On-Package Memory With UCIe To Improve Bandwidth Density And Power Efficiency (AMD, Intel Corp.)


A new technical paper titled "On-Package Memory with Universal Chiplet Interconnect Express (UCIe): A Low Power, High Bandwidth, Low Latency and Low Cost Approach" was published by researchers at Intel Corporation and AMD. Abstract "Emerging computing applications such as Artificial Intelligence (AI) are facing a memory wall with existing on-package memory solutions that are unable to meet ... » read more

The Future Of SoC Design Is Data Movement


The semiconductor industry is experiencing rapid advances in chiplet adoption, high-bandwidth memory, Compute Express Link (CXL) fabrics, and automotive zonal architectures. As we move into the second half of 2025, the only sustainable path forward is a layered, physically aware, and automated interconnect methodology that can keep pace with escalating complexity. This article is Part Two of... » read more

From Discovery To High-Speed Delivery: A Unified Verification Approach For UCIe 3.0 Features And Manageability


By Ujjwal Negi and Prashant Dixit The Universal Chiplet Interconnect Express (UCIe) standard is redefining multi-die integration, enabling high-performance, scalable connections between heterogeneous chiplets. UCIe 2.0 introduced a dedicated manageability layer — a control plane for configuring, monitoring, and coordinating chiplet management elements independently from mainband and sideba... » read more

Verifying The Evolving UCIe Landscape


This paper details a verification strategy for UCIe 3.0 designs, integrating both legacy manageability architecture and emerging UCIe 3.0 features into a reusable, scalable framework. Built on a layered UVM architecture, Questa One Avery VIP for UCIe enables flexible modeling of complex domains through configurable APIs and supports automated discovery and routing table setup for both direct an... » read more

Chiplet Design Considerations


Chiplets are a way to offer continuing increases in compute capacity and I/O bandwidth needs by splitting SoC functionality into smaller heterogeneous or homogeneous dies called chiplets and integrating these chiplets into a single system in package (SIP), where the total silicon content can exceed the reticle size of a single SoC. SIP includes traditional package substrates but also may includ... » read more

Chiplet Interfaces Embrace Failures


Redundancy in chiplet interfaces is now a prerequisite for achieving sufficient yield in high-performance computing devices, which today are packed with tens of thousands of interconnects. And as the number and density of those interconnects increases, the prospects for yield only worsen. For more than two decades, high-speed I/O interfaces have included reliability strategies to manage in-f... » read more

When Standards Enable Chiplets


Semiconductor Engineering sat down and discussed the need for standards to enable an ecosystem for chiplets with Mark Kuemerle, vice president of technology for Marvell; Letizia Giuliano, vice president for product marketing and management at Alphawave Semi; Hee-Soo Lee, HSD segment lead for Keysight; Mick Posner, senior product group director for Cadence’s Compute Solutions Group; and Rob Kr... » read more

Do We Have Enough Standards For An Open-Chiplet Ecosystem?


For some time now, the semiconductor industry has been discussing the development of an open chiplet ecosystem. The idea is that, rather than having monolithic systems on a chip, it should be possible to combine smaller, specialized chiplets in a modular way – ideally across different manufacturers. Doing so would promise great flexibility with much shorter development times, resulting in muc... » read more

When Can I Buy A Chiplet?


One year ago, Semiconductor Engineering conducted its first roundtable to find out the true state of the industry for chiplets. At that event, it was stated that no chiplet had ever been reused in a design for which it was not initially intended. How much has changed over the past year? Returning from last year were Mark Kuemerle, vice president of technology for Marvell; Letizia Giuliano, vice... » read more
