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

Tool for store Siemens S7 PLC's data, eg: DB, DI, M and more, in a local file, or write them from local file. Include data editor.

Software I/O Digital Analyzer and Digital Input/Output Simulator for electronics experiments. It's also a 16 digital channel data logger. Hardware supported: Ethernet I/O Card , USB I/O Card and Parallel Interface.

This project is aimed to develop an Hardware Monitor & Protection System for PCs using PICmicros. This project is divided into two branches: the first one involves microcontroller's firmware, the second one software used to manage the PIC via COM po
