The Decomposition and Combination Paradigms of Chiplet-Based Integrated Chips

Due to the waning of Moore's Law, the conventional monolithic chip architectural design is confronting hurdles such as increasing die size and skyrocketing cost. In this post-Moore era, the integrated chip has emerged as a pivotal technology, gaining substantial interest from both the academia and industry. Compared with monolithic chips, the chiplet-based integrated chips can significantly enhance system scalability, curtail costs, and accelerate design cycles. However, integrated chips introduce vast design spaces encompassing chiplets, inter-chiplet connections, and packaging parameters, thereby amplifying the complexity of the design process. This paper introduces the Optimal Decomposition-Combination Theory, a novel methodology to guide the decomposition and combination processes in integrated chip design. Furthermore, it offers a thorough examination of existing integrated chip design methodologies to showcase the application of this theory.
