Building Security Into RISC-V Systems


Semiconductor Engineering sat down with Helena Handschuh, a Rambus fellow; Richard Newell, senior principal product architect at Microsemi, a Microchip Company; and Joseph Kiniry, principal scientist at Galois. Part one is here. (This is the second of two parts.) L-R: Joseph Kiniry, Helena Handschuh, Richard Newell. SE: Some of the new applications for hardware designs are tied to AI, d... » read more

Week In Review: Manufacturing, Test


OEMs and chipmakers Apple has reduced its revenue outlook to $84 billion for the quarter, down from $89 billion to $93 billion in its original forecast. The consensus on Wall Street was $91 billion. “The guide down was mostly attributed to weaker-than-expected iPhone demand in emerging markets, predominantly China,” said John Vinh, an analyst with KeyBanc Capital Markets, in a research not... » read more

Open-Source RISC-V Hardware And Security


Semiconductor Engineering sat down with Helena Handschuh, a Rambus fellow; Richard Newell, senior principal product architect at Microsemi, a Microchip Company; and Joseph Kiniry, principal scientist at Galois. What follows are excerpts of that conversation. (L-R) Joseph Kiniry, Helena Handschuh and Richard Newell. SE: Is open-source hardware more secure, or does it just open up vulnera... » read more

Virtual Design Chains At The EDA Forum


The German edacentrum’s EDA Forum was held in Berlin, Germany, in early November. It was very interesting to see the design chain effects in the automotive domain, very visible in a panel yours truly was part of, together with Audi, Bosch, Infineon, MicroChip, Synopsys, Mentor, and the BMBF. Driven from the top of the design chain, the direction is clearly to go more virtual to optimize the c... » read more

Looking Beyond The CPU


CPUs no longer deliver the same kind of of performance improvements as in the past, raising questions across the industry about what comes next. The growth in processing power delivered by a single CPU core began stalling out at the beginning of the decade, when power-related issues such as heat and noise forced processor companies to add more cores rather than pushing up the clock frequency... » read more

Foundries Prepare For Battle At 22nm


After introducing new 22nm processes over the last year or two, foundries are gearing up the technology for production—and preparing for a showdown. GlobalFoundries, Intel, TSMC and UMC are developing and/or expanding their efforts at 22nm amid signs this node could generate substantial business for applications like automotive, IoT and wireless. But foundry customers face some tough choic... » read more

Why Chips Die


Semiconductor devices contain hundreds of millions of transistors operating at extreme temperatures and in hostile environments, so it should come as no surprise that many of these devices fail to operate as expected or have a finite lifetime. Some devices never make it out of the lab and many others die in the fab. It is hoped that most devices released into products will survive until they be... » read more

FAA Traffic Management Anticipates Flying Cars


It may be a year or more before the U.S. Federal Aviation Administration (FAA) changes its rules enough for Amazon or other hopefuls to deliver products by drones. But the five-year FAA Reauthorization Act of 2018, signed into law Oct. 5, confirmed controversial rules the FAA considers critical to its ability to regulate drone traffic and confirmed funding and plans for drone-specific additi... » read more

Power Delivery Affecting Performance At 7nm


Complex interactions and dependencies at 7nm and beyond can create unexpected performance drops in chips that cannot always be caught by signoff tools. This isn't for lack of effort. The amount of time spent trying to determine if an advanced-node chip will work after it is fabricated has been rising steadily for several process nodes. Additional design rules handle everything from variation... » read more

Embedded Flash Scaling Limits


Embedded nonvolatile flash memory has played a key role in chips for years, but the technology is beginning to face some scaling and cost roadblocks and it’s not clear what comes next. Embedded flash is used in several markets, such as automotive, consumer and industrial. But the automotive sector appears to be the most concerned about the future of the technology. Typically, a car incorpo... » read more
