Bandwidth Utilization Side-Channel On ML Inference Accelerators


Abstract—Accelerators used for machine learning (ML) inference provide great performance benefits over CPUs. Securing confidential model in inference against off-chip side-channel attacks is critical in harnessing the performance advantage in practice. Data and memory address encryption has been recently proposed to defend against off-chip attacks. In this paper, we demonstrate that bandwidth... » read more

Failure Modes Of Wearable Electronics


Society has been enamored with wearable electronics for many years. From FitBit to Google Glass to Apple Watch, taking electronic technology to the next level has fascinated us. Wiki defines wearable computers (also known as body-borne computers or wearables) as miniature electronic devices that are worn by the bearer under, with or on top of clothing. This class of wearable technology has been... » read more

Reversible Chain Diagnosis


For advanced technologies, the industry is seeing very complicated silicon defect types and defect distribution. One consequence is that scan chain diagnosis becomes more difficult. To improve the resolution of scan chain diagnosis, Tessent Diagnosis can use new scan chain test patterns to leverage a reversible scan chain architecture. This paper describes the novel scan chain architecture t... » read more

Industrial Radiography — CT Scanning for Metrology Applications


Xray technology, more specifically computed tomography (CT), has been adapted for use as an instrument of industrial metrology. Early adopters have quickly recognized the benefits of internal and external nondestructive testing for 3D defect detection and geometric analysis, while those considering adoption may be uncertain how to implement the technology effectively. This study was conducted t... » read more

Imaging Of Overlay And Alignment Markers Under Opaque Layers Using Picosecond Laser Acoustic Measurements


Optically opaque materials present a series of challenges for alignment and overlay in the semi-damascene process flow or after the processing of the magnetic tunnel junction (MTJ) of a Magnetic Random-Access Memory (MRAM). The overlay and alignment of a lithographically defined pattern on top of the pattern and the underlying layer is fundamental to device operation in all multi-layer patterne... » read more

How To Reduce The Impact Of The Global Microcontroller Shortage On ECU Software Development


The COVID-19 pandemic had a massive impact on all facets of business and commerce, as widespread supply chain disruptions rippled through every industry. Multiple factors collided to create a global microcontroller shortage that is now impacting the automotive industry, and is forcing developers to redesign Electronic Control Units (ECUs) using alternative Microcontrollers (MCUs) and to otherwi... » read more

RF/Microwave Technology Driving The Connected Car


In-car networks and advanced driver-assistance systems (ADAS), made possible through wireless sensors, driver-assist radar, vehicle communications, and related electronics, present many design challenges to engineers. Simulation software enables design teams to effectively manage the complex design and integration challenges associated with developing these high-speed and RF-enabled networks. T... » read more

ML-based Routing Congestion And Delay Estimation In Vivado ML Edition


The FPGA physical design flow offers a compelling opportunity for Machine Learning for CAD (MLCAD) for the following reasons: • An ML solution can be applied wholesale to a device family. • There is a vast data farm that can be harvested from device models and design data from broad applications. • There is a single streamlined design flow that an be instrumented, annotated, and quer... » read more

How Semiconductor Solutions Address Safety Requirements Of Future Power Distribution Networks In Autonomous Vehicles


Open up the bonnet of any modern automobile and many of us would be hard-pressed to find anything that we could fix ourselves. With pipes and cables almost artistically integrated into the engine bay, and sleek plastic covers fitted everywhere, there is very little that can still be recognized, yet alone repaired. Perhaps the only location where we feel comfortable is the “fuse box”, or pow... » read more
