ROAST is an open-source Python framework that simplifies the development of complex validation test suites. To accomplish this, ROAST provides a collection of interfaces that allows test developers to build test suites in a highly structured manner.

Key features:

• Compose systems from Xilinx or custom components
• Define systems composed from various configuration sources
• Heirarchical configuration system
• Randomized data provider for randomized testing
• Generic APIs for simplified usage and access
• Plugin system for extensibility

ROAST consists of three packages:

• roast: Core functionality that includes interfaces, plugin framework, configuration management, and more
• roast-xilinx (recommended: plugin for roast that includes Xilinx specific functionality such as board acquisition, PetaLinux building, Vitis wrapper, and more.
• pytest-roast (optional): plugin for pytest that includes pytest fixtures for accelerated test development when using pytest as a test runner. Features includes target automation, scenario generation, and configuration generation.
