Designing For In-Circuit Monitors


In every application space the semiconductor ecosystem touches, in-circuit monitors and sensors are playing an increasing role in silicon lifecycle management and concepts around reliability and resiliency — both during design as well as in the field. The combination of true system-level design, in/on-chip monitors, and improved data analysis are expected to drastically improve reliability... » read more

Silicon Lifecycle Management Advances With Unified Analytics


In a typical day in the life of a product engineer, they have gone through the requisite wafer sort testing in manufacturing with the next step to assemble the resultant good die into their respective packages. While performing a series of parametric tests during final test, yield issues are encountered and the process of finding the source of the issues begins. Luckily, with access to a good d... » read more

Chip Monitoring For Max Performance And Security


In a semiconductor market dominated by SoCs for high-performance computing, AI, automotive and 5G, semiconductor companies face myriad challenges and device requirements. The specific challenges for any given SoC vary but can include issues around performance debug and security against hacking. Top of the list includes the need to ensure quality, enhance safety, optimize performance, and increa... » read more

Auto Cyberattacks Becoming More Widespread


As vehicles become smarter, more complex, and increasingly connected, they also become more prone to cyberattacks. The challenge now is to keep pace with hackers, who are continually devising new and innovative ways to attack both software and hardware in vehicles. Recent statistics bear this out. In 2022, there was a big spike in deep/dark web activity and incidents related to application p... » read more

How To Raise Reliability, Availability, And Serviceability Levels For HPC SoCs


By Charlie Matar, Rita Horner, and Pawini Mahajan While once the domain of large data centers and supercomputers, high-performance computing (HPC) has become rather ubiquitous and, in some cases, essential in our everyday lives. Because of this, reliability, availability, and serviceability, or RAS, is a concept that more HPC SoC designers should familiarize themselves with. RAS may sound... » read more

Hunting For Hardware-Related Errors In Data Centers


The semiconductor industry is urgently pursuing design, monitoring, and testing strategies to help identify and eliminate hardware defects that can cause catastrophic errors. Corrupt execution errors, also known as silent data errors, cannot be fully isolated at test — even with system-level testing — because they occur only under specific conditions. To sort out the environmental condit... » read more

Ramping Up IC Predictive Maintenance


The chip industry is starting to add technology that can predict impending failures early enough to stave off serious problems, both in manufacturing and in the field. Engineers increasingly are employing in-circuit monitors embedded in SoC designs to catch device failures earlier in the production flow. But for ICs in the field, data tracing from design to application use only recently has ... » read more

Ensuring Memory Reliability Throughout the Silicon Lifecycle


By Anand Thiruvengadam and Guy Cortez Memories are everywhere in modern electronics. Discrete memory chips account for much of the space on printed circuit boards (PCBs). Embedded memories consume much of the floorplan in system-on-chip (SoC) devices. Many multi-die chip configurations, including 2.5D/3DIC devices, are driven by the need for faster memory access. Designing and verifying memo... » read more

Automotive Applications Demand Silicon Lifecycle Management


Every electrical engineer learns early in university studies that automobiles are a highly demanding environment for electronics. Temperature and humidity extremes, noise and vibration, electrical interference, exposure to alpha particles, and other factors all make it hard to design and manufacture chips that will operate properly under all conditions. These challenges are exacerbated as chips... » read more

Optimizing Vmin With Path Margin Monitors


By Firooz Massoudi and Ash Patel Choosing the right operating voltage for various digital blocks within a semiconductor device is one of the most important tasks faced by chip designers. Operating voltage has major effects on performance, power consumption, and reliability. Increasing the voltage generally increases performance, but at the cost of more power and higher lifetime operating cos... » read more
