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.

Automatic coloring PCB - make a color circuit board for installation.
The program is designed for automatic coloring schemes of printed circuit boards for ease of installation. For its work requires some files with information on the printed circuit board, package generated by P-CAD. The basic principle: each type of component (identical components) are marked with a unique symbol that has its own color and style. This simplifies the visual search component on the board. The program also generates a text list of components, where the marks, what type of components is associated with which character on the circuit board.

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.
Much like SPICE does for circuit designers, SUGAR provides for MEMS designers a tool for quickly specifying their devices in a netlist type format and analyzing their devices with different simulation and mathematical techniques.
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.
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.
