Airbus A320 Recall: Rethinking Fault Testing In Aerospace
By Marc Witteman - 08 Jan, 2026 - Comments: 0

Fault injection is usually discussed in the context of security, where adversaries deliberately induce faults to bypass protections or extract sensitive information. In safety engineering, by contrast, faults are often treated as rare, random events driven by natural or environmental factors. The recent Airbus A320 recall is a good example of how a primarily safety incident can still benefit fr... » read more

Streamlining DO-254 Compliance: The Power Of Automated Clock-Domain Crossing Verification
By Kurt Takara - 11 Dec, 2025 - Comments: 0

In the realm of safety-critical electronic hardware, particularly those governed by DO-254 compliance directives, ensuring design integrity is paramount. One of the most insidious challenges designers face is clock-domain crossing (CDC) violations. When data moves between asynchronous clock domains, it can lead to metastability issues, causing unpredictable behavior, data loss or corruption, an... » read more

LLMs Add Safety Risks To Physical AI
By Liz Allan - 06 Nov, 2025 - Comments: 0

Humanoid robots with artificial general intelligence are some years from entering our daily life, but application-specific robotics are already here. From Amazon’s fleet of fulfillment center robots to robotic surgical systems in operating rooms, search and rescue robo-dogs, autonomous drones, and last-mile delivery robots, all the way down to the humble Roomba vacuum cleaner, physical AI sys... » read more

ADAS/AD: Why An External Safety MCU Remains A Cornerstone For Safety Alongside SoC Safety Islands
By Joyce Chabert - 09 Oct, 2025 - Comments: 0

Advanced driver-assistance systems (ADAS) and autonomous driving (AD) technologies are revolutionizing mobility, making vehicles smarter, safer, and increasingly autonomous. At the heart of these advancements are sophisticated computing architectures built on system-on-chips (SoCs) that manage complex tasks like perception, decision-making, and control. Many SoCs integrate a "Safety Island"—a... » read more

Automotive OEMs Face Multiple Technology Adoption Challenges

Experts At The Table: The automotive ecosystem is in the midst of significant change. OEMs and tiered providers are grappling with how to deal with legacy technology while incorporating ever-increasing levels of autonomy, electrification, and software-defined vehicle concepts, just to name a few. Semiconductor Engineering sat down to discuss these and other related issues with Wayne Lyons, seni... » read more

Sensor Fusion Challenges In Automotive
By Ed Sperling - 02 May, 2024 - Comments: 0

The number of sensors in automobiles is growing rapidly alongside new safety features and increasing levels of autonomy. The challenge is integrating them in a way that makes sense, because these sensors are optimized for different types of data, sometimes with different resolution requirements even for the same type of data, and frequently with very different latency, power consumption, and re... » read more

Complex Safety Mechanisms Require Interoperability And Automation For Validation And Metric Closure
By Siemens EDA - 06 Mar, 2024 - Comments: 0

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
By Brian Bailey - 14 Aug, 2023 - Comments: 0

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
By Technical Paper Link - 15 Jul, 2023 - Comments: 0

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
By John Koon - 06 Jul, 2023 - Comments: 1

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
