Large language models (LLM) have shown great potential in various fields, but their application in professional fields, such as chip design, still faces challenges. ChipAlign launched by NVIDIA is an innovative solution that cleverly combines the advantages of general instruction alignment LLM and chip-specific LLM, effectively improving the performance of the model in the field of chip design. ChipAlign uses a unique model merging strategy to integrate the capabilities of the two models without additional training, significantly reducing computing resource requirements.
In today's context of rapid technological development, large language models (LLM) play an important role in multiple industries, helping to automate tasks and improve decision-making efficiency. However, in specialized fields such as chip design, these models face unique challenges. NVIDIA's recently launched ChipAlign is designed to address these challenges by combining the benefits of general-purpose instruction-aligned LLM with chip-specific LLM.
ChipAlign adopts a new model merging strategy that does not require a tedious training process and uses geodesic interpolation methods in geometric space to smoothly merge the capabilities of the two models. Compared with traditional multi-task learning methods, ChipAlign directly combines pre-trained models, avoiding the need for large data sets and computing resources, thus effectively retaining the advantages of the two models.
Specifically, ChipAlign achieves results through a series of carefully designed steps. First, it projects the weights of chip-specific and instruction-aligned LLM onto a unit n sphere, then performs geodesic interpolation along the shortest path, and finally rescales the fused weights to ensure that their original characteristics are maintained. . This innovative approach resulted in significant improvements, including a 26.6% improvement in performance on the command following benchmark.
In practical applications, ChipAlign demonstrated its excellent performance in multiple benchmark tests. In the IFEval benchmark, it achieved a 26.6% improvement in instruction alignment; in the OpenROAD QA benchmark, ChipAlign's ROUGE-L score increased by 6.4% compared to other model merging technologies. In addition, in industrial chip quality assurance (QA), ChipAlign also surpassed the baseline model with an advantage of 8.25%, performing well.
NVIDIA's ChipAlign not only solves pain points in the chip design field, but also demonstrates how to narrow the gap in large language model capabilities through innovative technical means. The application of this technology is not limited to chip design. It is expected to promote progress in more professional fields in the future, showing the huge potential of adaptable and efficient AI solutions.
