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
JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs. With JMCAD, users can quickly develop software or "virtual" prototypes of systems or processes to demonstrate their behavior prior to building physical prototypes. The user builds his system model by selecting predefined blocks from a block library and simply wiring the blocks together. Each block of the diagram performs a function. Users can also create custom blocks in Java and add them to the JMCAD block library. JMCAD is a block diagram language for creating complex nonlinear dynamic systems.

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. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits. 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.

Eclipse-based IDE for design verification tasks
DVKit provides an Eclipse-based integrated development environment (IDE) for common design-verification tasks, such as developing SystemVerilog, C++, TCL, Python, and shell code
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).
FFT co-processor in Verilog based on the KISS FFT
bel_fft is a FFT co-processor that can calculate FFTs with arbitrary radix. It is a hardware implementation of the free software Kiss FFT ("Keep it simple, Stupid!"). The target was to allow a simple replacement of the software code with the hardware implementation. Therefore bel_fft comes with a software driver that is compatible with the Kiss FFT routines. bel_fft also has a modular architecture and allows interfacing different bus architectures. So far AMBA AXI, Altera's Avalon bus and the Wishbone bus are supported. However, bel_fft's architecture allows an easy adaptation to further bus architectures (e.g. AMBA AHB). It comes with a Java wizard to configure the co-processor and to generate all required files (e.g. twiddle ROMs). It comes with integration into Xilinx Vivado, EDK, and Altera QSYS and includes example designs for Xilinx Zynq and with PCI-Express core (including Linux driver and application). bel_fft is distributed under the GNU Lesser Public License 2.1.

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.
