Cadence has achieved a significant milestone by designing and taping out its first-ever system chiplet, marking a groundbreaking advancement in chiplet realization capabilities. Utilizing the innovative Cadence Chiplet Architecture and Framework, along with Cadence IP, EDA technologies, and select Arm IP, this system chiplet exemplifies the seamless integration of multiple chiplet dies within a single package. This pioneering development opens new possibilities for industries such as automotive, high-performance computing (HPC), and data centers, enabling customers to collaborate closely with Cadence's Silicon Solutions Group to create cutting-edge chiplet-based system solutions with unmatched efficiency and scalability.

Marking a Major Achievement: Successful Design of the First System Chiplet

The SSG team of expert engineers and designers, dedicated to pushing the boundaries of semiconductor technology, has reached an extraordinary milestone with the prototype design of the industry's first system chiplet. This innovative chiplet, featuring the Cadence Chiplet Architecture and Framework, was developed in collaboration with the Cadence Design Services teams. The chiplet showcases the integration of processors, system IP, and memory IP, enabling multiple chiplets within the same package, interconnected using the UCIe standard interface. This chiplet includes a system processor, a safety management processor, Cadence controllers and PHY IP for LPDDR5 and UCIe, and the Cadence Janus NoC technology. It also serves as a dynamic platform to demonstrate Cadence's latest UCIe IP, boasting up to 64GB/s peak bandwidth, and LPDDR5 IP, offering up to 32GB/s peak memory bandwidth. This innovation sets a new industry benchmark and paves the way for Cadence to help our customers achieve cutting-edge advancements.

Utilizing its mastery in advanced packaging and interconnect technologies, the SSG team develops scalable, high-performance technologies that empower customers to enhance efficiency and drive innovation.

The Importance of Chiplets

The industry is shifting from monolithic heterogeneous SoCs to chiplet-based products for several compelling reasons. Chiplet-based products enhance design and product factors, such as design/die reuse, contributing to engineering efficiency, faster platform refresh cadence, and the ability to optimize power, performance, and area (PPA) per chiplet. The rising cost of advanced process nodes raises the question of whether all components of an SoC product need to migrate to the latest node.

Chiplets offer a solution by enabling a multi-foundry business model and integrating cross-foundry process technologies within the same package. In addition, as technology density scaling slows in advanced nodes, designs are hitting Moore's law limits, requiring larger designs/chips with more functions and IP integrated into them, which are hitting process reticle limits. This shift is further supported by new packaging and interconnect solutions, such as advancements in 2.5D and 3D packaging and the standardization of Die2Die interfaces (e.g., UCIe). Chiplets are crucial for customers as they provide a transformative approach to addressing design challenges and accelerating time to market.
