7nm Power Issues And Solutions


Being able to achieve 35% speed improvement, 65% power reduction and 3.3X higher density makes adopting a 7nm process for your next system-on-chip (SoC) design seem like an easy decision. However, with $271 million in estimated total design cost and 500 man-years it would take to bring a mid-range 7nm SoC to production, companies need to carefully weigh the benefits against the cost of designin... » read more

The Time Dimension Of Power


Power is the flow of energy over time. While both aspects of that equation are important, they are important to different people in different ways. Energy that moves too quickly can cause significant damage. Too much energy moving over time can mean a non-competitive product, from battery-powered devices to a wide array of locations such as the datacenter. When the industry talks about power... » read more

Can Low-Power Devices Be Secure?


Successfully designing a low-power, high-performance chip design is an accomplishment, but effectively implementing cybersecurity in such devices makes it much more difficult. Safety, particularly functional safety for automotive and military/aerospace applications, also can be a prime concern in creating low-power, high-performance integrated circuits and systems. When combined with securit... » read more

Three Power-Saving Techniques Using PCI Express IP


The increasing data traffic between devices in a computing application environment is causing a large power footprint, and for that reason designers are looking for ways to lower the power consumption of their SoCs during sparse or idle times. The smaller, battery-powered devices are often idle and in deep sleep modes, but these deep power saving modes come at the cost of slow resume times to s... » read more

Saving Energy In The Fab


It’s not an exaggeration to say that integrated circuits are a critical component of any effort to reduce global carbon dioxide emissions. The most efficient engines depend on microcontrollers to optimize fuel consumption. Global shipping uses sophisticated simulators for load balancing and route planning. Computing power that once needed room-sized cooling units now fits in a battery-powered... » read more

Tech Talk: Earlier Software


Malte Doerper, senior manager of product management at Synopsys, talks about the big "shift left" for software, where the problems crop up, and how to save as much as a year of development time with automation and better methodologies. [youtube vid=BjmHE0AvUIA]   Related Stories Bridging Hardware And Software The need for concurrent hardware-software design and verification is i... » read more

Silicon Photonics Comes Into Focus


Silicon photonics is attracting growing attention and investment as a companion technology to copper wiring inside of data centers, raising new questions about what comes next and when. Light has always been the ultimate standard for speed. It requires less energy to move large quantities of data, generates less heat than electricity, and it can work equally well over long or short distances... » read more

Emulation’s Footprint Grows


It wasn't that many years ago that [getkc id="30" comment="emulation"] was an expensive tool available to only a few, but it has since become indispensable for a growing number of companies. One obvious reason is the growing size of designs and the inability of [getkc id="11" kc_name="simulation"] to keep up. But emulation also has been going through a number of transformations that have made i... » read more

Power/Performance Bits: Oct. 25


Energy-harvesting floor Engineers at the University of Wisconsin-Madison developed a flooring material which can be used as a triboelectric nanogenerator to convert footsteps into electricity. The method uses wood pulp, a common waste material already often used in flooring. The pulp is partly make of cellulose nanofibers, which when chemically treated produce an electrical charge when th... » read more

OLEDs Shine In Phones, TVs, Lights


OLEDs are coming—everywhere. While the new iPhone 7 models do not have organic light-emitting diode (OLED) displays, those handsets are likely to be the last Apple will offer before it makes the smartphone transition to OLED displays next year. The Apple Watch, however, does have a flexible OLED display with a sapphire crystal cover or an Ion-X glass cover, and the Apple Watch Series 2 ... » read more
