Install RyuSim on your system.

Quick Install

The fastest way to install RyuSim:

curl -fsSL https://ryusim.seiraiyu.com/install.sh | bash

The installer auto-detects your architecture and glibc version, then downloads the most compatible build.

Platform Support

RyuSim is built and tested on the following Linux distributions:

Distribution	Version	glibc
Ubuntu	24.04 LTS	2.39
Ubuntu	22.04 LTS	2.35
Debian	13 (Trixie)	2.40
Debian	12 (Bookworm)	2.36
Fedora	42	2.41
Fedora	40	2.39
Rocky Linux	10	2.39
Rocky Linux	9	2.34

Other Linux distributions with glibc 2.34+ should also work. The installer auto-detects compatibility.

Windows users: RyuSim runs under WSL2 (Windows Subsystem for Linux). Install Ubuntu 24.04 in WSL2, then use the installer above.

System Requirements

Python 3.10+ — Required for cocotb testbenches
glibc 2.34+ — Rocky Linux 9 or newer (installer checks automatically)
Clang 18+ — Required to compile simulation models (the installer checks for this)

Install Dependencies

Install the required tools before running the RyuSim installer:

Ubuntu / Debian

sudo apt install clang cmake python3 python3-pip

Fedora

sudo dnf install clang cmake python3 python3-pip

Rocky Linux / RHEL 9

sudo dnf install epel-release && sudo /usr/bin/crb enable && sudo dnf install clang cmake python3 python3-pip

Rocky Linux / RHEL 10+

sudo dnf install clang cmake python3 python3-pip

Install cocotb (RyuSim fork)

RyuSim uses cocotb for Python-based testbenches. Until RyuSim support is merged upstream, install cocotb from the Seiraiyu fork:

pip install git+https://github.com/Seiraiyu/cocotb.git@feat/ryusim-simulator-support

This fork adds the RyuSim simulator runner and Makefile.ryusim to cocotb's build infrastructure. Once upstream cocotb includes RyuSim support, you can switch to the official release with pip install cocotb.
