Renode

What Renode is

Renode is an open-source framework for emulating computer systems, from processors and peripherals to sensors, interconnects, and multi-node setups. Teams can run unmodified target software before physical hardware is available and use repeatable CI/CD tests to catch regressions early. Platforms can be assembled from reusable components or built as bespoke models. Supported architectures include ARM, x86, RISC-V, SPARC, POWER, Xtensa, and MSP430X; the project also reports support for more than 1,200 boards. Renode includes snapshots and restore, debugging, network simulation, and automation access. Listed integrations range from Verilator, Questa, and SystemC to development environments, CI systems, and robotics tools. It runs on Windows, macOS, and Linux and is free under the MIT license. Renode requires dotnet 6.0 or later, and its Linux portable package needs GTK2 for the UI. Antmicro offers commercial and enterprise support for modeling, integrations, and CI infrastructure.

Who it suits

Renode suits product development and silicon teams that need to run target software or test modeled systems before hardware is available. It also fits teams building repeatable CI/CD tests across supported architectures and boards.

Limits

Renode is free and has an open-source MIT license. The listed technical requirements are dotnet 6.0 or later, plus GTK2 for the Linux portable package when the UI is enabled.

Getting started

1. Open the Renode website
2. Choose a Linux, macOS, or Windows package
3. Use a portable package or Windows installer where appropriate
4. Install dotnet 6.0 or later
5. Install GTK2 on Linux when using the portable package with its UI

Verdict

Renode combines system emulation with automation and repeatable testing across a broad set of architectures. Check its runtime requirements and available integrations against your development setup.
