This project is destinated to develop um sistem to make more easy projects to embebed sistems that uses FPGA or Microcontrolers, and the programation in many plataforms and languages. There is a IDE and a hardware system to develop some products.
The idea of this project is automatize hydrogen Booster system created by Stanley Meyer to implement it in cars,trucks and electric plants as well as for production of free energy.
Register Interface Description tool
A tool to descibe sets of memory mapped registers and to generate different outputs, e.g. C header files, Verilog source code, HTML documets, from that description. This tool is written in Java and uses ANTLR for parsing and StringTemplates for output generation.
XFUNC 2.2 is a IBM PC program for DOS. It is an aid to Electronics Engineer who calculates transfer functions using symbolic algebra. It compute the frequency domain transfer function of a circuit in symbolic format, given a circuit description netlist in linear model. Calculate AC or DC symbolic transfer function in S-domain for Linear Circuits or Z-domain for Switching Circuits. Accept resistors, capacitors, inductors, dependent sources, ideal opamps, and ideal switches. Component values can be real numbers, symbols, or user defined symbolic expressions. Frequency domain results can be transformed to time domain via Inverse Laplace or Z Transform. Transformation between S-domain and Z-domain results can be done via Forward or Backward Derivatives (Euler Transform), Bilinear, or Impulse Invariant Transforms. Provide Bode, Gain-Phase, Nyquist, Pole-zero, Impulse, and Step response plots. Plot ranges can be set manually or automatically.
Simulation Tool for Phase-Locked Loops
A simulation tool for Phase-Locked Loops with charge pump phase detectors. The tool simulates phase and frequency steps with continous reference and random bit stream reference for data clock recovery.
upf2cpf is a cool command line tool which will takes in a UPF(Unified Power Format) and will convert it to a CPF(Common Power Format).This tool is very useful for Chip Design Engineers, who want to feed the power related info about the RTL in UPF/CPF.
5IO Keypad Library for Arduíno
After having some trouble configuring this little and useful Keypad for use with Arduíno, I have decided to create this library for using it easily. See the Wiki page for further details. If you install this library and find it useful, please remember to write a nice review, OK? Thank you! ;)
Gerber2eps - A small program for converting Gerber RS-274D files to Encapsulated Postscript (EPS).
Resinaut - a program and script for calculating parallel and serial resistor arrays and voltage dividers under availabilty constraints
A IC/MEMS layout editor. Features: all angle, font generator, macros, boolean operations, design rule checker, supported formats:Calma GDSII, OASIS (Open Artwork System Interchange Standard), OpenAccess, DXF, CIF (Caltech Intermediate Form), ...
Simcas is a simple and very flexible analog simulator. SimCAS uses symbolic equations to define components and solves the net system by using a "Computer Algebra System" algorithm.
Java Decision Diagrams (BDD) libraries: JDD and JBDD
This project used to contain two decision diagrams libraries: - JBDD: a Java interface to two popular BDD libraries, CUDD and BuDDy - JDD: a native Java library supporting BDD, Z-BDD Both projects have now been moved to bitbucket.org: - https://bitbucket.org/vahidi/jbdd/wiki/Home - https://bitbucket.org/vahidi/jdd/wiki/Home If you are wondering why the move was made after 14 years (!!) on SourceForge, I suggest you read this article: http://arstechnica.com/information-technology/2015/05/sourceforge-grabs-gimp-for-windows-account-wraps-installer-in-bundle-pushing-adware/
An active filter design assistant. Electrical engineers can use it to design and simulate analog active filters.
Boolean Function Optimizer using Quine–McCluskey algorithm
this project uses Quine–McCluskey algorithm to optimize boolean functions, the input function should be given in terms of minterm numbers and the output is optimized and in form of sum of products(SOP) there is also a Cost calculation and comparison between different optimizations.
These classes are useful for signal processing in Matlab or C++. They bring together tools and methods which may be used interchangeably for Matlab and C++. Their initial use is in conjunction with work towards my degree at UC Berkeley.
The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers, function generators, power supplies, GPIB interfaces, and more.
