GHDL
VHDL 2008/93/87 simulator
...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. -

SmGen
Verilog Finite State Machine (FSM) Code Generator
SmGen is a finite state machine (FSM) generator for Verilog. On the other hand, it is not an FSM entry tool. The input is behavioral Verilog with clock boundaries specifically set by the designer. SmGen unrolls this behavioral code and generates an FSM from it in synthesizable Verilog. Clock boundaries are explicitly provided by the designer so there is good control on the expected timing -

Wheefun Computer Prototyping Kit
A Toolkit for Designing Computers
This package is designed for people who are a) interested in writing emulators or b) integrating this level of detain into their applications (e.g., a video game). The ability to do this is useful because a) it allows for tinkering far before physical implementation of the design is. In addition to a strong core, WFCPK will also include modules emulating various processors (e.g., the MOS 6502 and the Zilog Z80) as well as the Video-Audio Interface (a custom VGA-compatible display and... -

GPS to Radio-controlled Clock
GPS to Radio-controlled Clock
The purpose of this simple DIY project is to build an electronic circuit that received the GPS time signal, convert it to the radio-controlled clock format, and transmit that signal to the clock. Once built, there is no need for setup and maintenance, all you need is put this unit close to the window to receive GPS signal, and it will transmit the time signal to your radio-controlled clock. -

lpACLib
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... -

ghdl-updates
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. -

PLP
Powerfull pre-processor
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) -

cMIPS
cMIPS - an FPGA ready VHDL model for 5-stage pipeline, MIPS32r2 core
This project was moved to https://gitlab.c3sl.ufpr.br/roberto/cmips The code here is no longer up to date. The VHDL model mimics the pipeline design described in Patterson & Hennessy's book (Computer Organisation and Design) and is an almost complete implementation of the MIPS32r2 instruction set. The TLB and assorted control registers will be included soon (as of fev 2015). The model was synthesized for an Altera EP4CE30F23. The model uses up 15% of combinational blocks and 5%... -

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... -
