Awesome Amaranth

A curated list of awesome projects using or building on the Amaranth project.

Please submit a PR if you have any suggestions!

Core Amaranth components

  • amaranth-soc Amaranth System-on-a-Chip Framework.
  • amaranth-stdio Amaranth stream based standard input and output components.
  • RFCs Process for Amaranth feature addition.
  • template-fpga Template repository for getting started with general Amaranth FPGA projects

Active Projects

  • Minerva is a CPU core that implements the RISC-V RV32IMZicsr instruction set built by the maintainer of Amaranth SoC.
  • Coreblocks is an experimental, modular out-of-order RISC-V core generator implemented in Amaranth.
  • Glasgow Glasgow Interface Explorer is a tool for exploring digital interfaces
  • LUNA is a toolkit for working with USB using FPGA technology, providing gateware and software to enable USB applications.
  • Lambdalib Lambdalib is a collection of cores, helpers and tools for Amaranth created and maintained by LambdaConcept.
  • ORBTrace Orbtrace is a lightweight, cost effective, USB2-HS Debug and Trace interface for ARM CORTEX-M processors.
  • Tiliqua Tiliqua is a powerful, open hardware FPGA-based audio multitool for Eurorack.
  • amaranth-exercises Graded exercises for Amaranth HDL
  • amaranth-lib-bl0x A collection of (useful) modules written in Amaranth-HDL.
  • amaranth-orchard Existing open source cores combined with wrappers and glue to enable Amaranth support.
  • amaranth-stubs Type stubs for Amaranth
  • hexastorm Hexastorm is a full toolkit for working with polygon lasers scanners using FPGA technology; and provides hardware, gateware, and software to enable laser scanning applications.
  • ili9341spi Driver for ILI9341 LCD display. Proving ground for niar.
  • learn-fpga-amaranth This repository contains code to follow the excellent learn-fpga tutorial by Bruno Levy from blinker to RISC-V using Amaranth HDL
  • mtkCPU mtkCPU is a simple, clear, hackable and very inefficient implementation of RiscV ISA in Amaranth HDL.
  • niar A small framework for building projects with Amaranth. Provides support for using CXXRTL, optionally with Zig and zxxrtl.
  • pytest-amaranth-sim Fixture to automate running Amaranth simulations.
  • sae RV32I softcore
  • sentinel Sentinel is a small RISC-V CPU (RV32I_Zicsr) written in Amaranth. It implements the Machine Mode privileged spec, and is designed to fit into ~1000 4-input LUTs or less on an FPGA.
  • smolarith Small arithmetic soft-cores for smol FPGAs.

Companies using Amaranth

  • ChipFlow Custom ASIC platform
  • LambdaConcept On-demand software development and hardware programming for a wide range of embedded systems.

Inactive Projects

Projects that have seen no updates for >6 months. There have been many changes in Amaranth in that time period.

Here be dragons, YMMV.
