Enhancing Word-Level Property Directed Reachability with LLM-Driven Semantic Guidance

Property Directed Reachability (PDR) is a prominent algorithm for hardware formal verification. However, bit-level PDR often struggles with datapath-heavy designs because bit-blasting obscures high-level semantics. While word-level PDR addresses this by reasoning over bit-vector and array theories, its performance rema...

Forbench: Symbolic Simulation Helps Make Your Testbench More Formal

Forbench is introduced, a word-level symbolic simulation framework that retains the familiar execution semantics of simulation but augments it with solver-backed symbolic signals and state transitions, enabling systematic exploration of RTL behaviors under symbolic inputs and conditions.
