GHDL
VHDL 2008/93/87 simulator
This directory contains the sources of GHDL, the open-source analyzer, compiler, simulator and (experimental) synthesizer for VHDL, a Hardware Description Language (HDL). GHDL is not an interpreter: it allows you to analyze and elaborate sources for generating machine code from your design. Native program execution is the only way for high-speed simulation. Full support for the 1987, 1993, 2002 versions of the IEEE 1076 VHDL standard, and partial for the 2008 and 2019 revisions. By using a code generator (LLVM, GCC or, x86_64/i386 only, a built-in one), it is much faster than any interpreted simulator. It can handle very large designs, such as leon3/grlib. GHDL runs on GNU/Linux, Windows and macOS; on x86, x86_64, armv6/armv7/aarch32, aarch64 and ppc64. You can freely download nightly assets, use OCI images (aka Docker/Podman containers), or try building it on your own machine. -

pyrpl
PyRPL turns your Red Pitaya into a powerful analog feedback device.
The Red Pitaya is a commercial, affordable FPGA board with fast analog inputs and outputs. This makes it useful for quantum optics experiments, in particular as a digital feedback controller for analog systems. Based on the open source software provided by the board manufacturer, PyRPL (Python RedPitaya Lockbox) implements many devices that are needed for optics experiments with the Red Pitaya. PyRPL implements various digital signal processing (DSP) modules (see features below). It allows to arbitrarily interconnect the available DSP modules and retrieve signal values on timescales below 1 ms. The graphical user interface (GUI) provides a realtime display of the various measurement instruments and allows the easy configuration of DSP signal chains and feedback controllers. At the highest abstraction level, arbitrary feedback sequences can be defined to fulfill tasks as complex as approaching and locking a resonance of a high-finesse Fabry-Perot cavity (tested up to finesse=100,000). -

OpenSOC86
Open implementation of the x86 architecture
OpenSOC86 is an open implementation of the x86 architecture in Verilog. The current version only implements the 16-bit part (real mode). The processor is a pipelined architecture clocked at 100 MHz in a Cyclone II speed grade -6. Therefore it can be seen as similar to a 486 in real mode. Several peripherals are also implemented in a somewhat minimalistic way, but enough to be able to boot an IBM PCXT compatible bios and MSDOS 6.22. The current implementation is only proven to boot the bios and DOS in simulation. The system is targeted to run on the DE2-70 board. In order to run the system in hardware a SDRAM and SRAM controller need to be added. These are currently in development. -

Notepad++ Verilog Plugin
Verilog plugin for Notepad++
Verilog processor for Notepad++. Current features: - Instantiate a module - Insert registers/wires from a module - Generate a test bench template - Automatically inserts a default header for a test bench - Insert a clocked always block v1.2.0 now supports ANSI and non-ANSI module declarations. To use this plugin, select the module declaration (including parameter and I/O definitions below for non-ANSI) and click SHIFT-CTRL-C. This selects the module and parses its components. After this, all other functions are available. -

AWS EC2 FPGA
AWS EC2 FPGA hardware and software development Kit
AWS EC2 FPGA Development Kit is a set of development and runtime tools to develop, simulate, debug, compile and run hardware-accelerated applications on Amazon EC2 F1 instances. It is distributed between this GitHub repository and FPGA Developer AMI - Centos/AL2 provided by AWS with no cost of development tools. After creating an FPGA design (also called CL - Custom logic), developers can create an Amazon FPGA Image (AFI) and easily deploy it to an F1 instance. AFIs are reusable, shareable and can be deployed in a scalable and secure way. Development experience leverages an optimized compiler to allow easy new accelerator development or migration of existing C/C++/openCL, Verilog/VHDL to AWS FPGA instances. Fully custom hardware development experience provides hardware developers with the tools required for developing AFIs for AWS FPGA instances. -

ApproxAdderLib
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. -
