In-Vehicle Networks Are Safety, Security Dependent


It’s clear that managing, defining and prioritizing data traffic within vehicles is becoming an enormous challenge particularly with the growing number of networks , and underpining it all are safety and security concerns. Rob Knoth, product management director for the DSG group at Cadence observed, “The more you try to integrate traffic onto one bus, the more you are exposing systems th... » read more

Prioritizing Vehicle Data Traffic


It’s no surprise to hear that data complexity is on the rise inside vehicles today, but the scale just might cause you to gag on your coffee. It's expected that a fully connected car will upload as much as 30 gigabytes of data to the cloud every hour. Given the scale of data, it is imperative to make sure every bit of it is classified and tagged properly so that the subsystems, and inf... » read more

Clues to high-temp superconductivity Offering clues about the microscopic origins of high-temperature superconductivity, physicists at Rice University’s Center for Quantum Materials (RCQM) have created a new iron-based material. The material is a formulation of iron, sodium, copper and arsenic created by Rice graduate student Yu Song in the laboratory of physicist Pengcheng Dai. The recip... » read more

Architect Specs Harder To Follow


Interpreting and implementing architects' specifications is getting harder at each new process node, which is creating problems throughout the design flow, into manufacturing, and sometimes even post-production. Rising complexity and difficulties in scaling have pushed much more of the burden onto architects to deal with everything from complex power schemes, new packaging approaches, and to... » read more

Melting quantum crystal of electrons Confirming a fundamental phase transition in quantum mechanics that was theoretically proposed more than 80 years ago but not experimentally documented until now, MIT researchers reported that they’ve observed a highly ordered crystal of electrons in a semiconducting material and documented its melting, much like ice thawing into water. The team said i... » read more

What’s Missing In Advanced Packaging


Even though Moore's Law is running out of steam, there is still a need to increase functional density. Increasingly, this is being done with heterogeneous integration at the package or module level. This is proving harder than it looks. At this point there are no standardized methodologies, and tools often are retrofitted versions of existing tools that don't take into account the challenges... » read more

Removing quasiparticles from superconducting quantum circuits improves lifetime Given that an important prerequisite for the realization of high-performance quantum computers is that the stored data should remain intact for as long as possible, an international team of scientists at European interdisciplinary research institute Forschungszentrum Jülich has succeeded in making further improvem... » read more

Data, code sharing standards for computational studies While reporting new research results involves detailed descriptions of methods and materials used in an experiment, when a study uses computers to analyze data, create models or simulate things that can’t be tested in a lab, how can other researchers see what steps were taken or potentially reproduce results? To this end, a new report by... » read more

Embedded Software Verification Issues Grow


Embedded software is becoming more critical in managing the power and performance of complex designs, but so far there is no consensus about the best way to approach it—and that's creating problems. Even with safety-critical standards such as DO-178C for aerospace and [gettech id="31076" comment="ISO 26262"] for automotive, different groups of tool providers approach software from differen... » read more

Analog’s Rising Status


As more sensors and actuators are added into electronic devices, pressure is growing to more seamlessly move data seamlessly back and forth between analog and digital circuitry. [getkc id="37" kc_name="Analog"] and digital always have fit rather uncomfortably together, and that discomfort has grown as [getkc id="81" kc_name="SoCs"] are built using smaller feature sizes. While digital transis... » read more
