Impacts Of Reliability On Power And Performance


Making sure a complex system performs as planned, and providing proper access to memories, requires a series of delicate tradeoffs that often were ignored in the past. But with performance improvements increasingly tied to architectures and microarchitectures, rather than just scaling to the next node, approaches such as determinism and different kinds of caching increasingly are becoming criti... » read more

Autonomous Vehicle Design Begins To Change Direction


Tools that are commonly used in semiconductor design are starting to be applied at the system level for assisted and autonomous vehicles, setting the stage for more complex simulated scenarios and electronic system design. Simulation is well understood for designing automotive ICs, but now it also is being used to design vehicle architectures and sensors, as well as for sensor miniaturizatio... » read more

Mitigating Risk Through Verification


Verification is all about mitigating risk, and one of the growing issues alongside of increasing complexity and new architectures is coverage. The whole notion of coverage is making sure a chip will work as designed. That requires determining the effectiveness of the simulation tests that stimulate it, and its effectiveness in terms of activating structures of functional behavior and design.... » read more

High precision system for self-driving car navigation Based on technology developed by ETH Zurich researchers, Fixposition is a spin-off specializing in real-time navigation systems for use in self-driving vehicles, robots or industrial drones, which uses a combination of satellite-based positioning systems such as GPS with computer vision technologies to achieve an unparalleled degree of prec... » read more

Bare Metal Programming


As the need for safety and security grows across application areas such as automotive, industrial, and in the cloud, the semiconductor industry is searching for the best ways to protect these systems. The big question is whether it is better to build security and safety into hardware, into software, or both. The answer isn't entirely clear yet, but one of the options under consideration is s... » read more

Silent, lightweight aircraft powered by ionic wind Instead of propellers or turbines, MIT researchers have built and flown the first-ever aircraft with no moving parts that is powered by an “ionic wind” — a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady flight.

Overcoming Gender Stereotypes In Tech


Gender inequality in the workplace is more complex and deep-rooted than most studies have shown, and efforts to address those issues are only scratching the surface. The problem runs deeper than just moving women into upper management. It extends all the way through organizations in ways that aren't always obvious. “I've been talking to senior women in engineering and junior women in en... » read more

Designing transistors that don’t overheat In order to avoid heat-induced voids and cracking that can cause chips and circuits to fail, Stanford University and University of California at Davis researchers have developed a way to not only manage heat, but help route it away from delicate devices that leverages a thermal transistor, which is a nanoscale switch that can conduct heat away from ... » read more

How To Improve Analog Design Reuse


Digital circuit design is largely automated today, but most analog components still are designed manually. This may change soon. As analog design grows increasingly complex and error-prone, design teams and tool vendors are focusing on how to automate as much of the design of analog circuits as possible. Analog design is notoriously difficult and varied. It can include anything from power ma... » read more

Deep learning device identifies airborne allergens To identify and measure airborne biological particles, or bioaerosols, that originate from living organisms such as plants or fungi, UCLA researchers have invented a portable device that uses holograms and machine learning. The device is trained to recognize five common allergens — pollen from Bermuda grass, oak, ragweed and spores from t... » read more
