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.

vrq is verilog parser that supports plugin tools to process verilog. Current plugins include tools to perform x-propagation and to auto build hiearchy.

bel_fft is a FFT co-processor that can calculate FFTs with arbitrary radix. It is a hardware implementation of the free software Kiss FFT ("Keep it simple, Stupid!"). The target was to allow a simple replacement of the software code with the hardware implementation. Therefore bel_fft comes with a software driver that is compatible with the Kiss FFT routines. bel_fft also has a modular architecture and allows interfacing different bus architectures. So far AMBA AXI, Altera's Avalon bus and the Wishbone bus are supported. However, bel_fft's architecture allows an easy adaptation to further bus architectures (e.g. AMBA AHB). It comes with a Java wizard to configure the co-processor and to generate all required files (e.g. twiddle ROMs). It comes with integration into Xilinx Vivado, EDK, and Altera QSYS and includes example designs for Xilinx Zynq and with PCI-Express core (including Linux driver and application). bel_fft is distributed under the GNU Lesser Public License 2.1.

VeriWell is a full Verilog simulator. It supports nearly all of the IEEE1364-1995 standard, as well as PLI 1.0. Yes, VeriWell *is* the same simulator that was sold by Wellspring Solutions in the mid-1990 and was included with the Thomas and Moorby book

CoreTML framework is an open-source template-based configuration system allowing the developer to create parametrized templates by inserting special content to any text files. Its main purpose is to serve as a toolkit for semiconductor IP core creation (based on VHDL/Verilog).

This is a collection of tools and a code library to assist engineers who are developing SystemVerilog based verification environments. Components include utility libraries, scoreboard and shutdown manager implementation, register tool, etc.

FSMDesigner is a C++ based implementation for a Finite State Machine (FSM) design tool with integrated Hardware Description Language (HDL) generation. FSMDesigner4 uses the Simple-Moore FSM model guaranteeing efficient fast complex control circuits.

libhdlfltp is a VHDL library of floating point operators, all of which are parametrized, synthesizable to FPGAs and cover a number of the core operators in math.h.

A collection of useful software packages to perform engineering tasks, especially electrical engineering and chip design. All packages come as shrink-wrapped installers for Apple's Mac OS X.

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.

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.

Automatic build management for VHDL and Verilog projects. The automatic dependency resolver finds the exact subset of sources, and the correct order they must appear in required to build a project. A Makefile automates the actual build itself.

Student Project

Platform for advanced open source IP-Core development, i. e. dynamic memory controllers for FPGAs.

Convert C++ software programs into synthesisable Verilog using the Clang compiler frontend to parse and SystemC for intermediates.

Labcoat for SuperWikia Alpha fabrication manages new or revised fabrication processes. Its 'Cleanroom' applets allow codesmiths to access the lab environment, used to create semiconductors, substrate prototypes, chipset instruction blocks and other Labcoat projects. Our extensions in future releases will include UML support for C#/C++ conforming projects, import/export architecture schematics and refactoring sub-projects.

NOCEXplore is a Network-on-Chip design exploration tool based on SystemC. It includes libraries and executables for easy and fast upgradeable NoC models and a set of shell scripts. The project started during the PhD of Stefano Gigli at DII of Universita' Politecnica delle Marche (http://www.dii.univpm.it/) under the supervision of Prof. Massimo Conti and contribution of several students.

OpenVGA is an free and open FPGA-based implementation of a VGA compatible graphics adapter, and utilising low-cost hardware. The project includes the PCB schematic and artwork, Verilog HDL, firmware assembly code, and driver source code.

Design and implementation of silicon and software for baseband processors conforming to IEEE wireless standards. Initial focus on WiMAX and WiFi.

A methodology to create netlists for printed circuit board layout using a novel PCB specific HDL as the source language.

Powerful Verilog Preprocessor. PLP stands for Perl Pre-processor. Perl is used as "control language" that is embedded in the Verilog code (or any other code) to generate code on the fly. It is used commonly as a Verilog pre-processor but can be used with any target/output language (C, C++, Java, VHDL, plain text etc)
