FuseSoC

Introduction

FuseSoC is an award-winning package manager and a set of build tools for HDL (Hardware Description Language) code.

Its main purpose is to increase reuse of IP (Intellectual Property) cores and be an aid for creating, building and simulating SoC solutions.

FuseSoC makes it easier to

• reuse existing cores
• create compile-time or run-time configurations
• run regression tests against multiple simulators
• port designs to new targets
• let other projects use your code
• set up continuous integration

To learn more about FuseSoC head over to the User Guide.

Getting started

Installing the latest release

FuseSoC works on Linux, Windows, and macOS. It is written in Python and can be installed like any other Python package through "pip". Please refer to the full list of system requirements and installation instructions in the Installation section in the User Guide.

Quick start

To check if FuseSoC is working, and to get an initial feeling for how FuseSoC works, you can try to simulate a simple hardware design from our core libray.

First, create and enter an empty workspace

mkdir workspace
cd workspace

Install the FuseSoc base library into the workspace

fusesoc library add fusesoc-cores https://github.com/fusesoc/fusesoc-cores

Get a list of cores found in the workspace

fusesoc core list

If you have any of the supported simulators installed, you can try to run a simulation on one of the cores as well. For example, fusesoc run --target=sim i2c will run a regression test on the core i2c with Icarus Verilog. If you want to try another simulator instead, add e.g. --tool=modelsim or --tool=xcelium between run and i2c.

fusesoc --help will give you more information on commands and switches.

Did it work? Great! FuseSoC can be used to create FPGA images, perform linting, manage your IP libraries or do formal verification as well. Check out the online documentation documentation to learn more about creating your own core files and using existing ones. If it didn't work, please get in touch (see below).

Next steps

A good way to get your first hands-on experience with FuseSoC is to contribute to the LED to Believe project. This project aims to used FuseSoC to blink a LED on every available FPGA development board in existence. There are already around 40 different boards supported. If your board is already supported, great, then you can run your first FuseSoC-based design. If it's not supported, great, you now have the chance to add it to the list of supported boards. Either way, head over to LED to Believe to learn more and see how to go from a blinking LED to running a RISC-V core on an FPGA.
