A circuit simulator with graphical user interface (GUI)
Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.
GHDL - a VHDL simulator
GHDL is the leading open source VHDL simulator. *** Now on github.com/tgingold/ghdl *** We have binary distributions for Debian Linux, Mac OSX and Windows. On other systems, getting GHDL from here means downloading the current source package and building GHDL from source. Alternatively you can get the latest source version (warning : occasionally unstable!) by pulling a snapshot from the git repository.
This project provides a analog / mixed mode IC grade schematic capture tool with the accompanying netlisters.
An HDL alternative to PCB graphical schematic capture tools.
PHDL is an HDL that functions as an alternative to mainstream graphical schematic capture tools. The language is compiled into a pcb netlist which can then be imported into a layout tool. We are currently on version 2.1 of the tool. We have created an eclipse plugin version of the tool as well as a standalone command-line based version. Both function identically and output a netlist that can be imported into a pcb layout tool. VHDL revolutionized how FPGA designs and digital logic circuits have been designed and captured and overcame many of the difficulties associated with the use of schematic editing tools. We believe the use of an HDL is also the way of the future when it comes to PCB design. The PHDL compiler automatically supports the output of PADS and Eagle netlists, and through extending a simple java class, users can generate a netlist in practically any format required by their choice of a layout tool.
GBTiler, a Gerber circuit board tiling program allows engineers, electronics hobbyists and other users with Gerber RS274X format files to "tile" or combine separate Gerber files -- circuit boards -- into a single, valid Gerber formatted file.
An active filter design assistant. Electrical engineers can use it to design and simulate analog active filters.

unPIC is a Perl script that disassembles Microchip microcontroller's HEX files. This is a powerful tool for all reverse engeneers that creates a well understandable assembly source from a binary file. Creates xrefs, labels, subroutines and much more...
Java source to C source translator, which allows to write MCU programs in Java. Now AVR are supported, others can be added. Convenient Java methods instead of manual register handling.
Quinessence is conceived as a package to perform optimal two-level realization of a boolean function using the classical Quine-McCluskey algorithm.
libLCS is a hardware description library in C++ aiming to be as powerfull and easy as the Verilog HDL. It currently supports logic gates, flipflops, clock, and facilitates delays, continuous assignments and variable value dumping into VCD files.
Analog Insydes is a Mathematica toolbox for symbolic analysis of analog electronic circuits. This project provides a set of free add-ons to Analog Insydes, including a Java front-end and a native netlister for Cadence's Analog Design Environment (ADE).

pyLPCTools is a replacement for the Flash Programming Tools use with the Philips(tm)/NXP(tm) LPC2xxx series of ARM based microcontrollers. pyLPCTools is a script together with some ARM assembly language and a Python user interface. Please Donate !!
"cif2tribes" is a console-based tool for converting integrated circuit layouts into maps usable in the game Tribes 2, as a 3D visualization aid. The project code is modular enough to be easily extended to different game engines and input file formats.
F- is an ANSish Forth that uses a VM generator to compile Forth into C-based VM suitable for living in a C-based (or assembly or HDL) microcontroller project. The VM supplies 32-bit math, I/O, multitasking and debugger in a ROM footprint as small as 4kB.
Grid-tools is a collection of scripts to aid in the submission of complex jobs to either Sun Grid Engine or LSF.
An Open-Source Library for Low-Power Approximate Computing Modules
The “lpACLib” library contains the VHDL description of accurate and approximate versions of several arithmetic modules (like adders and multiplier of different bit-widths) and accelerators. Moreover, it also provides the corresponding software behavioral models/implementations developed in C and MATLAB to enable quality characterization. Besides our novel designs, it also contains implementations for several state-of-the-art arithmetic modules and their approximate versions. This open-source library facilitates research and development in approximate computing at higher abstraction levels, and to facilitate reproducible research and comparisons. In case of usage, please refer to our publication: Muhammad Shafique, Rehan Hafiz, Semeen Rehman, Walaa El-Harouni, Jörg Henkel, "Cross-Layer Approximate Computing: From Logic to Architectures", Design Automation Conference (DAC), 2016.

Library of Approximate Adders
We provide MATLAB and Verilog Models of GeAr, and previously proposed adders (ACA-I, ETAII, ACA-II and GDA) at http://sourceforge.net/projects/approxadderlib/ GeAr is a low latency Generic Accuracy Configurable Adder that provides a higher number of potential configurations compared to state-of-the-art approximate adders, thus enabling a high degree of flexibility and trade-off between performance and output quality. These MATALB and Verilog models can allow software programmer as well as hardware designers to evaluate their code and design. To the best of our knowledge, this is the first open-source library of approximate adders that facilitates reproducible comparisons and further research and development in this direction across various layers of design abstraction. This work is a result of collaborative effort between Chair for Embedded Systems (CES) at Karlsruhe Institute of Technology (KIT), Germany and Vision Image and Signal Processing (VISpro) Lab at SEECS-NUST, Pakistan.
