Dealing With Sub-Threshold Variation


Chipmakers are pushing into sub-threshold operation in an effort to prolong battery life and reduce energy costs, adding a whole new set of challenges for design teams. While process and environmental variation long have been concerns for advanced silicon process nodes, most designs operate in the standard “super-threshold” regime. Sub-threshold designs, in contrast, have unique variatio... » read more

Difficult Memory Choices In AI Systems


The number of memory choices and architectures is exploding, driven by the rapid evolution in AI and machine learning chips being designed for a wide range of very different end markets and systems. Models for some of these systems can range in size from 10 billion to 100 billion parameters, and they can vary greatly from one chip or application to the next. Neural network training and infer... » read more

Arm Goes For Performance


At the recent Linley Processor Conference, Arm presented two processors. This was regarded as so confidential that the original pre-conference version of the presentations didn't contain the Arm one, even though that pdf was only put online about an hour before. But most of the outline of what they presented they already talked about in May, a few months ago. I said recently that this seem... » read more

Blog Review: Nov. 11


Mentor's Chris Spear proposes mixing together the compactness of the field macro style with the preciseness of the do methods when writing a UVM transaction class. Cadence's Paul McLellan looks back at the history of EPROM, some of the difficulty with actually erasing it, and the subsequent development of EEPROM. Synopsys' Tuomo Untinen explains three WPA2 authentication vulnerabilities r... » read more

Modified X-Band Push-Push Oscillator Simulation And Measurement


This eBook that explores the push-push oscillator configuration via harmonic balance (HB) computer simulation and test measurement. The unique operation of the push-push oscillator configuration is explored using HB simulation of spectral content and time-domain voltage waveforms. Dynamic load lines are investigated and utilized to explore peak signal excursion and degree of nonlinearity. Predi... » read more

Growing Complexity Adds To Auto IC Safety Challenges


The automotive industry is working to streamline, automate and tame verification of automotive electronic control units, SoCs and other chips used in vehicles, many of which are becoming so complex and intertwined that progress is getting bogged down. Modern cars may have up to 100 ECUs, which control such vehicle functions as engine, powertrain, transmission, brakes, suspension, entertainme... » read more

New And Innovative Supply Chain Threats Emerging


The electronics supply chain is seeing evidence of increased sophistication in the counterfeiting of complex ICs and simple passives, both of which can impact the functioning and safety of the systems that use them. New technologies are being developed to build trust by helping to identify counterfeit devices before assembly and during failure analysis. It's too early to tell how effective t... » read more

Dealing With Security Holes In Chips


Semiconductor Engineering sat down to discuss security risks across multiple market segments with Helena Handschuh, security technologies fellow at Rambus; Mike Borza, principal security technologist for the Solutions Group at Synopsys; Steve Carlson, director of aerospace and defense solutions at Cadence; Alric Althoff, senior hardware security engineer at Tortuga Logic; and Joe Kiniry, princi... » read more

Electronics In Agriculture


In my post Jobs: Farmer I wrote about my experience as a teenager working on the farm owned (actually rented from the Duke of Badminton) by the father of one of my school friends. Electronics were nowhere to be found in those days. I recently watched some YouTube videos that show just how hi-tech farming has become now that Moore's Law has made accessible electronics that would have seemed ma... » read more

Blog Review: Nov. 4


Arm's Joshua Sowerby points to how to improve machine learning performance on mobile devices by using smart pruning to remove convolution filters from a network, reducing its size, complexity, and memory footprint. Mentor's Neil Johnson checks out how designers can write and verify RTL real-time using formal property checking in the style of test-driven development and why to give it a try. ... » read more
