More Data, More Redundant Interconnects


The proliferation of AI dramatically increases the amount of data that needs to be processed, stored, and moved, accelerating the aging of signal paths through which that data travels and forcing chipmakers to build more redundancy into the interconnects. In the past, nearly all redundant data paths were contained within a planar chip using a relatively thick silicon substrate. But as chipma... » read more

Die-to-die Interconnect Standards In Flux


UCIe, a standard for die-to-die interconnect in advanced packages, has drawn concern about being too heavyweight with its 2.0 release. But the fact that many of the new features are optional seems to have been lost in much of the public discussion. In fact, new capabilities that support a possible future chiplet marketplace are not required for designs that don’t target that marketplace. ... » read more

Speeding Up Die-To-Die Interconnectivity


Disaggregating SoCs, coupled with the need to process more data faster, is forcing engineering teams to rethink the electronic plumbing in a system. Wires don't shrink, and just cramming more wires or thicker wires into a package are not viable solutions. Kevin Donnelly, vice president of strategic marketing at Eliyan, talks about how to speed up data movement between chiplets with bi-direction... » read more

AI Drives Re-Engineering Of Nearly Everything In Chips


AI's ability to mine patterns across massive quantities of data is causing fundamental changes in how chips are used, how they are designed, and how they are packaged and built. These shifts are especially apparent in high-performance AI architectures being used inside of large data centers, where chiplets are being deployed to process, move, and store massive amounts of data. But they also ... » read more

Challenges In Managing Chiplet Resources


Managing chiplet resources is emerging as a significant and multi-faceted challenge as chiplets expand beyond the proprietary designs of large chipmakers and interact with other elements in a package or system. Poor resource management in chiplets adds an entirely new dimension to the usual power, performance, and area tradeoffs. It can lead to performance bottlenecks, because as chiplets co... » read more

3D-IC For The Masses


The concepts of 3D-IC and chiplets have the whole industry excited. It potentially marks the next stage in the evolution of the IP industry, but so far, technical difficulties and cost have curtailed its usage to just a handful of companies. Even within those, they do not appear to be seeing benefits from heterogeneous integration or reuse. Attempts to make this happen are not new. "A decade... » read more

Chiplets Add New Power Issues


Delivering and managing power are becoming key challenges in the rollout of chiplets, adding significantly to design complexity and forcing chipmakers to weigh tradeoffs that can have a big impact on the performance, reliability, and the overall cost of semiconductors. Power is a concern for every chip and chiplet design, even if the specifics differ based on the application. Systems vendors... » read more

Lines Blurring Between Supercomputing And HPC


Supercomputers and high-performance computers are becoming increasingly difficult to differentiate due to the proliferation of AI, which is driving huge performance increases in commercial and scientific applications and raising similar challenges for both. While the goals of supercomputing and high-performance computing (HPC) have always been similar — blazing fast processing — the mark... » read more

What Scares Chip Engineers About Generative AI


Experts At The Table: LLMs and other generative AI programs are a long way away from being able to design entire chips on their own from scratch, but the emergence of the tech has still raised some genuine concerns. Semiconductor Engineering sat down with a panel of experts, which included Rod Metcalfe, product management group director at Cadence; Syrus Ziai, vice-president of engineering at E... » read more

Cracking The Memory Wall


Processor performance continues to improve exponentially, with more processor cores, parallel instructions, and specialized processing elements, but it is far outpacing improvements in bandwidth and memory. That gap, the so-called memory wall, has persisted throughout most of this century, but now it is becoming more pronounced. SRAM scaling is slowing at advanced nodes, which means SRAM takes ... » read more
