Synopsys, Inc. today announced it is extending its collaboration with TSMC to advance multi-die system designs with a comprehensive solution supporting the latest 3Dblox 2.0 standard and TSMC's 3DFabric technologies. The Synopsys Multi-Die System solution includes 3DIC Compiler, a unified exploration-to-signoff platform that delivers the highest levels of design efficiency for capacity and performance. In addition, Synopsys has achieved first-pass silicon success of its Universal Chiplet Interconnect Express (UCIe) IP on TSMC's leading N3E process for seamless die-to-die connectivity.

"TSMC has been working closely with Synopsys to deliver differentiated solutions that address designers' most complex challenges from early architecture to manufacturing," said Dan Kochpatcharin, head of the Design Infrastructure Management Division at TSMC. "Our long history of collaboration with Synopsys benefits our mutual customers with optimized solutions for performance and power efficiency to help them address multi-die system design requirements for high-performance computing, data center, and automotive applications."

Today, the UCIe Consortium announced the public release of UCIe (Universal Chiplet Interconnect Express ) 1.1 Specification to deliver valuable improvements in the chiplet ecosystem, extending reliability mechanisms to more protocols and supporting broader usage models. Additional enhancements are included for automotive usages - such as predictive failure analysis and health monitoring - and enabling lower-cost packaging implementations. The specification also details architectural specification attributes to define system setups and registers that will be used in test plans and compliance testing to ensure device interoperability. The UCIe 1.1 Specification is fully backward compatible with the UCIe 1.0 Specification.

"UCIe Consortium is living up to its mission and establishing a vibrant chiplet ecosystem as the industry musters around UCIe technology," said Dr. Debendra Das Sharma, chairman, UCIe Consortium. "The UCIe 1.1 Specification was developed by leaders in the industry to advance the chiplet ecosystem and address significant demand for full stack streaming protocol enhancements. We're proud of the progress this release represents toward realizing our vision and our underlying efforts to establish a chiplet ecosystem by developing a robust compliance program."

Accelerating the integration of heterogeneous dies to enable the next level of system scalability and functionality, Synopsys, Inc. (Nasdaq: SNPS) has strengthened its collaboration with TSMC and Ansys for multi-die system design and manufacturing. Synopsys provides the industry's most comprehensive EDA and IP solutions for multi-die systems on TSMC's advanced 7 nm, 5 nm and 3 nm process technologies with support for TSMC 3DFabric technologies and 3Dblox standard. The integration of Synopsys implementation and signoff solutions and Ansys multi-physics analysis technology on TSMC processes allows designers to tackle the biggest challenges of multi-die systems, from early exploration to architecture design with signoff power, signal and thermal integrity analysis.

"Multi-die systems provide a way forward to achieve reduced power and area and higher performance, opening the door to a new era of innovation at the system-level," said Dan Kochpatcharin, head of Design Infrastructure Management Division at TSMC. "Our long-standing collaboration with Open Innovation Platform (OIP) ecosystem partners like Synopsys and Ansys gives mutual customers a faster path to multi-die system success through a full spectrum of best-in-class EDA and IP solutions optimized for our most advanced technologies."

Tachyum announced today it has strengthened its presence in the Universal Chiplet Interconnect Express (UCIe) organization that develops and supports the chiplet ecosystem and in-package innovations. The UCIe community fosters collaboration among leaders in semiconductors, packaging, IP suppliers, foundries, and cloud services.

UCIe 1.0 is an open specification guiding the interconnection between chiplets within a package to ensure communication and functionality. Chiplet-based design increases density and capability compared to standard printed circuit-boards (PCBs), and enables much smaller, lower-cost solutions that consume less power. UCIe specification addresses the die-to-die I/O physical layer, die-to-die protocols, and software stack currently served by PCI Express (PCIe) and Compute Express Link (CXL) industry standards. UCIe ultimately extends the PCIe standard to in-package interconnects and allows the potential to bring CXL into in-package integration.

Winbond has joined the UCIe (Universal Chiplet Interconnect Express) Consortium, the industry Consortium dedicated to advancing UCIe technology. This open industry standard defines interconnect between chiplets within a package, enabling an open chiplet ecosystem and facilitating the development of advanced 2.5D/3D devices.

A leader in high-performance memory ICs, Winbond is an established supplier of known good die (KGD) needed to assure end-of-line yield in 2.5D/3D assembly. 2.5D/3D multichip devices are needed to realize the exponential improvements in performance, power efficiency, and miniaturization, demanded by the explosion of technologies such as 5G, Automotive, and Artificial Intelligence (AI).

Eliyan Corporation, credited for the invention of the semiconductor industry's highest-performance and most efficient chiplet interconnect, today announced two major milestones in the commercialization of its technology for multi-die chiplet integration: the close of its Series A $40M funding round, and the successful tapeout of its technology on an industry standard 5-nanometer (nm) process.

Eliyan's NuLink PHY and NuGear technologies address the critical need for a commercially viable approach to enabling high performance and cost-effectiveness in the connection of homogeneous and heterogenous architectures on a standard, organic chip substrate. It has proven to achieve similar bandwidth, power efficiency, and latency as die-to-die implementations using advanced packaging technologies, but without the other drawbacks of specialized approaches.

Enabling a new generation of system-level integration in data centers, NVIDIA today announced NVIDIA NVLink -C2C, an ultra-fast chip-to-chip and die-to-die interconnect that will allow custom dies to coherently interconnect to the company's GPUs, CPUs, DPUs, NICs and SOCs. With advanced packaging, NVIDIA NVLink-C2C interconnect would deliver up to 25x more energy efficiency and be 90x more area-efficient than PCIe Gen 5 on NVIDIA chips and enable coherent interconnect bandwidth of 900 gigabytes per second or higher.

"Chiplets and heterogeneous computing are necessary to counter the slowing of Moore's law," said Ian Buck, vice president of Hyperscale Computing at NVIDIA. "We've used our world-class expertise in high-speed interconnects to build uniform, open technology that will help our GPUs, DPUs, NICs, CPUs and SoCs create a new class of integrated products built via chiplets."

Intel, along with Advanced Semiconductor Engineering Inc. (ASE), AMD, Arm, Google Cloud, Meta, Microsoft Corp., Qualcomm Inc., Samsung and Taiwan Semiconductor Manufacturing Co., have announced the establishment of an industry consortium to promote an open die-to-die interconnect standard called Universal Chiplet Interconnect Express (UCIe). Building on its work on the open Advanced Interface Bus (AIB), Intel developed the UCIe standard and donated it to the group of founding members as an open specification that defines the interconnect between chiplets within a package, enabling an open chiplet ecosystem and ubiquitous interconnect at the package level.

"Integrating multiple chiplets in a package to deliver product innovation across market segments is the future of the semiconductor industry and a pillar of Intel's IDM 2.0 strategy," said Sandra Rivera, executive vice president and general manager of the Datacenter and Artificial Intelligence Group at Intel. "Critical to this future is an open chiplet ecosystem with key industry partners working together under the UCIe Consortium toward a common goal of transforming the way the industry delivers new products and continues to deliver on the promise of Moore's Law."
