CLOSER-Bench: Evaluating Budgeted Cross-Stage Design Closure for Hardware Agents

CLOSER-Bench is introduced, a controlled evaluation protocol for budgeted cross-stage design closure and a ten-task pilot spanning RTL repair, mutation-based verification, coverage, PPA optimization, design-space exploration, cross-model debugging, and security establishes the executable harness.

RTLCurator: Label-Efficient Data Curation for RTL Generation

RTLCurator is presented, which learns a behavior-aware compatibility prior by contrasting each specification with implementations that fail simulation, and calibrates it to a new corpus using a small number of validated pairs, and constructs the retained subset by balancing alignment, representation coverage, and RTL s...

When Fuzzing Meets Understanding: LLM-Driven Semantic Test Generation for RTL Verification

ChipFuzzer is proposed, a hardware fuzzing framework that leverages the semantic reasoning capabilities of large language models (LLMs) to improve fuzzing effectiveness and improves average condition coverage and bug detection rate over the strongest baseline.
