Supporting LP In New Process Nodes
By Ann Mutschler - 10 Jul, 2014 - Comments: 0

Manufacturing process nodes and EDA tools are advancing all the time, but not always utilized at the same pace. And from a tools perspective, there are challenges to supporting low power in new process nodes while maintaining and improving the existing process nodes. One way design teams address this is by leveraging the most advanced software on the less-than-bleeding edge designs. To th... » read more

Solar State Of Mind
By Ann Mutschler - 10 Jul, 2014 - Comments: 1

The dog days of summer seem an appropriate time to ponder all things solar while trying to stay cool. To this end, it’s rather encouraging to note more states are embracing solar as part of their energy mix and even the White House takes advantage of it. I was curious to know if there was a map of solar installations in the U.S., and sure enough, I found an interactive one on the website for ... » read more

Power/Performance Bits: July 8

In an advance that could one day enable the miniaturization of laser systems, researchers at the University of Texas at Austin and the Technical University of Munich have developed a new nonlinear metasurface, or meta mirror. The researchers call their invention a “nonlinear mirror,” which they believe could help advance nonlinear laser systems that are used for chemical sensing, explosi... » read more

Carbon nanotubes “unzipped” into graphene nanoribbons by a chemical process invented at Rice University are finding use in all kinds of projects, but Rice scientists have now found a chemical-free way to unzip them. A Rice materials scientist discovered that nanotubes that hit a target end first turn into mostly ragged clumps of atoms, but nanotubes that happen to broadside the target un... » read more

Rethinking Encryption
By Ann Mutschler - 07 Jul, 2014 - Comments: 0

With security experts working around the clock to beat the hackers, because the hackers are doing the very same thing to beat the security experts, it doesn’t come as much of a surprise to learn that researchers at European university EPFL have cracked a so-called “unassailable encryption algorithm” in just two hours. It turns out, a protocol based on allegedly tamper-proof “discrete... » read more

System Bits: July 1

In the quest to build gadgets that can survive the abuse, engineers have been testing electronic systems based on new materials that are both flexible and switchable – that is, capable of toggling between two electrical states: on-off, one-zero, the binary commands that can program all things digital. At the same time, three Stanford researchers believe that they’ve discovered just such ... » read more

Cheap, rechargeable, organic Intended for use in power plants and intend to make the energy grid more resilient and efficient, USC researchers have developed a water-based organic battery that is long lasting and built from cheap, eco-friendly components. The new battery, which uses no metals or toxic materials, is intended for use in power plants, where it can make the energy grid more resili... » read more

Asynchronous Is Mostly Academic
By Ann Mutschler - 26 Jun, 2014 - Comments: 4

There are a number of interesting technologies to keep an eye on in term of how and when they could be adopted for use in SoC design today, some of which include gallium arsenide, GPGPUs, 3D ICs and asynchronous logic. Asynchronous logic promises a number of benefits in some specific application areas, and one that buoys to the surface for potential near-term use is in the area of security a... » read more

Where Do We Stand With CDC?
By Ann Mutschler - 26 Jun, 2014 - Comments: 1

Semiconductor Engineering sat down to discuss where the industry stands on clock domain crossing with Charlie Janac, CEO of Arteris; Shaker Sarwary, VP of Formal Verification Products at Atrenta; Pranav Ashar, CTO at Real Intent; and Namit Gupta, CAE, Verification Group at Synopsys. What follows are excerpts of that conversation. SE: While not a new aspect of design, clock domain crossing is... » read more

System Bits: June 24

Experimental 36-core chip The more cores — or processing units — a computer chip has, the bigger the problem of communication between cores becomes. For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical Engineering and Computer Science at MIT, has argued that the massively multicore chips of the future will need to resemble little Internets, where each core has an associ... » read more
