Chiplet Interconnects Add Power And Signal Integrity Issues


The flexibility and scalability offered by chiplets make them an increasingly attractive choice over planar SoCs, but the rollout of increasingly heterogeneous assemblies adds a variety of new challenges around the processing and movement of data. Nearly all of the chiplets in use today were designed in-house by large systems companies and IDMs. Going forward, third-party chiplets will begin... » read more

Top-Down Vs. Bottom-Up Chiplet Design


Chiplets are gaining widespread attention across the semiconductor industry, but for this approach to really take off commercially it will require more standards, better modeling technologies and methodologies, and a hefty amount of investment and experimentation. The case for chiplets is well understood. They can speed up time to market with consistent results, at whatever process node work... » read more

How AI Is Transforming System Design


Experts At The Table: ChatGPT and other LLMs have attracted most of the attention in recent years, but other forms of AI have long been incorporated into design workflows. The technology has become so common that many designers may not even realize it’s a part of the tools they use every day. But its adoption is spreading deeper into tools and methodologies. Semiconductor Engineering sat down... » read more

Chip Industry Week In Review


SK hynix started mass production of 1-terabit  321-high NAND, with availability scheduled for the first half of next year. Rapidus will receive an additional ¥200 billion yen ($1.28B) from the Japanese government beginning in fiscal year 2025, reports Nikkei. This is on top of ¥920 billion yen ($5.98B) Rapidus has already received from the government in support of its goal to reach commer... » read more

Chiplets Make Progress Using Interconnects As Glue


Breaking up SoCs into their component parts and putting those and other pieces together in some type of heterogeneous assembly is beginning to take shape, fueled by advances in interconnects, complex partitioning, and industry learnings about what works and what doesn't. While the vision of plug-and-play remains intact, getting there is a lot more complicated than initially imagined. It can ... » read more

UMI: Extending Chiplet Interconnect Standards To Deal With The Memory Wall


With the Open Compute Project (OCP) Summit upon us, it’s an appropriate time to talk about chiplet interconnect (in fact the 2024 OCP Summit has a whole day dedicated to the multi-die topic, on October 17). Of particular interest is the Bunch of Wires (BoW) interconnect specification that continues to evolve. At OCP there will be an update and working group looking at version 2.1 of BoW. (... » read more

Chip Industry Week In Review


Imec announced a new automotive chiplet consortium to evaluate which different architectures and packaging technologies are best for automotive applications. Initial members includes Arm, ASE, Cadence, Siemens, Synopsys, Bosch, BMW, Tenstorrent, Valeo, and SiliconAuto. Imec also launched star, a global network bringing together automotive and semiconductor innovators to address technological c... » read more

Partitioning In The Chiplet Era


The widespread adoption of chiplets in domain-specific applications is creating a partitioning challenge that is much more complex than anything chip design teams have dealt with in previous designs. Nearly all the major systems companies, packaging houses, IDMs, and foundries have focused on chiplets as the best path forward to improve performance and reduce power. Signal paths can be short... » read more

Using AI To Glue Disparate IC Ecosystem Data


AI holds the potential to change how companies interact throughout the global semiconductor ecosystem, gluing together different data types and processes that can be shared between companies that in the past had little or no direct connections. Chipmakers always have used abstraction layers to see the bigger picture of how the various components of a chip go together, allowing them to pinpoi... » read more

UMI Can Scale the Memory Wall


While the improvements in processor performance to enable the incredible compute requirements of applications like Chat-GPT get all the headlines, a not-so-new phenomenon known as the memory wall risks negating those advancements. Indeed, it has been clearly demonstrated that as CPU/GPU performance increases, wait time for memory also increases, preventing full utilization of the processors. ... » read more
