End-To-End Traceability


Despite standards such as ISO 26262 and IEC 61508, there are still disconnects and gaps in the supply chain and design-through-manufacturing flows. Kurt Shuler, vice president of marketing at Arteris IP, digs into what's missing, why changes made in one area are not reflected in other areas and throughout the product lifecycle, and why various different phases of the flow don't always match up ... » read more

Uncovering In-DRAM RowHammer Protection Mechanisms: A New Methodology, Custom RowHammer Patterns, and Implications


Abstract: "The RowHammer vulnerability in DRAM is a critical threat to system security. To protect against RowHammer, vendors commit to security-through-obscurity: modern DRAM chips rely on undocumented, proprietary, on-die mitigations, commonly known as Target Row Refresh (TRR). At a high level, TRR detects and refreshes potential RowHammer-victim rows, but its exact are not openly disclose... » read more

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

Enablers And Barriers For Connecting Diverse Data


More data is being collected at every step of the manufacturing process, raising the possibility of combining data in new ways to solve engineering problems. But this is far from simple, and combining results is not always possible. The semiconductor industry’s thirst for data has created oceans of it from the manufacturing process. In addition, semiconductor designs large and small now ha... » read more

Reversible Chain Diagnosis


For advanced technologies, the industry is seeing very complicated silicon defect types and defect distribution. One consequence is that scan chain diagnosis becomes more difficult. To improve the resolution of scan chain diagnosis, Tessent Diagnosis can use new scan chain test patterns to leverage a reversible scan chain architecture. This paper describes the novel scan chain architecture t... » read more

Strategies For Meeting Stringent Standards For Automotive ICs


It may surprise you, but when it comes to chips in electronic braking systems, airbag control units, and more, automotive manufacturers are still using 10-year-old technology — and with good reason. For the automotive industry, the reliability, stability, and robustness of electronic components are critical, especially when it comes to meeting the stringent Automotive Electronics Council (... » read more

Improving Accuracy In Satellite Navigation Systems


Increasing dependency on the global navigation satellite system (GNSS) constellations is raising concerns about what happens when signals are unavailable, even for short periods of time. GNSS systems affect our daily lives in ways we often don’t see, from location services to cell phone timing. In fact, these satellites have become a necessary part of critical infrastructure, and higher ac... » read more

Challenges In RF Design


Designing highly integrated components for radio frequency applications poses special challenges for system engineers, designers and the commissioning engineers. The boundary between chip, package and board is increasingly vanishing on modern components. It is growing more common for parts of the functionality to be moved to the package or even the board. In some cases, the requirements have be... » read more

Introducing mPower


Power integrity analysis evaluates circuits to determine if they will provide their designed/intended performance and reliability as implemented. Designers must be able to verify analog and digital power integrity from the RTL/gate-level through die-level integrations up to the package and board system-level. The mPower toolset is an innovative power integrity verification solution that brings ... » read more

The Everything New Syndrome


Technology is all about the latest features, the fastest processing, with the lowest power. While that sounds great in marketing pitch, any or all of those factors don't necessarily equate to a better product or long-term user satisfaction. There's a reason semiconductor companies are conservative by nature. They want to know that when they spend tens or hundreds of millions of dollars on a ... » read more
