Circuitmod is a circuit simulator that extend the capacity of the original Falstad's Java Circuit Simulator into CMOS Chips, Led Arrays, Led Matrix and PIC Programming. The Horizon is limitless. Try today.

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.

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.

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.

Java Quine McCluskey (JQM) implements the Quine-McCluskey algorithm with Petrick’s Method for minimizing Boolean functions. Designed for both education and industrial application, it handles up to 16 variables and functions. Uniquely, JQM bridges the gap between theory and practice: it visualizes the solution process with generated Karnaugh Maps for students, while supporting PLC engineers by exporting results to Structured Text (ST) and Ladder Diagram (LD). The software includes a GUI for managing truth tables and supports diverse file formats for import and export.

Modelio-Open is a project hosting a set of open source extensions (SoaML, SysML and UML Testing Profile) for a previous version (1.2) of the Modelio Free tool . Currently, the lastest version (2.x) of Modelio modeling and generation tool is available at http://modelio.org/downloads/download-modelio.html. All extensions are downloadable at http://forge.modelio.org/projects.

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.

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.

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. Tutorial: http://users.norwoodlight.com/janh/wink/autopipes-entry.htm

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.

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.

ElectroMimic is an electronic circuit simulator in Java™. The simulator is focused on the piecewise-linear models normally used by undergraduate students, but can also be linked with external simulation software for more realistic results.
