The SESAME (Simulation of Embedded System Architectures for Multilevel Exploration) software system is an embedded system co-simulation environment and research tool which implements the ideas of the SESAME project at the University of Amsterdam.

Tool-independent Makefile generator for VHDL models.

VTracer is a Verilog Testbench developer aid. Contains well documented Verilog-Perl co-simulation environment (TCP sockets based), structural Verilog parser, demo Testbenches.

A Hardware/Software Co-Simulation package utilizing TCP/IP networking to allow C and Perl based development simulation environments using Verilog or SystemC hardware models.

VSTGL is a graphical editor for Signal Transition Graphs (STG) and Petri nets. VSTGL is able to export the created STG to Petrify - an advanced tool for analyzing and optimizing STG's - or run Petrify on the graph directly.

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.

A portable loudspeaker design system supporting measurement, modeling, simulation and optimization of boxes, filters and systems.

asfpga is an assembler written for use in FPGA design. It can be easily modified for your instruction set. The ultimate goal of this software is to allow a FPGA designer to easily write assembly code for a custom instruction set. The current version al

Brushless DC controller (ESC) Fully functional sensorless ESC. Uses BEMF detecton for rotor position sensing. Software trays to maintain maximum speed on currently available power(pwm duty). It works like ordinary DC motor. More load means, on same power, lower speed and higer current. Motor speed (current) PWM , direction etc. is adjustable via serial port commands. For example - press "k" button to add power, "j" button to reduce power and "t" button to reverse rotor direction etc. I have used neodymium magnets BLDC, CD drive BLDC and car generator as BLDC motor without any modification in software, hardware - it just works. Schematic is done using EAGLE PCB software Software is witten in spin langue. If You want to improve this project then put your thoughts into discussion section. Or if You have some burning information - drop me an email "htamme@ut.ee" enjoy,

decida is [de]vice & [ci]rcuit [d]ata [a]nalysis. It is used for electron device characterization, procedural simulation/analysis of electronic circuits, or more general data analysis tasks.

IMPORTANT: The flosslogic project has merged with the sigrok project. Development continues in the sigrok wiki, mailing lists, IRC channel, and git repository.

mcuStudio is a development environment for Microcontrollers. It's based on Eclipse (plugin). The aim is to provide a high quality development environment for electronics. First editions will target Microchip Pic mcu's. Other mcu will be supported later.

"mprfgen" is a multi-port memory generator that can be used for VHDL designs. It can generate either generic or Xilinx-specific (through component instantiation) multi-port memories.

An assembler for the Xilinx Picoblaze soft processor.

A simple VHDL(VHSIC Hardware Description Language) preprocessor

YAPI (Y-chart Application Programmers' Interface aka Yet Another Programmers' Interface) is a C++ library for writing (Kahn) Process Networks.

wxArt2D gives wxWindows applications sophisticated vector drawing functionality. It is based on a framework supporting multiple views within a hierarchical document. Supports drawing & (Graph) editing. In-output in SVG, GDSII, XML, easy to extend.
