Design For Reliability
By Brian Bailey - 15 Feb, 2021 - Comments: 1

Circuit aging is emerging as a mandatory design concern across a swath of end markets, particularly in markets where advanced-node chips are expected to last for more than a few years. Some chipmakers view this as a competitive opportunity, but others are unsure we fully understand how those devices will age. Aging is the latest in a long list of issues being pushed further left in the desig... » read more

Usage Models Driving Data Center Architecture Changes
By Ann Mutschler - 11 Feb, 2021 - Comments: 0

Data center architectures are undergoing a significant change, fueled by more data and much greater usage from remote locations. Part of this shift involves the need to move some processing closer to the various memory hierarchies, from SRAM to DRAM to storage. There is more data to process, and it takes less energy and time to process that data in place. But workloads also are being distrib... » read more

The Problem With Benchmarks
By Brian Bailey - 11 Feb, 2021 - Comments: 1

Benchmarks long have been used to compare products, but what makes a good benchmark and who should be trusted with their creation? The answer to those questions is more difficult than it may appear on the surface, and some benchmarks are being used in surprising ways. Everyone loves a simple, clear benchmark, but that is only possible when the selection criteria are equally simple. Unfortuna... » read more

Servers Are Becoming More Heterogeneous
By Andy Patrizio - 11 Feb, 2021 - Comments: 1

The number of CPUs in a server is growing, and so is the number of vendors that make those processors. CPU server build has been one, two, four, and occasionally more x86 processors, with IBM’s Power and Z series as the major exception. While x86 processors aren't necessarily being replaced, they are being complimented and augmented with new processor designs for a variety of more speciali... » read more

DRAM’s Persistent Threat To Chip Security
By Bryon Moyer - 10 Feb, 2021 - Comments: 0

A well-known DRAM vulnerability called "rowhammer," which allows an assailant to disrupt or take control of a system, continues to haunt the chip industry. Solutions have been tried, and new ones are being proposed, but the potential for a major attack persists. First discovered some five years ago, most of the efforts to eliminate the "rowhammer" threat have done little more than mitigate t... » read more

Automotive Test Moves In-System
By Bryon Moyer - 09 Feb, 2021 - Comments: 1

With the electrification of automobiles, it’s not enough to test the new electronics thoroughly at the end of the manufacturing process. Safety standards now require that tests be performed live, in the field, with contingency plans should a test fail. “We see clear demand from the automotive semiconductor supply chain for design functionality specifically aimed at in-system monitoring,�... » read more

Why Improving Auto Chip Reliability Is So Hard
By Susan Rambo - 09 Feb, 2021 - Comments: 1

Tools and ecosystems that focus on reliability and the long-term health of chips are starting to coalesce for the automotive electronics industry. Data gleaned from a chip’s lifecycle — design, verification, test, manufacturing, and in-field operation — will become key to achieving the longevity, reliability, functional safety, and security of newer generations of automobiles. Having s... » read more

Data Issues Mount In Chip Manufacturing
By Anne Meixner - 09 Feb, 2021 - Comments: 2

For yield management systems the old calculation adage, "garbage in/garbage out" still rings true. Aligning and cleaning data remains a dirty business. With the increased value in data in the semiconductor supply chain, there now are essentially two supply chains running in parallel. One involves the physical product being created, while the other includes the data associated with each proce... » read more

Longer Chip Lifecycles Increase Security Threat
By Ed Sperling - 04 Feb, 2021 - Comments: 0

The longer chips and electronic systems remain in use, the more they will need to be refreshed with software and firmware updates. That creates a whole new level of security risks, ranging from over-the-air intercepts to compromised supply chains. These problems have been escalating as more devices are connected to the Internet and to each other, but it's particularly worrisome when it invol... » read more

Bridging The Gap Between Smart Cities And Autonomous Vehicles
By Ann Mutschler - 04 Feb, 2021 - Comments: 0

Smart city planners and carmakers are wrestling with similar problems and goals, but they are working at very different paces and often with different technologies — despite the fact that these two worlds will need to be bridged in order to be useful. Moving traffic optimally in urban areas is critical for reducing energy consumption and accidents, and for moving emergency vehicles through... » read more
