Minimizing Chip Aging Effects
By Brian Bailey - 13 Sep, 2018 - Comments: 2

Aging kills semiconductors, and it is a growing problem for an increasing number of semiconductor applications—especially as they migrate to more advanced nodes. Additional analysis and prevention methods are becoming necessary for safety critical applications. While some aspects of aging can be mitigated up front, others are tied to the operation of the device. What can an engineering tea... » read more

Variation In Low-Power FinFET Designs
By Ann Mutschler - 30 Aug, 2018 - Comments: 1

One of the biggest advantages of moving to the a leading edge process node is ultra-low voltage operation, where devices can achieve better performance using less power. But the latest generation process nodes also introduce a number of new challenges due to increased variation that can affect everything from signal integrity to manufacturing yield. While variation is generally well understo... » read more

AI Architectures Must Change
By Brian Bailey - 13 Aug, 2018 - Comments: 4

Using existing architectures for solving machine learning and artificial intelligence problems is becoming impractical. The total energy consumed by AI is rising significantly, and CPUs and GPUs increasingly are looking like the wrong tools for the job. Several roundtables have concluded the best opportunity for significant change happens when there is no legacy IP. Most designs have evolved... » read more

Chip Aging Becomes Design Problem
By Brian Bailey - 09 Aug, 2018 - Comments: 9

Chip aging is a growing problem at advanced nodes, but so far most design teams have not had to deal with it. That will change significantly as new reliability requirements roll out across markets such as automotive, which require a complete analysis of factors that affect aging. Understanding the underlying physics is critical, because it can lead to unexpected results and vulnerabilities. ... » read more

More Processing Everywhere
By Ed Sperling - 09 Aug, 2018 - Comments: 0

Simon Segars, CEO of Arm Holdings, sat down with Semiconductor Engineering to discuss security, power, the IoT, a big push at the edge, and the rise of 5G and China. What follows are excerpts of that conversation. SE: Are we making any progress in security? And even if Arm makes progress, does it matter, given there are so many things connected together? Segars: It feels like we’re maki... » read more

Process Variation Not A Solved Issue
By Ann Mutschler - 09 Aug, 2018 - Comments: 4

Semiconductor Engineering sat down to talk about process variation in advanced nodes, and how design teams are coping, with Christoph Sohrmann, a member of the Advanced Physical Verification group in Fraunhofer’s Division of Engineering of Adaptive Systems (EAS); Juan Rey, vice president of engineering at Mentor, A Siemens Business; and Stephen Crosher, CEO of Moortec Semiconductor. What foll... » read more

On-Chip Monitoring Of FinFETs
By Ed Sperling - 25 Jul, 2018 - Comments: 0

Stephen Crosher, CEO of Moortec, sat down with Semiconductor Engineering to discuss on-chip monitoring and its impact on power, security and reliability, including predictive maintenance. What follows are excerpts of that conversation. SE: What new problems are you seeing in design? Crosher: There are challenges emerging for companies working on advanced nodes, including scaling and trans... » read more

Safety, Security And PPA Tradeoffs
By Brian Bailey - 23 Jul, 2018 - Comments: 0

Safety and security are emerging as key design tradeoffs as chips are added into safety-critical markets, adding even more complexity into an already complicated optimization process. In the early days of semiconductor design, performance and area were traded off against each other. Then power became important, and the main tradeoffs became power, performance and area (PPA). But as chips inc... » read more

Data Center Power Poised To Rise
By Kevin Fogarty - 18 Jul, 2018 - Comments: 1

The big power-saving effort that kept U.S. data-center power consumption low for the past decade may not keep the lid on much longer. Faced with the possibility that data centers would consume a disastrously large percentage of the world's power supply, data center owners, and players in the computer, semiconductor, power and cooling industries ramped up effort to improve the efficiency of e... » read more

5nm Design Progress
By Ann Mutschler - 17 Jul, 2018 - Comments: 1

Activity surrounding the 5nm manufacturing process node is quickly ramping, creating a better picture of the myriad and increasingly complex design issues that must be overcome. Progress at each new node after 28nm has required an increasingly tight partnership between the foundries, which are developing new processes and rule decks, along with EDA and IP vendors, which are adding tools, met... » read more
