Week In Review: Design, Low Power
By Jesse Allen - 27 Jul, 2018 - Comments: 0

Tools & IP Cadence uncorked the latest version of the Sigrity signal integrity analysis family of tools, adding a 3D design and 3D analysis environment integrated with Allegro PCB tools that allows users to import mechanical structures, such as cables and connectors, and merge them with the PCB for modeling and optimization as one structure. It also adds full Rigid-Flex PCB extraction from... » read more

How To Test Autonomous Vehicles
By Kevin Fogarty - 12 Jul, 2018 - Comments: 1

By Kevin Fogarty and Ed Sperling The race is on to develop ways of testing autonomous vehicles to prove they are safe under most road conditions, but this has turned out to be much more difficult than initially thought. The autonomous vehicle technology itself is still in various stages of development, with carmakers struggling to fine-tune AI algorithms that can guide robots on wheels th... » read more

Sensing without battery power Engineers at the National University of Singapore developed an IoT-focused sensor chip that can continue operating when its battery runs out of energy. The chip, BATLESS, uses a power management technique that allows it to self-start and continue to function under dim light without any battery assistance. The chip can operate in two different modes: minimum-ene... » read more

Design has consequences Carnegie Mellon University design students are exploring ways to enhance interactions with new technologies and the power of artificial intelligence. Assistant Professor Dan Lockton teaches the course, "Environments Studio IV: Designing Environments for Social Systems" in CMU's School of Design and leads the school's new Imaginaries Lab. “We want the designers of ... » read more

Ad hoc "cache hierarchies" Researchers at MIT and Carnegie Mellon University designed a system that reallocates cache access on the fly, to create new "cache hierarchies" tailored to the needs of particular programs. Dubbed Jenga, the system distinguishes between the physical locations of the separate memory banks that make up the shared cache. For each core, Jenga knows how long it would t... » read more

Synthetic Sensors: Towards General-Purpose Sensing (Carnegie Mellon Univ)
By Technical Paper Link - 16 May, 2017 - Comments: 0

Source: Carnegie Mellon University, Human-Computer Interaction Institute, Gierad Laput, Yang Zhang, Chris Harrison Although ubiquitous sensors seem almost synonymous with the IoT, some Carnegie Mellon University researchers say sensing with a single, general purpose sensor for each room may be better. The team has developed a plug-in sensor package that monitors multiple phenomena — sou... » read more

Refrigerator for quantum computers Quantum physicist Mikko Möttönen at Aalto University in Finland and his team have invented a quantum-circuit refrigerator, meant to reduce errors in quantum computing. The research results suggest how harmful errors in quantum computing can be removed — a new twist towards a functioning quantum computer. The team reminded that quantum computers use... » read more

Infrared links for data centers Researchers at Penn State, Stony Brook University and Carnegie Mellon University developed a free space optical link for communication in data centers using infrared lasers and receivers mounted on top of data center racks. According to Mohsen Kavehrad, professor of electrical engineering at Penn State, "It uses a very inexpensive lens, we get a very narrow... » read more

Legal Back in 2013, Synopsys filed suit against ATopTech for copyright infringement. The courts found in favor of Synopsys and ATopTech was damages were set at a little over $30M. With appeals unsuccessful, ATopTech announced that it has filed a voluntary petition under Chapter 11 of the Bankruptcy Code and has filed a motion to sell its businesses using a stalking horse bidder (an initial b... » read more

Getting to 1nm Researchers at the Lawrence Berkeley National Laboratory, UC Berkeley, University of Texas at Dallas, and Stanford University created a transistor with a working 1nm gate from carbon nanotubes and molybdenum disulfide (MoS2). "The semiconductor industry has long assumed that any gate below 5 nanometers wouldn't work, so anything below that was not even considered," said fir... » read more
