A Deeper Look into RowHammer’s Sensitivities: Experimental Analysis of Real DRAM Chips and Implications on Future Attacks and Defenses


Abstract "RowHammer is a circuit-level DRAM vulnerability where repeatedly accessing (i.e., hammering) a DRAM row can cause bit flips in physically nearby rows. The RowHammer vulnerability worsens as DRAM cell size and cell-to-cell spacing shrink. Recent studies demonstrate that modern DRAM chips, including chips previously marketed as RowHammer-safe, are even more vulnerable to RowHammer than... » read more

Auto Displays: Bigger, Brighter, More Numerous


Displays are rapidly becoming more critical to the central brains in automobiles, accelerating the adoption and evolution of this technology to handle multiple types of audio, visual, and other data traffic coming into and flowing throughout the vehicle. These changes are having a broad impact on the entire design-through-manufacturing flow for display chip architectures. In the past, these ... » read more

Beyond Bug Hunting: Verification Coverage From Safety To Certification


Understanding verification coverage is critical for meeting IC integrity standards and goes well beyond detecting bugs in the design. Without proper verification coverage metrics, meeting strict safety standards and certification may not be achievable. Precise metrics indicate where there are gaps in verification and provide a clear view of the progress being made in the verification effort. Co... » read more

Automotive Safety Island


The promise of autonomous vehicles is driving profound changes in the design and testing of automotive semiconductor parts. Automotive ICs, once deployed for simple functions like controlling windows, are now performing complex functions related to advanced driver-assist systems (ADAS) and autonomous driving applications. The processing power required results in very large and complex ICs that ... » read more

Selective Redundancy In Cars


The automotive industry has been fish-tailing its way through design strategies and electronics architectures, but it finally appears to be honing in on a strategy that actually might work. This doesn't mean fully autonomous vehicles will take over the road anytime soon, but at least it points carmakers in the right direction. The auto industry has been in panic mode ever since Tesla, Waymo,... » read more

Growing Complexity Adds To Auto IC Safety Challenges


The automotive industry is working to streamline, automate and tame verification of automotive electronic control units, SoCs and other chips used in vehicles, many of which are becoming so complex and intertwined that progress is getting bogged down. Modern cars may have up to 100 ECUs, which control such vehicle functions as engine, powertrain, transmission, brakes, suspension, entertainme... » read more

Secure Silicon Lifecycle Management Architecture For Functional Safety


The rapid growth of electronics for automotive applications fueled by advanced ADAS systems pose new challenges for complex SoC design and Silicon Lifecycle Management (SLM) in the supply chain as well as in-field monitoring and management of the population of chips. In these modern complex devices, ensuring the correct and safe operation requires not only functional safety to check for reli... » read more

Week In Review: Design, Low Power


Arteris IP will acquire the assets of Magillem Design Services, combining Arteris' NoC interconnect IP with Magillem's chip design and assembly environment. Magillem’s software products will continue to be offered separately from the Arteris interconnect IP offerings and the joined company will continue to execute on Magillem’s existing product and technology roadmaps. Substantially all Mag... » read more

Virtualization In The Car


As the automotive industry grapples with complexity due to electrification and increasing autonomy of vehicles, consolidation of ECUs within vehicles, more stringent safety and security requirements, automotive ecosystem players are looking to virtualization concepts in a number of ways to realize the vehicles of tomorrow. One way is with hardware virtualization; the ability of a device such... » read more
