Tenstorrent releases RiescueD, a powerful framework for writing direct tests in RISC-V assembly

September 2, 2025 -- Over the coming months, Tenstorrent plans to open source a suite of tools under the RiESCUE umbrella, which provides a suite of python scripts and libraries for generating RISC-V tests.

Tenstorrent would first like to announce the release of RiescueD, the RiESCUE Directed Test Framework. This is a powerful framework for writing directed tests in RISC-V assembly and provides library for test generator development, with features including:

• Randomization: Random data and address generation
• Memory Management: Automatic page table generation and memory mapping
• Environment Simulation: Support for various privilege modes, paging modes, and virtualization
• OS Code Simulation: Pseudo OS for scheduling and exception handling

RiescueD works well with several popular RISC-V simulators:

• Spike: RISC-V ISA simulator
• Whisper: Tenstorrent’s RISC-V Simulator
• QEMU: Full system emulation (coming soon)
