HBM3E: All About Bandwidth


The rapid rise in size and sophistication of AI/ML training models requires increasingly powerful hardware deployed in the data center and at the network edge. This growth in complexity and data stresses the existing infrastructure, driving the need for new and innovative processor architectures and associated memory subsystems. For example, even GPT-3 at 175 billion parameters is stressing the... » read more

Power Delivery Challenged By Data Center Architectures


Processor and data center architectures are changing in response to the higher voltage needs of servers running AI and large language models (LLMs). At one time, servers drew a few hundred watts for operation. But over the past few decades that has changed drastically due to a massive increase in the amount of data that needs to be processed and user demands to do it more quickly. NVIDIA's G... » read more

Voltage Drop Now Requires Dynamic Analysis


At one time a relatively infrequent occurrence, voltage drop is now a major impediment to reliability at advanced nodes. Decades ago, voltage drop was only an issue for very large and high-speed designs, where there was concern about supply lines delivering full voltage to transistors. As design margins have tightened in modern advanced designs, controlling voltage drop has become a requiremen... » read more

Powering The Future Of Flight: Designing A Hydrogen-Powered eVTOL


A large, bustling city surrounds you — crowded streets and tall buildings reaching toward the sky. You’re late for an appointment. However, instead of hopping into a car, you look above for your ride: an electric vertical takeoff and landing (eVTOL) vehicle. It is a small aircraft that takes off and lands vertically like helicopters, uses sustainable electric propulsion systems, and is inte... » read more

Blog Review: Aug. 7


Synopsys' Jyotika Athavale and Randy Fish investigate the problem of silent data corruption caused by difficult-to-detect hardware defects that cause unnoticed errors in the data being processed and is becoming an increasingly pressing problem as computing scales massively at a rapid pace with the demands of AI. Siemens' Keith Felton suggests adopting physical design reuse circuits to provid... » read more

A Software-First Mindset for Driving Efficiency and Sustainability for Industrial IoT


Schneider Electric, Arm, and system integrators Witekio and Capgemini have produced a software-defined platform for industrial automation and energy management. The platform uses cloud-native techniques to create a flexible, energy-efficient reference design that uses virtualization to enable real-time, mixed-criticality services at the embedded edge.

Focus Shifts To Application-Specific Workloads


Experts At The Table: EDA has undergone numerous workflow changes over time. Different skill sets have come into play over the years, and at times this changed the definition of what it means to design at the system level. To work out what this means for designers today, and how it looks going forward, Semiconductor Engineering sat down with Michal Siwinski, chief marketing officer at Arteris; ... » read more

Bluetooth’s New Era: The Role Of Channel Sounding And Adaptable Testing Solutions


By Jake Harnack and Alejandro Escobar Calderon Bluetooth technology has experienced a remarkable transformation since its inception, evolving from a basic tool for data transfer to a near-ubiquitous wireless technology used for audio streaming, location services, and smart-home networks. As sales of Bluetooth-enabled devices nears 5 billion units per year in 2024, the Bluetooth standard is e... » read more

Joint Interdisciplinary Work To Enable Novel, Industry-Ready Chiplet Solutions


Fraunhofer is going to establish the Chiplet Center of Excellence (CCoE), which is a unique research activity based on Fraunhofer‘s long experience and broad research portfolio in design, implementation and test of 2.5 and 3D integrated electronic systems. The Center aims at establishing a common understanding among the partners and at creating a suitable chiplet development methodology. This... » read more

Decoding Glitch Power at the RTL Stage


In the context of analyzing digital semiconductor circuits, a glitch is any unwanted or unused signal transition, or toggle. A glitch is often a transient signal that is much shorter than a clock period and therefore is not captured by the next register stage. We also encounter full transition glitches, or transport glitches, which refer to toggles in a data path circuit that cover a full clock... » read more
