New IncreRTL framework enables LLMs to incrementally update hardware code when design requirements change, avoiding costly full regeneration

IncreRTL uses requirement-code traceability links to identify which code segments need updates when requirements evolve, enabling targeted regeneration instead of rebuilding entire designs

The framework addresses a key limitation of existing LLM-based RTL generation methods that remain static and struggle to adapt to changing specifications

Evaluated on a new EvoRTL-Bench dataset, IncreRTL shows significant improvements in regeneration consistency and efficiency compared to previous approaches

The solution represents progress toward making LLM-based RTL generation practical for real-world hardware engineering workflows
