Open Source Java Electronic Design Automation (EDA) Software

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

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.

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

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.

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.

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.

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

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.

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 --------------------------------- - Java 8 - SPI support and sample (via MPSSE)

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.

Pipes is a desktop system which analyzes an AutoCad(TM) drawing of a sprinkler system, checks for flaws and after these are eliminated, adds the size/diameter labels to the drawing.

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.

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

A Java API for manipulation of GDSII stream data. It is intended to provide a useful, reusable and platform independant library for CAD/CAE application developers. This API Requires the Java Backus-Naur Test API (JBNT). You may download it from: ht

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.

This is a very powerful Schematic and PCB layout tool for electronic Engineer. It is very easy to use. Coming version will add the SPICE features as well as the 3D model. This tool is target for single user, so all the things such as Schematic, PCB layout, SPICE model, 3D models are all combined into a single project file "*.prj" in ZIP file format. Anyone should able to explore and see the structure of files using any zip tool.

This program provides for easy modification and viewing of SPICE circuit files. It will also read SPICE3 RAW format (as well as GnuCap) and create graphs of results through an interactive GUI. It supports waveform math, copying to clipboard, and saving.

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.

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.

Netsim is a mobile ad hoc network simulator targeted at large heterogeneous node configurations. It is written in Java and is easily extensible through its modular concept.
