PCB Layout Tips For Low Side Gate Drivers With OCP
By Weidong Chu - 10 Mar, 2022 - Comments: 0

Our 1ED44173/5/6 are the new low side gate driver ICs that integrate over-current protection (OCP), FAULT status output and enable function. This high integration level is excellent for the digitally controlled Power Factor Correction (PFC) applications with boost topology and ground reference switching. In PFC applications, shunts are used to sense power switch current or DC bus current... » read more

Constraints On The Electricity Grid
By Paul McLellan - 10 Mar, 2022 - Comments: 3

I recently wrote about Moss Landing, the biggest grid battery storage operation in the world. I discovered from talking to a friend recently that most people have no idea what constraints the electricity grid operates under. I think most politicians are the same, and they assume that if we build enough windmills and solar panels then we can live in some sort of eco-nirvana. But that's not goin... » read more

Comparing Formal And Simulation Code Coverage
By Siemens EDA - 09 Mar, 2022 - Comments: 0

There is a difference in semantics between code coverage generated from a simulator engine and code coverage generated from a formal engine. This paper seeks to raise the awareness of verification engineers on how best to make use of the code coverage data generated by different verification engines. The paper lays out the reasons for using code coverage and describes how simulation code covera... » read more

Advancing Electric Vehicle Battery Characterization By Integrating Drive Cycle On Cooling Impacts
By Ansys - 09 Mar, 2022 - Comments: 0

Battery powered electric vehicles (EVs) and hybrid electric vehicles (HEVs) have been gaining market share as the public’s environmental concerns drive the demand for better fuel efficiency. Apart from the need to improve the mileage one can drive before recharging, battery reliability is another major concern. Effective cooling in intense charge/discharge conditions is crucial to minimizi... » read more

Navigating The Intersection Of Safety And Security
By Siemens EDA - 09 Mar, 2022 - Comments: 0

Vehicle systems and the semiconductors used within them are some of the most complex electronics seen today. In the past, electronics going into vehicle systems implemented flat architectures with isolated functions controlling various components of the power train and vehicle dynamics. However, to support the realization of Level 4 and Level 5 (L4/L5) autonomous driving, a massive restructure ... » read more

A Framework For Ultra Low-Power Hardware Accelerators Using NNs For Embedded Time Series Classification
By Fraunhofer IIS/EAS - 09 Mar, 2022 - Comments: 0

In embedded applications that use neural networks (NNs) for classification tasks, it is important to not only minimize the power consumption of the NN calculation, but of the whole system. Optimization approaches for individual parts exist, such as quantization of the NN or analog calculation of arithmetic operations. However, there is no holistic approach for a complete embedded system design ... » read more

Research Bits: March 7
By Jesse Allen - 07 Mar, 2022 - Comments: 0

Optical signal processing with acoustic waves Researchers from Pohang University of Science & Technology (POSTECH) demonstrated an optical-wave signal that can be amplified or canceled using optically driven acoustic waves on a silicon chip. Optical signal processing using Brillouin scattering, in which acoustic waves scatter light, has been demonstrated in nanophotonic structures. But ... » read more

The Ethernet Evolution
By Ed Sperling - 01 Mar, 2022 - Comments: 0

Ethernet was expected to be long gone by now, but predictions of its demise were decades premature. John Swanson, senior product marketing manager for high-performance computing digital IP at Synopsys, talks about how Ethernet has evolved over the past 45 or so years from a somewhat “boring” technology to one that is at the forefront of data center performance improvements, with more update... » read more

Research Bits: March 1
By Jesse Allen - 01 Mar, 2022 - Comments: 0

Large-scale phased array Researchers at Princeton University developed a large-scale high-frequency antenna array using thin-film materials. “To achieve these large dimensions, people have tried discrete integration of hundreds of little microchips. But that’s not practical — it’s not low-cost, it’s not reliable, it’s not scalable on a wireless systems level,” said senior stud... » read more

Fuzz Testing Software-Defined Vehicles Using Agent Instrumentation
By Synopsys - 23 Feb, 2022 - Comments: 0

Cybersecurity has become intertwined into each step of the automotive development process. In particular, fuzz testing has proven to be a powerful approach to detect unknown vulnerabilities in automotive systems. But with limited instrumentation, especially on software-heavy systems such as high-performance computers (HPCs), several types of issues go undetected, including memory leaks and case... » read more
