Why Silent Data Errors Are So Hard To Find


Cloud service providers have traced the source of silent data errors to defects in CPUs — as many as 1,000 parts per million — which produce faulty results only occasionally and under certain micro-architectural conditions. That makes them extremely hard to find. Silent data errors (SDEs) are random defects produced in manufacturing, not a design bug or software error. Those defects gene... » read more

Bump Co-Planarity And Inconsistencies Cause Yield, Reliability Issues


Bumps are a key component in many advanced packages, but at nanoscale levels making sure all those bumps have a consistent height is an increasing challenge. Without co-planarity, surfaces may not properly adhere. That can reduce yield if the problem is not identified in packaging, or it can cause reliability problems in the field. Identifying those issues requires a variety of process steps... » read more

Debug This! How To Simplify Coverage Analysis And Closure


For years the process of ASIC and FPGA design and verification debug consisted primarily of comprehending the structure and source code of the design with waveforms showing activity over time, based on testbench stimulus. Today, functional verification is exponentially complex with the emergence of new layers of design requirements (beyond basic functionality) that did not exist years ago — f... » read more

Week In Review: Semiconductor Manufacturing, Test


Micron selected Syracuse, New York as the site for its new megafab complex, which is expected to create 9,000 company jobs and 40,000 construction and supply chain jobs. President Biden called it “another win for America.” The chip manufacturing facility will be the nation’s largest, including a 7.2 million square foot complex and 2.4 million square foot of cleanroom. Site preparation wil... » read more

Week in Review: Design, Low Power


Could power beams be the key to smart city infrastructure and 5G/6G connectivity? A new report says both lasers and microwaves offer possible paths forward in this area, though both technologies come with benefits and drawbacks. Diminishing returns from process scaling, coupled with pervasive connectedness and an exponential increase in data, are driving broad changes in how chips are desi... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive, mobility Infineon opened a new factory in Cegléd, Hungary, for assembly and test of high-power semiconductor modules for EVs. “The new manufacturing capacities will help Infineon accommodate the growing demand for electromobility applications,” said Infineon’s COO Rutger Wijburg in a press release. Production ramp-up started in February 2022. Infineon also announced it will ... » read more

EVs Raise Energy, Power, And Thermal IC Design Challenges


The transition to electric vehicles is putting pressure on power grids to produce more energy and on vehicles to use that energy much more efficiently, creating a gargantuan set of challenges that will affect every segment of the automotive world, the infrastructure that supports it, and the chips that are required to make all of this work. From a semiconductor standpoint, improvements in th... » read more

Testing Chips For Security


Supply chains and manufacturing processes are becoming increasingly diverse, making it much harder to validate the security in complex chips. To make matters worse, it can be challenging to justify the time and expense to do so, and there’s little agreement on the ideal metrics and processes involved. Still, this is particularly important as chip architectures evolve from a single chip dev... » read more

Auto Safety Tech Adds New IC Design Challenges


The role of AI/ML in automobiles is widening as chipmakers incorporate more intelligence into chips used in vehicles, setting the stage for much safer vehicles, fewer accidents, but much more complex electronic systems. While full autonomy is still on the distant horizon, the short-term focus involves making sure drivers are aware of what's going on around them — pedestrians, objects, or o... » read more

Streamline DO-254 Compliance With Model-Based Design


By Eric Cigan, MathWorks, and Jacob Wiltgen, Siemens EDA The purpose of DO-254 (formally known as RTCA/ DO-254 or ED80) is to provide guidance for the development of airborne electronic hardware. The Federal Aviation Administration (FAA), European Aviation Safety Agency (EASA), and other worldwide aviation safety authorities require this standard to ensure that complex electronic hardware us... » read more
