Associated research topic

The associated paper proposes MorFuzz, described as a processor fuzzer for discovering software-triggerable hardware bugs. According to the paper abstract, MorFuzz uses runtime information to generate instruction streams with valid formats and meaningful semantics, introduces an input structure for multi-level runtime mutation primitives, and applies instruction morphing to mutate instructions dynamically. [C3]

The paper reports evaluation on three open-source RISC-V processors—CVA6, Rocket, and BOOM—and states that MorFuzz discovered 17 new bugs, including 13 assigned CVEs. [C4]
