- GoGoTB ties reported coverage data to specification requirements, reducing the risk of costly silicon respins from undetected bugs.
Researchers have released GoGoTB, an agentic AI framework designed to automate functional verification in integrated circuit (IC) design. The framework uses large language models (LLMs) to ensure that all components of a chip design work together correctly, reducing the risk of costly errors that can require expensive silicon respins.
GoGoTB Uses Multi-Turn LLM Calls to Detect Interface Mismatches
GoGoTB is an agentic framework that leverages large language models to automate the functional verification of integrated circuits. Traditional verification processes are manual and time-consuming, often missing critical bugs that can lead to expensive respins. Existing LLM-based approaches generate each component through independent single-turn calls with no shared context, leaving interface mismatches undetected and reported coverage disconnected from specification requirements. GoGoTB addresses these issues by generating and verifying each component through multi-turn calls with shared context, ensuring that all parts are compatible and meet specification requirements.
Shared Context Across Components Makes Verification More Cohesive
The framework introduces several key improvements over existing LLM-based approaches. It ensures that interface mismatches are detected and reported coverage is connected to specification requirements. This means that the verification process is more thorough and less likely to miss critical bugs. The framework also maintains shared context across different components, making the verification process more cohesive and effective.
Reducing Costly Silicon Respins Benefits Manufacturers and Consumers
For chip designers, GoGoTB represents a significant advancement in the verification process. It reduces the time and effort required to ensure that chip designs are error-free, ultimately lowering the cost and risk of chip production. A single missed bug that escapes to silicon can trigger a costly respin. This can lead to faster development cycles and more reliable chips, benefiting both manufacturers and consumers. For everyday users, this means more reliable electronics and potentially faster adoption of new technologies.
