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

The Search For 5G mmWave Filters
By Bryon Moyer - 12 Aug, 2021 - Comments: 0

Cellular telephone technology takes advantage of a large number of frequency bands to provide ever-increasing bandwidth for mobile use. Each of those bands needs a filter to keep its signals separate from other bands, but the filter technologies in current use for cellphones may not scale up to the full millimeter-wave (mmWave) range planned for 5G. “MmWave will happen,” said Mike Eddy, ... » read more

Has Computational Storage Finally Arrived?
By Andy Patrizio - 11 Aug, 2021 - Comments: 2

The idea behind computational storage is not new. It’s just that like so many concepts, the idea has been well ahead of the technology. In a nutshell, computational storage brings processing power to the storage level. It eliminates the need to load data from the storage system into memory for processing. Moving data between storage and compute resources is inefficient and computational sy... » read more

Designing Chips For Test Data
By Ed Sperling - 10 Aug, 2021 - Comments: 0

Collecting data to determine the health of a chip throughout its lifecycle is becoming necessary as chips are used in more critical applications, but being able to access that data isn't always so simple. It requires moving signals through a complex, sometimes unpredictable, and often hostile environment, which is a daunting challenge under the best of conditions. There is a growing sense of... » read more

Why Wafer Bumps Are Suddenly So Important
By Anne Meixner - 10 Aug, 2021 - Comments: 2

Wafer bumps need to be uniform in height to facilitate subsequent manufacturing steps, but a push for 100% inspection in packaging in mission-critical markets is putting a strain on existing measurement technologies. Bump co-planarity is essentially a measure of flatness. Specifically, it measures the variation in bump height, which may have a target, for example, of about 100 microns. As a ... » read more

Who Owns In-Chip Monitoring Data?
By Bryon Moyer - 10 Aug, 2021 - Comments: 1

In-chip monitors provide unprecedented visibility into the inner workings of complex integrated circuits for everything from process control to fine binning, preventive system maintenance, and failure analysis. But there may be many consumers of different slices of the data at very different phases of the chip lifecycle, raising questions about who controls and owns all of that data. The ans... » read more

Automotive Lidar Technologies Battle It Out
By Bryon Moyer - 05 Aug, 2021 - Comments: 1

Lidar is likely to be added to the list of sensors that future cars will use to help with navigation and safety, but most likely it won't be the large rotating mirror assembly on the top of vehicles. Newer solid-state radar technologies are being researched and developed, although it’s not yet clear which of these will win. “The benefits of lidar technology are well known dating back to ... » read more

Auto Displays: Bigger, Brighter, More Numerous
By Ann Mutschler - 05 Aug, 2021 - Comments: 0

Displays are rapidly becoming more critical to the central brains in automobiles, accelerating the adoption and evolution of this technology to handle multiple types of audio, visual, and other data traffic coming into and flowing throughout the vehicle. These changes are having a broad impact on the entire design-through-manufacturing flow for display chip architectures. In the past, these ... » read more

Will PAYGO Shake Up How We Pay for Chips?
By Bryon Moyer - 05 Aug, 2021 - Comments: 0

System builders are used to buying integrated circuits on a simple transactional basis — the chip has a price, and that’s what you pay. But some application spaces may have a wide variety of capabilities that need hardware support, and each feature may not be used for every instance. Traditionally, one would design different chips for different feature mixes and price points. But a new p... » read more

Startup Funding: July 2021
By Jesse Allen - 04 Aug, 2021 - Comments: 0

The trend of big funding for Chinese autonomous driving companies continued in July, with three startups each drawing $100M or more for efforts in ADAS and computer vision for automotive. The month also saw one electric vehicle manufacturer get a massive boost as it begins production on its first models, while significant funding also went to a company that wants to recycle used up EV batteries... » read more
