Explore methods for integrated circuit decomposition and hardware decompilation in this conference talk. Delve into techniques for extracting functionality from netlists at a higher abstraction level to reconstruct behavioral Register Transfer Level (RTL) code. Learn about the concept of "hardware decompilation" and its parallels with software decompilation. Discover how existing netlist structure recovery techniques fit into the decompilation pipeline and examine new approaches unique to hardware decompilation. Gain insights into solving computationally hard firmware and hardware security problems, including emerging nondestructive counterfeit detection methods and process automation for hardware security. Compare parsing, recompiling, and control flow concepts between software and hardware domains. Witness a signature matching demo and understand the applications of isomorphism-based matching, topology-based matching, and subgraph mining in hardware decompilation.
