Ansys’ Vidyu Challa checks out how to identify the most important battery metrics for a particular application and trade these off against others with a focus on the important considerations when selecting the right battery for a consumer application, such as rechargeability, energy density, power density, shelf life, safety, form factor, cost, and flexibility.

Cadence’s Shyam Sharma points to the Training Modes supported by the latest DRAMs that assist with handshaking for high speed I/O and what system designers ought to consider for systems to work as intended, including ensuring initiator and target are able to communicate with each other.

Synopsys’ Emilie Viasnoff examines how AR/VR is driving innovation in imaging design and why the same level of effort that goes into packing incredible amounts of compute performance into smartphones must be deployed by optics-electronics community to enable miniaturized, digital, and smart imaging systems.

Siemens’ Adrian Perregaux and Jonathan Melvin find that to significantly reduce global electricity use, increasing the efficiency of electric motors is key and that electromagnetic simulation can help in the design of more efficient motors.

Arm’s Chris Bergey argues that the core elements of computing need to be rethought to combat increasing energy consumption and associated carbon emissions and calls for new processor designs, new server architectures, and other disruptive approaches.

Coventor’s Jeonghoon Kim looks at how building and sharing sets of process libraries not only increases the process expertise available within a company but also leads to more accurate process modeling and faster time to market.

Codasip’s Philippe Luc suggests taking a ‘Swiss cheese model’ approach to processor verification by layering many different verification techniques to create a redundancy that has a higher chance of catching bugs than any one strategy alone.

Lam Research’s David Haynes checks out how 5G and Wi-Fi 6/6E can work together to create a seamless, integrated wireless experience by handing off mobile data from 5G networks to Wi-Fi as people move through daily environments.

SEMI’s Inna Skvortsova considers how the digital transformation of global economies led to 2021 marking a second consecutive year of record growth for the semiconductor industry despite the turbulence brought by COVID-19, geopolitical tensions, and supply-chain constraints.

Nvidia’s Arash Vahdat and Karsten Kreis explain how generative adversarial networks are used to synthesize novel data and images based on real data, the three key requirements of generative models that are difficult to satisfy simultaneously, and a class called diffusion models that show promise for high sample quality and mode coverage.

Memory analyst Jim Handy examines the chip shortage’s impact on pricing trends and how it interacts with memory demand, growth, and availability.
