ARMOR: Accelerating RTL Simulation by Mitigating the Front-End Bottleneck Using Node Compression
Jiaping Tang, Jianan Mu, Zhiteng Chao +3
RTL simulation is indispensable in chip design. High-performance simulators typically lower each node in the RTL graph into an instruction sequence. Although this per-node lowering…
Rtl2lean: Automated RTL-to-Lean Translation with Hierarchical Theorem Generation and Lemma Reuse
Hongqin Lyu, Junxing Dong, Yonghao Wang +3
Formal verification with interactive theorem provers can provide strong correctness guarantees for register transfer level designs, but applying it to existing SystemVerilog code r…
Arcane: An Assertion Reduction Framework through Semantic Clustering and MCTS-Guided Rule Exploring
Hongqin Lyu, Yonghao Wang, Zhiteng Chao +2
Assertion-based Verification (ABV) is essential for ensuring that hardware designs conform to their intended specifications. However, existing automated assertion-generation approa…
Pecker: Bug Localization Framework for Sequential Designs via Causal Chain Reconstruction
Jiaping Tang, Jianan Mu, Tianyun Ma +3
Debugging represents a time-consuming and labor-intensive task in hardware design, with bug localization constituting a substantial portion of this process. While spectrum-based bu…
CoverAssert: Iterative LLM Assertion Generation Driven by Functional Coverage via Syntax-Semantic Representations
Yonghao Wang, Yang Yin, Hongqin Lyu +8
LLMs can generate SystemVerilog assertions (SVAs) from natural language specs, but single-pass outputs often lack functional coverage due to limited IC design understanding. We pro…
From Indiscriminate to Targeted: Functionally Critical Signal-Driven Assertion Generation using LLMs for Efficient RTL Verification
Yonghao Wang, Hongqin Lyu, Boling Chen +9
Functional verification has become the most time-consuming phase in IC development, and Assertion-Based Verification (ABV) is key to reducing debugging time. However, existing LLM-…
