IODINE: a tool to automatically infer dynamic invariants for hardware designs

We describe IODINE, a tool to automatically extract likely design properties using dynamic analysis. A practical bottleneck in the formal verification of hardware designs is the need to manually specify design-specific properties. IODINE presents a way to automatically extract properties such as state machine protocols, request-acknowledge pairs, and mutual exclusion between signals from design simulations. We show that dynamic invariant detection for hardware designs can infer relevant and accurate properties.
