Is UCIe Really Universal?

By Brian Bailey - 22 Nov, 2022 - Comments: 3

Chiplets are rapidly becoming the means to overcome the slowing of Moore's Law, but whether one interface is capable of joining them all together isn't clear yet. The Universal Chiplet Interconnect Express (UCIe) believes it will work, but some in the industry remain unconvinced. At least part of the problem is that interconnect standards are never truly finished. Even today, the protocols tha... » read more

Week In Review: Design, Low Power

By Jesse Allen - 11 Nov, 2022 - Comments: 0

Chip design Fraunhofer IIS/EAS implemented the Bunch of Wires (BoW) standard-based interface IP from the Open Compute Project (OCP) on Samsung's 5nm technology. The effort is intended to make chiplets more feasible for products with small and medium-sized production runs and determine the need for additional uniform standards in the future, such as for die-to-die bonding. “As part of t... » read more

Raising IP Integration Up A Level

By Brian Bailey - 27 Oct, 2022 - Comments: 0

An increase in the number and complexity of IP blocks, coupled with changing architectures and design concerns, are driving up the need for new tools that can enable, automate, and optimize integration in advanced chips and packages. Power, security, verification and a host of other issues are cross-cutting concerns, and they make pure hierarchical approaches difficult. Adding to future comp... » read more

HBM3 In The Data Center

By Ed Sperling - 17 Oct, 2022 - Comments: 0

Frank Ferro, senior director of product management at Rambus, talks about the forthcoming HBM3 standard, why this is so essential for AI chips and where the bottlenecks are today, what kinds of challenges are involved in working with this memory, and what impact chiplets and near-memory compute will have on HBM and bandwidth. » read more

Week In Review: Manufacturing, Test

By Karen Heyman - 29 Jul, 2022 - Comments: 1

The U.S. Congress approved the CHIPS Act, a mammoth bipartisan achievement the New York Times called “the most significant government intervention in industrial policy in decades.” As passed, the full package — now called the Chips and Science Act — contains $52 billion in direct assistance for the semiconductor industry, along with $24 billion in tax incentives. In addition, the bill c... » read more

Chiplets: Current Status

By Andy Heinig - 12 May, 2022 - Comments: 0

Recent weeks have seen a number of interesting developments in the area of chiplets. An increasing number of products based on chiplets have been brought to market, especially in the processors segment. For example, Apple and AMD now have processors with chiplets on the market and under production in high volumes. On one hand, this means that sufficient production capacity has now been built up... » read more

Clocks Getting Skewed Up

By Brian Bailey - 30 Mar, 2022 - Comments: 0

At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it's fraught with the most problems at the physical level. To some, the clock is the AC power supply of the chip. To others, it is an analog network almost beyond analysis. Ironically, there are no languages to describe clocking, few tools t... » read more

Missing Interposer Abstractions And Standards

By Brian Bailey - 29 Nov, 2021 - Comments: 0

The design and analysis of an SoC based on an interposer is not for the faint of heart today, but the industry is aware of the challenges and is attempting to solve them. Until that happens, however, it will be a technique that only large companies can deploy because they need to treat everything almost as if it were a single die. The construction of large systems uses techniques, such as ab... » read more

Waiting For Chiplet Standards

By Brian Bailey - 25 Mar, 2021 - Comments: 2

The need and desire for chiplets is increasing, but for most companies that shift will happen slowly until proven standards are in place. Interoperability and compatibility depend on many layers and segments of the supply chain coming to agreement. Unfortunately, fragmented industry requirements may lead to a plethora of solutions. Standards always have enabled increasing specialization. ... » read more
