This Artifact support the µArchiFI tool submission to FMCAD23. The abstract is reproduced below: This paper introduces µArchiFI, an open-source tool dedicated to the formal modeling and verification of microarchitecture-level fault injections and their effects on complex hardware/software systems. First, we address a system-level modeling problem, including an attacker model, which is automatically integrated into the Yosys toolchain. Second, we introduce verification strategies to evaluate the fault effects for software-level security. The practical use of µArchiFI is demonstrated on RISC-V use cases using state-of-the-art model-checking tools for hardware verification.
