MEIC is an iterative debugging framework that uses multiple Large Language Models (LLMs) to address both syntax and function errors in Register Transfer Level (RTL) Verilog code. The system achieves a 93% fix rate for syntax errors and 78% for function errors, demonstrating up to a 48x speedup over human experts in specific debugging scenarios.
Key insights
- An iterative debugging process, inspired by human practices, can effectively manage the inherent uncertainties and variabilities in LLM outputs for complex tasks like RTL debugging.
- Integrating LLMs into a structured framework with feedback loops significantly enhances their debugging performance, even for less capable models like GPT-3.5.
- Optimizing LLM temperature settings involves a trade-off, where higher temperatures can improve fix rates for complex function errors but may reduce precision for simpler syntax errors.
