a machine program is generated in Heeb HE50 format and downloaded to the machine interface.

"DSO" is a Digital Signal Oscilloscope. My DSO will be connected via the USB to the PC. All software to operate the DSO is developed within this project.

A IC/MEMS layout editor. Features: all angle, font generator, macros, boolean operations, design rule checker, supported formats:Calma GDSII, OASIS (Open Artwork System Interchange Standard), OpenAccess, DXF, CIF (Caltech Intermediate Form), ...

Open firmware for Honeywell Rondostat HR20 radiator thermostats

OpenCADServices is an interface standard for Mechanical Computer Aided Design (CAD) systems that enables the interoperability of CAD, Computer Aided Manufacturing (CAM) and Computer Aided Engineering (CAE) tools. (OMG CadServices)

PCB-Tools is a system independent, a Java programmed Eclipse-RCP application for developing circuit diagrams and printed circuit boards. It uses Eclipse Graphical Editor Framework (GEF) to draw diagrams and layouts.

PikLoops is a simple KDE program used to generate assembly time delays for Microchip microcontrolers using Microchip instructions.

toolbox with information and programs for Computer Aided Innovation The scientific background of Skidbladnir is known as the Theory of Inventive Problem Solving; in English abbreviated as TIPS or TRIZ, in German as TRIS.

Simulator for thermal conduction in solid material. Uses SPICE for calculations and wxWindows for providing Windows and Linux GUI.

esweep is a scriptable audio measurement program which features various signals and signal processing functions. Its main purpose is the measurement of speakers.

WARNING: This project is under hard development and not intended for productive use yet but only for discussion. jCLS helps to create and maintain fine detailed component libraries for EDA tools like Altium Designer. It provides tools for data generation for masses of single parts from only the most necessary informations. Having good maintained and rich described and voluptuous detailed component libraries needs normally masses of time, work and discipline. jCLS comes here to save you from the molesting parts of this job. Feature in progress: -Some graphical improvements -Conceptual improvements -Some improvements in the file format Features added in next Release: -Built-in tutorial -Better libraries with library browser -Save and load libraries from a file -Export library data to csv files -Automatic Update Notification

tkCybernetics is a small grafical tool for rapidly setting up simulations of simple cybernetic systems. It was designed for didactic purpose but might be useful for the quick test of some circuit too.

Virtual electronic circuit simulation with JAVA based schematic entry and wave viewer, based on (Berkeley) SPICE, for any OS/Server/Browser configuration. Due to missing public feedback for over one year its status is set to INACTIVE (1/2004) - sorry.
