State-Space Model Of An Electro-Mechanical-Acoustic Contactless Energy Transfer System Based On Multiphysics Networks
By Fraunhofer IIS/EAS - 11 May, 2022 - Comments: 0

Contactless energy transfer systems are mainly divided into acoustic, inductive, capacitive and optical, in which main applications are related to biomedical, wireless chargers and sensors in metal enclosures. When solids are used as transfer media, ultrasound transducers based on piezoelectricity can be used for through-wall power transfer, which can be named as electro-mechanical-acoustic con... » read more

The Challenges Of Incremental Verification
By Brian Bailey - 28 Apr, 2022 - Comments: 1

Verification consumes more time and resources than design, and yet little headway is being made to optimize it. The reasons are complex, and there are more questions than there are answers. For example, what is the minimum verification required to gain confidence in a design change? How can you minimize the cost of finding out that the change was bad, or that it had unintended consequences? ... » read more

More Options, Less Dark Silicon
By Ed Sperling - 20 Apr, 2022 - Comments: 0

Chipmakers are beginning to re-examine how much dark silicon should be used in a heterogenous system, where it works best, and what alternatives are available — a direct result of a slowdown in Moore's Law scaling and the increasing disaggregation of SoCs. The concept of dark silicon has been around for a couple decades, but it really began taking off with the introduction of the Internet ... » read more

How Do I Come To Trust An Electronic Component?
By Roland Jancke - 14 Apr, 2022 - Comments: 0

Can I trust all of the electronic systems in my vehicle, for example if I’m driving my car at a high speed on the highway or in city traffic at a confusing intersection? Will all of the vehicle’s sensors work as they should and correctly recognize all of the possible dangers around me? In modern vehicles and complex industrial plants today, a number of sensors and many electronic compone... » read more

Always-On, Ultra-Low-Power Design Gains Traction
By Ann Mutschler - 14 Apr, 2022 - Comments: 0

A surge of electronic devices powered by batteries, combined with ever-increasing demand for more features, intelligence, and performance, is putting a premium on chip designs that require much lower power. This is especially true for always-on circuits, which are being added into AR/VR, automotive applications with over-the-air updates, security cameras, drones, and robotics. Also known as ... » read more

Battery Management Getting Competitive For EVs
By Ed Sperling - 07 Apr, 2022 - Comments: 0

The success or failure of future electric vehicles will depend on where and how those cars are used, as well as significant advances in battery materials, energy density, and some very complex battery management systems. Battery power needs to be balanced, stored for extended times, and delivered to wherever it is needed most in real time. This is a huge challenge, and nearly everything in a... » read more

Incremental Design Breakdown
By Brian Bailey - 24 Mar, 2022 - Comments: 0

For the past two decades, most designs have been incremental in nature. They heavily leveraged IP used in previous designs, and that IP often was developed by third parties. But there are growing problems with that methodology, especially at advanced nodes where back-end issues and the impact of 'shift left' are reducing the savings from reuse. The value of IP reuse has been well established... » read more

How To Justify A Data Center
By Ann Mutschler - 24 Mar, 2022 - Comments: 0

The breadth of cloud capabilities and improvements in cost and licensing structures is prompting chipmakers to consider offloading at least some of their design work into the cloud. Cloud is a viable business today for semiconductor design. Over the past decade, the interest in moving to cloud computing has grown from an idea that was fun to talk about — but which no one was serious about ... » read more

Virtual Testing Of Automotive Sensor Systems
By Christoph Sohrmann - 10 Mar, 2022 - Comments: 0

The development of vehicles has always been a discipline of mechanical engineering. After all, cars were always about the engine, the power, the efficiency. Traditionally, the development of the complex overall automotive system has always been carried out in accordance with classical principles of mechanical engineering, for example by using development models like the V-model. Although the pr... » read more

Why Comparing Processors Is So Difficult
By Brian Bailey - 10 Mar, 2022 - Comments: 2

Every new processor claims to be the fastest, the cheapest, or the most power frugal, but how those claims are measured and the supporting information can range from very useful to irrelevant. The chip industry is struggling far more than in the past to provide informative metrics. Twenty years ago, it was relatively easy to measure processor performance. It was a combination of the rate at ... » read more
