New benchmark reveals LLM limitations in circuit design netlist manipulation

Researchers have introduced NetlistBench, a new benchmark designed to evaluate the reliability of Large Language Models (LLMs) in understanding and manipulating SPICE netlists, which are crucial for circuit design. The benchmark includes 2,342 cases across 24 task families, assessing performance on tasks like parameter recognition, connectivity edits, and equivalence judgment. Results show that while LLMs perform well on simple local edits, their accuracy drops significantly for more complex operations like device addition and equivalence judgment, highlighting netlist reliability as a bottleneck for LLM-based circuit design automation. AI

IMPACT Identifies a key bottleneck in applying LLMs to circuit design, potentially guiding future model development for specialized engineering tasks.

    NetlistBench: Evaluating LLM Reliability in SPICE Netlist Recognition and Manipulation

    arXiv:2608.12197v1 Announce Type: cross Abstract: Large Language Models (LLMs) are increasingly used in circuit design workflows, yet their reliability on simulator-facing SPICE netlist recognition and manipulation remains poorly understood and is rarely separated from high-level…
