Parses RTL into a knowledge graph that models signals, registers and hierarchies as nodes and data/control/synchronization as edges, scaling from millions of RTL lines to billions of gates. Implements a GraphRAG system that extracts entities from unstructured metadata, computes metrics (influence, distance, signal role) to rank vulnerabilities, and suggests/installs instrumentation for mitigation and ML‑based Trojan detection. A case study on the Ibex processor finds specific desynchronization and spoofing exploit locations, demonstrating the pipeline is practical and effective.
