DLD V 2.0 Released 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. You may start your circuit from simple gates and flipflops and keep on converting them into ICs. These ICs, later on, may be incorporated into other circuits to built more complex circuits like CPU. You may even use SOP expressions to generate digital circuits in IC form. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display as well as CRT and digital Oscilloscope all 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.

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.

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.

Eclipse Verilog editor is a plugin for the Eclipse IDE. It provides Verilog(IEEE-1364) and VHDL language specific code viewer, contents outline, code assist etc. It helps coding and debugging in hardware development based on Verilog or VHDL.

ImageToGerber makes it easy to convert any image to gerber files, ready to send to a PCB manufacturer. More info at: https://www.imagetopcb.com Demo video: https://youtu.be/HUvt0mOHv_M Forget about spending long hours etching and drilling at home, or learning to use complicated CAD software, schematics, layout design,… And more importantly, ImageToPCB is more than just a converter, it expands the potential of your design or image. It unlocks the possibility to easily make improvements and updating your design, as you will be able to make design modifications, add a silkscreen layer, resize drill diameters, create a soldermask layer to protect copper areas and to avoid accidental shorts, convert a single-side design into a double-side or multi-layer design,… all that just by editing your image with your preferred image editor.

SVEditor is an Eclipse-based IDE (Integrated Development Environment) for SystemVerilog and Verilog files. It features syntax coloring, content assist, source indent and auto-indent, and structure display.

DVKit provides an Eclipse-based integrated development environment (IDE) for common design-verification tasks, such as developing SystemVerilog, C++, TCL, Python, and shell code

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

Signs is a development environment for hardware designs in VHDL and other hardware description languages. It provides synthesis and simulation tools which are fully integrated in an Eclipse plugin including graphical netlist and waveform viewers.

HDLObf is intended to be a HDL Obfuscator and identifier name change utility. Primarily designed for Verilog/SystemVerilog support will be added for VHDL/SystemC in future.

PIC Development Studio is a simulator for the PIC16F84 microcontroller. It also provides a plugin framework making it possible to develop custom components. A library of ready-made components is included.

Ycad is a library of CAD functions in Java. Currently only DXF is supported for reading, viewing and writing. The DXF drawing may be rendered to a Graphics object for printing or imaging.

This project provides a analog / mixed signal IC schematic capture and layout tool with the accompanying netlisters, simulators, and verification tools.

Given a simple net-list describing the high level power architecture of your system Penthode: - simulates the voltage and current from device turn on to the steady state. - highlights components working out of specification - draws a nice power tree diagram showing the currents/powers balance - plots node transient voltage and gate current waveforms It is possible to change component parameters interactively to improve the design

PCB Layout and Schematic capture tool for Win/Linux/Mac. Source code at https://github.com/sergei-iliev/myNetPCB

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.

JSDAI is a toolkit for STEP (ISO 10303), the STandard for the Exchange of Product Model data, that enables linking of CAD, CAM, PDM, PLM, CAx systems. JSDAI supports the development of Express data models (ISO 10303-11) and their implementation in Java.

The aim of this project is to develop a GDSII viewer by using Java programming language. Efforts will be made especially on ease-of-use, efficiency, and capacity.

TimeDoctor is a tool to visualize execution traces of tasks, queues, cache behavior, etc. While originally targeting embedded media processors and includes specific features for analyzing audio/video streaming applications it has wider applicability.

zamiaCAD is a modular and extensible platform for HW design, analysis, and research. It translates a HW description (VHDL or Verilog) into a language independent IG structure. Applications like a simulator and an eclipse GUI build on top of the IG.

An API for manipulating EDIF netlists in Java. We use this API to analyze netlists as a part of our FPGA reliability project. We intend to keep the API as general as possible to support other netlist analysis and manipulation activities. This material is based upon work supported by the National Science Foundation under Grant No. 0801876. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.

CircuitSmith is to be a comprehensive electronic design package being developed in Java which will include schematic capture, printed circuit board layout and any other features which I (and hopefully others) can be bothered to program.
