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
kicad StepUp allows exporting kicad 3D board and comps in STEP AP214
kicad StepUp: a new approach to export kicad board and modules in STEP AP214 (with colors). With kicad StepUp, it is possible to work in kicad EDA with the same component model data available in the STEP AP214 3D format, and obtain a 3D STEP AP214 model of the pcb board and a complete board assembles with electronic modules, to be used for MCAD interchange. The accurate 3D visualization of components on board assembles in kicad 3dviewer, is maintained in the same accuracy and aspect in STEP AP214 format. The kicad StepUp script maintains the usual way to work with kicad, but improves the process to work in a collaborative way with mechanical designers bringing near ECAD and MCAD environments.

Digital Circuits Design and Simulation
Digital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. In this software, circuit can easily be converted into a reusable Module. A Module may be used to built more complex circuits like CPU. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display and Digital Oscilloscope etc. provided in the software. This Software may be used by professionals, hobbyists and students alike. The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems. In this software, a circuit may be designed using graphical components or may be entered as Sum-of-Product Boolean form.

Integrated Development Environment (IDE) for learning HDL
UMHDL is an educational Integrated Development Environment (IDE) intended for learning digital designing with programmable logic devices using Hardware Description Languages (HDL) through simulation. It is an open-source application created at the Miguel Hernández University (UMH). The aim for the UMHDL development was to have a graphical application that allows learning the VHDL language without licensing restrictions (using some existing open-source tools) and requiring few resources. So, the interface developed acts as a front-end that allows writing code (with syntax highlighting), invokes an external VHDL compiler and simulator (such as GHDL), and displays the result of the simulation graphically as waveforms (invoking to GTKWave).
Yet Another JNI-D2XX Interface Project
A Java Native Interface (JNI) library suitable for communicating with a range of USB interface chips from FTDI via the D2XX driver. It currently supports OS X 10.10+ and Windows 7/8 x64. On OS X, the 64 bit JVM is supported. On Windows, support is limited to the 64 bit JVM (Java 1.8 is now 64 bit). Version 1.0 (In progress) --------------------------------- - Java 8 - SPI support and sample (via MPSSE)
JQM - Java Quine McCluskey for minimization of Boolean functions.
Java Quine McCluskey implements the Quine McCluskey algorithm with Petrick’s Method (or the method of prime implicants) for minimization of Boolean functions. This software can be used both for learning and solving real problems. As learning/teaching tool it presents not only the results, but also how the problem was solved as well as how to use Karnaugh Maps to solve the problem. Up to sixteen functions of sixteen variables can be minimized. A graphical interface is provided for entering and editing the truth table that can be saved and loaded. The results can be exported in HTML format. It generates the Karnaugh Map for educational purpose and the actual truth table from the obtained expressions even when multiple solutions for each function are found. This implementation supports PLC programming, so results can be presented in many forms including Structured Text (ST) and Ladder Diagram (LD) along conventional Boolean expression.
This is a simple viewer for the ``Stream Format'' for CALMA GDSII CAD libraries (``GDS II'', ``.gds'' or ``.sf'') with a couple of limitations. The main functionality is viewing the library layers with different colors.
