The High But Often Unnecessary Cost Of Coherence


Cache coherency, a common technique for improving performance in chips, is becoming less useful as general-purpose processors are supplemented with, and sometimes supplanted by, highly specialized accelerators and other processing elements. While cache coherency won't disappear anytime soon, it is increasingly being viewed as a luxury necessary to preserve a long-standing programming paradig... » read more

Effectively Addressing The Challenge Of Securing Connected And Autonomous Vehicles


Vehicles are becoming the most sophisticated connected objects in the ‘Internet of Things’. As vehicles integrate functionality that will enable a fully autonomous future, the attack surface grows substantially. Combined with remote connectivity at multiple points, the clock is ticking in a race to improve cybersecurity in all types of vehicles to ensure that all stakeholders, but particula... » read more

What’s Missing For Designing Chips At The System Level


Semiconductor Engineering sat down to talk about design challenges in advanced packages and nodes with John Lee, vice president and general manager for semiconductors at Ansys; Shankar Krishnamoorthy, general manager of Synopsys' Design Group; Simon Burke, distinguished engineer at Xilinx; and Andrew Kahng, professor of CSE and ECE at UC San Diego. This discussion was held at the Ansys IDEAS co... » read more

New Approaches For Processor Architectures


Processor vendors are starting to emphasize microarchitectural improvements and data movement over process node scaling, setting the stage for much bigger performance gains in devices that narrowly target what end users are trying to accomplish. The changes are a recognition that domain specificity, and the ability to adjust or adapt designs to unique workloads, are now the best way to impro... » read more

Making Lidar More Useful


Lidar, one of a trio of “vision” technologies slated for cars of the future, is improving both in terms of form and function. Willard Tu, director of automotive at Xilinx, talks with Semiconductor Engineering about different approaches and tradeoffs between cost, compute intensity and resolution, various range and field of view options, and why convolutional neural networks are so important... » read more

The Case For FPGAs In Cars


Field-programmable gate arrays (FPGAs) thrive in rapidly evolving new markets before being replaced by hard-wired ASICs, but in automotive that crossover is likely to happen significantly later than in the past. Historically, FPGAs have held temporary positions until volumes increased enough to cost-reduce the FPGAs out in favor of a hardened version. With automobiles, there are so many chan... » read more

The Good And Bad Of Auto IC Updates


Keeping automobiles updated enough to avoid problems is becoming increasingly difficult as more complex electronics are added into vehicles, and as the lifetimes of those devices are extended to a decade or more. Modern vehicles are full of electronics. In fact, the value of electronic devices used in modern vehicles is expected to double in the next 10 years, growing to $469 billion by 2030... » read more

Continuing Challenges For Open-Source Verification


Experts at the Table: This is the last part of the series of articles derived from the DVCon panel that discussed Verification in the Era of Open Source. It takes the discussion beyond what happened in the panel and utilizes some of the questions that were posed, but never presented to the panelists due to lack of time. Contributing to the discussion are Ashish Darbari, CEO of Axiomise; Serge L... » read more

Trends In FPGA Verification Effort And Technology Adoption


The more we know about the bigger picture, context, historical and projected trends, or simply how other people do the same thing we do, the more efficiently and successfully we can do our specific jobs. This perspective also informs the EDA industry in how to best assist and sustain the needs of the FPGA and ASIC engineering communities. Providing this kind of information is the reason we c... » read more

Tapping Into Non-Volatile Logic


Research is underway to develop a new type of logic device, called non-volatile logic (NVL), based on ferroelectric FETs. FeFETs have been a topic of high interest at recent industry conferences, but the overwhelming focus has been using them in memory arrays. The memory bit cell, however, is simply a transistor that can store a state. That can be leveraged in other applications. “Non-v... » read more
