TTA-based Co-design Environment (TCE) is a toolset that provides a complete co-design flow from C programs down to synthesizable VHDL and parallel program binaries. Processor customization points include the register files, function units, supported operations, and the interconnection network.
Alliance CAD System is a set of EDA tools and portable cell libraries for VLSI design. It covers a wide range of the standard design flow (from VHDL up to layout). It includes a VHDL simulator, RTL synthesis tools, place and route tools, netlist extractor, DRC, and a layout editor.
XCircuit is a UNIX/X11 program for drawing publishable-quality electrical circuit schematic diagrams and related figures, and producing circuit netlists through schematic capture. XCircuit regards circuits as inherently hierarchical, and writes both hierarchical PostScript output and hierarchical SPICE netlists. Circuit components are saved in and retrieved from libraries which are fully editable. XCircuit does not separate artistic expression from circuit drawing; it maintains flexiblity in style without compromising the power of schematic capture.
The Eagle EDA software is composed of tightly integrated modules for PCB design, including Schematic Capture, Board Layout, and Autorouter. There is a free full-function (only board size limited) non-commercial license available for hobby and educational use as well. Windows, DOS, and of course, Linux versions are available.
Platform Independent Petri Net Editor (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively. A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations. Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification. PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.
Easy Funktion is 2D function plotter software with an equation solver. It has an office-like GUI frontend and features a built-in pocket calculator, calculating with complex numbers (with special extensions for electronics, e.g. capacitor/inductor impedance), a function to export to spreadsheet software, and an advanced formula editor with automatic formatting.
