Inverter Redistribution through Self-Dual and Self-Anti-Dual Function Transformation

And-Inverter Graph (AIG)-based logic synthesis has been a cornerstone of digital design automation for several decades. While numerous optimization techniques have been developed for both technology-independent and technology-dependent synthesis …

P-IC3: Racing Three IC3 Workers with Different Literal-Deletion Orders

Parallel portfolios provide a practical means of exploiting the behavioral diversity of IC3/PDR heuristics. Building on the observation that different literal-deletion orders can lead to different generalized clauses and verification trajectories, we …

APEX-RBD: Mixed-Precision Exploration Framework for Hardware-Efficient Robot Dynamics Accelerator Design

Rigid Body Dynamics (RBD) forms the computational core of real-time robotic control, but its immense computational complexity creates a performance bottleneck that necessitates dedicated hardware accelerators. However, the substantial hardware …

Forbench: Symbolic Simulation Helps Make Your Testbench More Formal

Simulation remains the dominant approach in pre-silicon verification due to its ease of deployment and intuitive workflow. However, as simulation only explores a limited subset of possible execution traces within feasible time budgets, it often fails …

IC3-Evolve: Proof-/Witness-Gated Offline LLM-Driven Heuristic Evolution for IC3 Hardware Model Checking

IC3, also known as property-directed reachability (PDR), is a commonly-used algorithm for hardware safety model checking. It checks if a state transition system complies with a given safety property. IC3 either returns UNSAFE (indicating property …

A-IC3: Learning-Guided Adaptive Inductive Generalization for Hardware Model Checking

The IC3 algorithm represents the state-of-the-art (SOTA) hardware model checking technique, owing to its robust performance and scalability. A significant body of research has focused on enhancing the solving efficiency of the IC3 algorithm, with …

Beyond Overlap Metrics: Rewarding Reasoning and Preferences for Faithful Multi-Role Dialogue Summarization

Multi-role dialogue summarization requires modeling complex interactions among multiple speakers while preserving role-specific information and factual consistency. However, most existing methods optimize for automatic metrics such as ROUGE and …

And-Inverter Graph (AIG)-based logic synthesis has been a cornerstone of digital design automation for several decades. While numerous optimization techniques have been developed for both technology-independent and technology-dependent synthesis …

LeGend: A Data-Driven Framework for Lemma Generation in Hardware Model Checking

Property checking of RTL designs is a central task in formal verification. Among available engines, IC3/PDR is a widely used backbone whose performance critically depends on inductive generalization, the step that generalizes a concrete …

AutoINV: Automated Invariant Generation Framework for Formal Verification on High-Level Synthesis Designs

High-level synthesis (HLS) transforms an algorithmic description of hardware from a higher abstraction (e.g., C/C++) into a register-transfer level (RTL) design, offering reduced development time and greater flexibility in design space exploration. …
