Agentic AI Framework Automates RTL Verification, Boosting Coverage.

Functional verification is a critical and labor-intensive part of integrated circuit design, where undetected bugs can lead to costly hardware respins. Current AI methods for this task often struggle with maintaining context across different components and linking coverage directly to design specifications. GoGoTB introduces an agentic framework to overcome these limitations. This new system features an agentic execution layer that separates deterministic actions from LLM reasoning, a dynamic knowledge base for methodology and design expertise, and a coverage framework that ties every verification point back to a specific design requirement. This ensures that any remaining gaps are traceable and addressable. Evaluated on eight register transfer level (RTL) designs, GoGoTB successfully generated complete verification environments and achieved high levels of line, branch, toggle, and functional coverage, demonstrating a significant advancement over previous automated verification efforts.
