Impact Of GAA Transistors At 3/2nm
By Brian Bailey - 16 Aug, 2021 - Comments: 2

The chip industry is poised for another change in transistor structure as gate-all-around (GAA) FETs replace finFETs at 3nm and below, creating a new set of challenges for design teams that will need to be fully understood and addressed. GAA FETs are considered an evolutionary step from finFETs, but the impact on design flows and tools is still expected to be significant. GAA FETs will offer... » read more

Condition Monitoring Of Drive Trains By Data Fusion Of Acoustic Emission And Vibration Sensors
By Fraunhofer IIS/EAS - 13 Aug, 2021 - Comments: 0

Early damage detection and classification by condition monitoring systems is crucial to enable predictive maintenance of manufacturing systems and industrial facilities. The data analysis can be improved by applying machine learning algorithms and fusion of data from heterogenous sensors. This paper presents an approach for a step-wise integration of classifications gained from vibration and ac... » read more

Adding Circuit Aging To Variability
By Brian Bailey - 12 Aug, 2021 - Comments: 0

Moving to a smaller node usually means another factor becomes important. The industry has become accustomed to doing process, temperature, voltage (PVT) corner analysis, but now it has to add aging into that mix. The problem is that planning for circuit aging is no longer a purely statistical process. Aging is dependent on activity over the lifetime of the device. Tools need to be modified a... » read more

Functional Safety: Current Status And Perspectives With A View Toward Standardization Bodies
By Jens Michael Warmuth - 12 Aug, 2021 - Comments: 0

Functional safety is a topic highly driven by standards. This is due in part to legislation and regulation, but it also arises from the fact that functional safety spans a wide range of fields. Even before specific standards were introduced, there were products that met the social consensus on safety. For example, carmakers were making cars that were safe and incorporated electrical and elec... » read more

Designing Chips In A ‘Lawless’ Industry
By Ed Sperling - 02 Aug, 2021 - Comments: 2

The guideposts for designing chips are disappearing or becoming less relevant. While engineers today have many more options for customizing a design, they have little direction about what works best for specific applications or what the return on investment will be for those efforts. For chip architects, this is proving to be an embarrassment of riches. However, that design freedom comes wit... » read more

Chipmakers Getting Serious About Integrated Photonics
By Brian Bailey - 12 Jul, 2021 - Comments: 3

Integrating photonics into semiconductors is gaining traction, particularly in heterogeneous multi-die packages, as chipmakers search for new ways to overcome power limitations and deal with increasing volumes of data. Power has been a growing concern since the end of Dennard scaling, which happened somewhere around the 90nm node. There are more transistors per mm², and the wires are thinne... » read more

Getting Realistic About AI
By Olaf Enge-Rosenblatt - 12 Jul, 2021 - Comments: 0

By Olaf Enge-Rosenblatt and Andy Heinig The topic of artificial intelligence (AI) is omnipresent today, both in the news and on popular science shows. The number of possibilities for AI methods to assist people in making decisions are expanding rapidly. There are three main reasons for this: The development of new AI methods (deep learning, reinforcement learning); The continuous ... » read more

Dynamic Fault Injection Into Digital Twins Of Safety-Critical Systems
By Fraunhofer IIS/EAS - 07 Jul, 2021 - Comments: 0

In this work we present a technology for dynamically introducing fault structures into digital twins without the need to change the virtual prototype model. The injection is done at the beginning of a simulation by dynamically rewiring the involved netlists. During the simulation on a real-time platform, faults can be activated or deactivated triggered by sequences, statistical effects or by ev... » read more

Virtual Prototyping In SoC Development
By Christoph Sohrmann - 21 Jun, 2021 - Comments: 0

Modern semiconductor technologies enable manufacturers to pack more and more functions and memory into a single silicon die. While steadily advancing microintegration based on Moore’s Law just a few years ago mainly focused on increasing the clock frequency of integrated circuits (IC), today, it’s the design complexity and number of blocks that enable new IC functions. More and more logic b... » read more

Shifting Toward Data-Driven Chip Architectures
By Ed Sperling and Ann Mutschler - 16 Jun, 2021 - Comments: 0

An explosion in data is forcing chipmakers to rethink where to process data, which are the best types of processors and memories for different types of data, and how to structure, partition and prioritize the movement of raw and processed data. New chips from systems companies such as Google, Facebook, Alibaba, and IBM all incorporate this approach. So do those developed by vendors like Appl... » read more
