Blog Review: Dec. 15


Arm's Hannah Peeler, Joshua Randall, and Zach Lasiuk examine the carbon cost of data centers and introduce a tool that allows users to make informed decisions about the carbon impact of their compute workloads. Synopsys' Kenneth Larsen provides a primer on the fundamentals of quantum computing, the role of photonics in building quantum systems, and the future potential impact on chip design.... » read more

The Return Of DAC In-Person


Apart from masked faces everywhere, you could be excused for not knowing that there was a pandemic going on. Sure, the numbers were down, the show floor was smaller, and most of the parties didn't happen, but everyone was so happy to be able to bump elbows with their colleagues. Buttons were available for attendees to show the level of comfort they had with various types of greetings, from "... » read more

Can Coherent Optics Reduce Data-Center Power?


As optical bandwidth requirements increase, system designers are turning to “coherent” modulation schemes that can place more data on the same laser light, and lower power over long connections. A newer question is whether those savings could be achieved for short connections within data centers, as well. “Coherent is the direction everything's moving, because for a given system and... » read more

Choose The Right Sensors For Autonomous Vehicles


When the world’s first “motorwagen” was introduced in 1885, the notion that a car would one day drive itself was laughable. Today, assisted and autonomous vehicles are the reality of an age where digital sensors can outperform human ability to perceive motion, distance, and speed. When used together, sensor technologies including camera, lidar, radar, and ultrasonic give vehicles one... » read more

Simulation Workflow For Efficiency Calculation Of A High-Performance Electric Powertrain


In battery electric vehicles the efficiency of the powertrain has a big impact on driving range and performance. As the overall efficiency of the electric powertrain is typically more than 90%, further optimization is challenging. Especially in high-performance electric vehicles, the efficiency over one or multiple laps on a racing track is crucial. It requires accurate estimation of power loss... » read more

Blog Review: Dec. 8


Arm's Shidhartha Das introduces a method to achieve fast yet accurate power modelling for both design and runtime power introspection within the same unified framework using machine learning and data science approaches. Synopsys' Mike Borza warns that the semiconductor industry is facing a flood of counterfeit chips and why being aware of different types of semiconductor scams and tackling t... » read more

Improving Energy And Power Efficiency In The Data Center


Energy costs in data centers are soaring as the amount of data being generated explodes, and it's being made worse by an imbalance between increasingly dense processing elements that are producing more heat and uneven server utilization, which requires more machines to be powered up and cooled. The challenge is to maximize utilization without sacrificing performance, and in the past that has... » read more

Week In Review: Design, Low Power


Infineon Technologies acquired Syntronixs Asia, which specializes in precision electroplating, a key process in the assembly process of semiconductors. Syntronixs Asia has a workforce of more than 500 people and has been a major service provider for Infineon since 2009. “Through this acquisition, we have made another important step to strengthen the resilience of our supply chain,” said Tho... » read more

Advanced Packaging For Automotive Chips


Multiple types of chips may be better than one for dealing with large amounts and different types of data, but in automotive applications it's not entirely clear how or even whether they should be packaged together. The biggest problem with electronics in vehicles is the extreme range of temperatures, both within and outside of vehicles. Without adequate cooling, chips can age prematurely, s... » read more

Blog Review: Dec. 1


Synopsys' Mike Gianfagna points to three events that created a fundamental shift in product development that has enabled rapid introduction of a wide range of new products. Siemens' Sagi Reuven considers some key challenges facing the supply chain and the impact on electronics manufacturers, from rising shipping costs to shortages of raw materials and transportation labor. Cadence's Frank... » read more
