Chiplet，进展如何

Core Viewpoint - The article discusses the evolution and significance of Chiplet technology in accelerating AI development, highlighting its advantages over traditional chip designs [2][20]. Group 1: Chiplet Definition and Evolution - Chiplet design is defined as multiple chips within the same package that communicate using signals optimized for intra-package communication [4]. - The evolution of chip technology includes multi-chip modules (MCM), multi-chip packages (MCP), and various advanced packaging techniques such as NAND flash stacking and AMD's VCache technology [2][4]. Group 2: Advantages of Chiplet Technology - Chiplets allow for the division of large designs that cannot fit on a single chip due to reticle size limitations [4]. - Smaller Chiplets improve yield rates compared to larger chips, making them more cost-effective [4]. - Advanced process node costs can range from $30 million to $50 million, and Chiplets help limit the use of expensive nodes to profitable areas [4]. - Chiplets facilitate the generation of more SKUs and accelerate time-to-market with lower non-recurring engineering costs [5][6]. - They enable the mixing of different wafer technologies, such as memory and logic circuits [5]. - Some technologies, like SRAM, do not scale down with process nodes, making Chiplets a viable solution [5]. - Chiplets can lead to energy savings [5]. Group 3: Economic Impact and Market Predictions - The use of Chiplets is exemplified by Xilinx's large FPGA manufacturing, which demonstrates their economic advantages for large applications, especially in AI [9]. - AMD's multi-chip designs, such as Zen 5 and Zen 5c, illustrate the economic production of new SKUs by utilizing different core chips [13]. - The article predicts that the chip market will reach $600 billion by 2031, driven by significant capital expenditures in AI systems [20].
