Renode was created by Antmicro as a virtual development tool for multi-node embedded networks (both wired and wireless) and is intended to enable a scalable workflow for creating effective, tested and secure IoT systems.
With Renode, developing, testing, debugging and simulating unmodified software for IoT devices is fast, cost-effective and reliable.
Supported architectures include:
- ARMv7 and ARMv8 Cortex-A, Cortex-R and Cortex-M
- x86 and x86_64
- RISC-V
- SPARC
- POWER
- Xtensa
Renode was created based on many years of experience with the development of software for embedded systems - both for gateways, on-board computers, as well as sensor nodes and microcontrollers.
Testing and developing physical embedded systems is difficult due to poor reproducibility and lack of insight into the current state of a system, especially in multi-node scenarios.
Renode addresses this issue by letting you run unmodified binaries identical to the ones you would normally flash onto their target hardware on a virtual board or system of boards.
One important aspect of the tool is that it simulates not only CPUs but entire SoCs (e.g., heterogeneous multicore SoCs and various peripherals) as well as the wired or wireless connections between them, allowing users to address complex scenarios and test real production software.
Nightly builds of Renode for all systems are available at builds.renode.io.
The latest builds are always available as renode-latest.* packages.
The following packages formats are available:
renode-latest.linux-portable-dotnet.tar.gz- portable Linux package, embeds dotnet runtimerenode-latest.linux-portable.tar.gz- portable Linux package, embeds Mono runtimerenode-latest.linux-dotnet.tar.gz- Linux prebuilt archive, requires dotnet installed on hostrenode-latest.pkg.tar.xz- Arch Linux packagerenode-latest.x86_64.rpm- Red Hat / Fedora packagerenode-latest.deb- Debian-based distribution packagerenode-latest.dmg- macOS packagerenode-latest.zip- Windows portable package, without installerrenode-latest.msi- Windows installerrenode-latest.tar.xz- Renode sources
Stable, numbered releases and their release notes are available in the Releases section on GitHub.
If you are a Linux user, the easiest way to use Renode is to download the latest linux-portable from the releases section and unpack it using:
mkdir renode_portable
wget https://builds.renode.io/renode-latest.linux-portable.tar.gz
tar xf renode-latest.linux-portable.tar.gz -C renode_portable --strip-components=1
To use it from any location, enter the created directory and add it to the system path:
cd renode_portable
export PATH="`pwd`:$PATH"
Please note that the portable package requires GTK2 to be available on the host to run with the UI enabled.
Follow the Additional Prerequisites section if you wish to use Robot Framework for testing. Otherwise, proceed to the 'Running Renode' section.
Renode requires Mono >= 5.20 (Linux, macOS) or .NET Framework >= 4.7 (Windows). On all systems, you can also use dotnet >= 6.0.
To install dotnet on Linux, follow the official installation guide.
Alternatively, install the mono-complete package as per the installation instructions for various Linux distributions you can find on the Mono project website.
To install dotnet on macOS, follow the official installation guide.
Alternatively, for Mono-based setups, you can download the Mono package directly from the Mono project website.
To install modern dotnet (as opposed to .NET Framework) on Windows, follow the official installation guide. The .NET SDK includes runtime, so you will be able to build and run Renode.
On Ubuntu 20.04, you can install the remaining dependencies with the following command:
sudo apt-get install policykit-1 libgtk2.0-0 screen uml-utilities gtk-sharp2 libc6-dev libicu-dev gcc python3 python3-pip
If you are running a different distribution, you will need to install an analogous list of packages using your package manager; note that the package names may differ slightly.
Go to the releases section of this repository and download an appropriate package for your system.
Install Renode with your preferred package manager using the provided *.deb, *.rpm or *.pkg.tar.xz packages.
Use the provided *.dmg as normal.
Additionally, to use Renode from the command line on macOS, create appropriate aliases by adding alias renode='mono /Applications/Renode.app/Contents/MacOS/bin/Renode.exe' and alias renode-test='/Applications/Renode.app/Contents/MacOS/tests/renode-test' to your .bashrc or .zshrc file, depending on the shell you're using.
Install Renode from the provided *.msi file. The installer will allow you to add icons to your Desktop and/or Start Menu and an entry to your PATH.
To write and run test cases, Renode integrates with the Robot testing framework.
This requires you to install Python 3 (on Windows, you will also need Cygwin - see the advanced installation instructions) with pip (note that the relevant package may be called python-pip or python3-pip on Linux).
Once you have Python 3 and pip, install additional modules:
python3 -m pip install -r tests/requirements.txt
Additionally, each of the tools in the /tools subdirectory may contain a requirements.txt file separate from Renode's requirements.
Install them in your virtual environment with pip install -r requirements.txt.
For information on building Renode from source, see the documentation.
After following the instructions above on installation from a package, you should have the renode command available system-wide:
renode [flags] [file]
If you built it from source, navigate to the relevant directory and use:
./renode [flags] [file]
The optional [file] argument allows you to provide the path to a script to be run on startup.
The script allows several optional flags, the most useful of which are presented below:
-p Remove steering codes (e.g., colours) from output
-P INT32 Instead of opening a window, listen for Monitor commands on the specified port
-e COMMAND Execute command on startup (executed after the optional script). May be used multiple times
--console Run the Monitor in the console instead of a separate window
--disable-gui Disable XWT GUI support. It automatically sets HideMonitor
--hide-monitor Do not show the Monitor window
--hide-log Do not show log messages in console
--hide-analyzers Do not show analyzers
-v Print version and exit
-h Display help and usage information
Renode can be run on Windows systems with a similar set of optional flags.
Below, you can see a piece of firmware running on simulated hardware. The Renode Monitor is visible alongside an analyzer window displaying UART output and logger. For more information about this particular setup, see its dedicated repository.
renode-run is a Python script that downloads and runs Renode, and lets you easily run demos available in Renodepedia as well as local ELF files.
Go to the repository for usage instructions.
renode-run relies on a portable package and its main advantage is the ease of updating Renode to the latest nightly build using a single command.
pyrenode3 is a A Python library for interacting with Renode programmatically.
Go to the repository for usage instructions.
If you want to run Renode in Docker, you can use prebuilt images available on Docker Hub.
To start Renode in interactive mode on Linux, assuming you have Docker installed in your system, run one of the following:
- For the latest numbered version build:
docker run -ti -e DISPLAY -v $XAUTHORITY:/home/developer/.Xauthority --net=host antmicro/renode:latest - For a nightly mono build:
docker run -ti -e DISPLAY -v $XAUTHORITY:/home/developer/.Xauthority --net=host antmicro/renode:nightly - For a nightly dotnet build:
docker run -ti -e DISPLAY -v $XAUTHORITY:/home/developer/.Xauthority --net=host antmicro/renode:nightly-dotnet
This will display the Renode Monitor window. Alternatively, you can provide your custom command at the end of the line above.
To run the image in console mode without X server passthrough, run:
docker run -ti antmicro/renode bash
You can add more -v switches to the command to mount your own directories.
