System Bits: March 4


Self-completing programs Since he was a graduate student, Armando Solar-Lezama, an associate professor in MIT’s Department of Electrical Engineering and Computer Science, has been working on a programming language called Sketch -- which allows programmers to simply omit some of the computational details of their code – and then automatically fills in the gaps. If it’s fleshed out and ... » read more

Power/Performance Bits: March 4


Photon glue Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials and this effect could harness the most useful characteristics from each material for hybrid solar cells and high efficiency lighting, among other applications. To this end, researchers at the University of Michigan and Queens Coll... » read more

Reducing And Optimizing Power


While power optimization/reduction techniques such as clock gating do help engineering teams improve designs from a power perspective, more can be done. In fact, there are tools and methodologies under development to incorporate power in a more meaningful way. Part of that involves accurately pinpointing what designers should be looking for. “If you look at academia or research that has... » read more

Evolution Vs. Revolution


In the electronic design automation industry changes to tools and flows are nearly always evolutionary. They hide as much change from the user as possible, allowing easier justification from an ROI perspective, and they raise far fewer objections from users, who don’t have to spend time learning how to use new technology or rethink tried and true approaches to problems. Revolution in chip ... » read more

Is Verification At A Crossroads?


As SoC verification methodologies and technologies have continued to mature, it’s an interesting time for engineering teams as they look to meet time to market goals and cut costs in an environment of cutthroat profit margins. Whether it is hardware emulation, FPGA prototyping, virtual prototyping or traditional software simulation, each platform has its strengths and drawbacks, with overl... » read more

System Bits: Feb. 25


A faster Internet While light is capable of carrying vast amounts of information, to utilize its potential, the laser light needs to be as spectrally pure—as close to a single frequency as possible. The purer the tone, the more information it can carry. For decades researchers have been trying to develop a laser that comes as close as possible to emitting just one frequency. Today's world... » read more

SiGe chip sets speed record Researchers from IHP-Innovations for High Performance Microelectronics in Germany and the Georgia Institute of Technology have demonstrated what they say is the world's fastest silicon-based device to date. A silicon-germanium (SiGe) chip has been operated transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by abou... » read more

Many Stresses Impact TSVs


Too much stress in humans is typically not beneficial, and the same goes for 3D-ICs with through-silicon vias (TSVs). Stress effects here come from the fact that copper, which is the conductor of choice for the TSVs, and silicon have different coefficients of thermal expansion. “If you can imagine that a via will be etched through the silicon, copper will be deposited inside and then t... » read more

Power/Performance Bits: Feb. 18


Outperforming copper Carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass -- on a pound-per-pound basis -- according to new research. While individual nanotubes are capable of transmitting nearly 1,000 times more current than copper, the same tubes coalesced into a fiber using other technologies fail l... » read more

Is my iPad making me sick? If you’ve ever felt sick or queasy after using a mobile device for an extended period of time, researchers from the University of Minnesota, believe they know why. In a recent study, participants played video games on iPads - under controlled, experimental conditions - and experienced motion sickness almost a third of the time. The risk of motion sickness was fo... » read more
