Complex Safety Mechanisms Require Interoperability And Automation For Validation And Metric Closure


The race to autonomous mobility among the automobile manufacturers is driving the evolution of the underlying semiconductors. As a result, semiconductor technologies are moving towards higher densities and lower operating voltages, and this migration is introducing increasing sensitivity to random hardware failures – the failures which occur unpredictably over a semiconductor’s lifetime. Mo... » read more

Why It’s So Difficult To Ensure System Safety Over Time


Safety is emerging as a concern across an increasing number of industries, but standards and methodologies are not in place to ensure electronic systems attain a defined level of safety over time. Much of this falls on the shoulders of the chip industry, which provides the underlying technology, and it raises questions about what more can be done to improve safety. A crude taxonomy recently ... » read more

RowPress: Read-Disturb Phenomenon In DDR4 DRAM Chips


A technical paper titled "RowPress: Amplifying Read Disturbance in Modern DRAM Chips" was published by researchers at ETH Zürich. Abstract: "Memory isolation is critical for system reliability, security, and safety. Unfortunately, read disturbance can break memory isolation in modern DRAM chips. For example, RowHammer is a well-studied read-disturb phenomenon where repeatedly opening and clo... » read more

Curbing Automotive Cybersecurity Attacks


The relentless cyberattacks on the automotive sector are not limited to vehicles and have an impact on the entire automotive supply chain, so the pressure is on the automotive ecosystem to understand the necessary standards and regulations for vehicles and components. While the process of attaining compliance adds additional effort, in the long run, the increase in cybersecurity will save the a... » read more

Verification And Test Of Safety And Security


Functional verification can cost as much as design, but new capabilities are piling onto an already stressed verification methodology, leaving solutions fragmented and incomplete. In a perfect world, a semiconductor device would be verified to operate according to its complete specification, and continue to operate correctly over the course of its useful life. The reality, however, is this i... » read more

The True Cost Of Software Changes


Safety and security are considered to be important in a growing number of markets and applications. Guidelines are put in place for the processes used to develop either the hardware or the software, but what they seem to ignore is that neither exists in a vacuum. They form a system when put together. Back when I was developing tools for hardware-software co-verification, there were fairly co... » read more

ML Automotive Chip Design Takes Off


Machine learning is increasingly being deployed across a wide swath of chips and electronics in automobiles, both for improving reliability of standard parts and for the creation of extremely complex AI chips used in increasingly autonomous applications. On the design side, the majority of EDA tools today rely on reinforcement learning, a machine learning subset of AI that teaches a machine ... » read more

State of the Art And Future Directions of Rowhammer (ETH Zurich)


A new technical paper titled "Fundamentally Understanding and Solving RowHammer" was published by researchers at ETH Zurich. Abstract "We provide an overview of recent developments and future directions in the RowHammer vulnerability that plagues modern DRAM (Dynamic Random Memory Access) chips, which are used in almost all computing systems as main memory. RowHammer is the phenomenon in... » read more

Growing Challenges For Increasingly Connected Vehicles


Automobiles will become increasingly connected over the next decade, but that connectivity will come at a price in terms of dollars, security, and constantly changing technology. Connectivity involves all parts of a vehicle. It includes everything from autonomous driving to in-cabin monitoring and connected infotainment. And it encompasses external sensors, IoT, V2X, over-the-air communicati... » read more

Safety, Security, And Reliability Of AI In Autos


Experts at the Table: Semiconductor Engineering sat down to talk about security, aging, and safety in automotive AI systems, with Geoff Tate, CEO of Flex Logix; Veerbhan Kheterpal, CEO of Quadric; Steve Teig, CEO of Perceive; and Kurt Busch, CEO of Syntiant. What follows are excerpts of that conversation, which was held in front of a live audience at DesignCon. Part one of this discussion is he... » read more
