What’s Next For Power Optimization


Today it is difficult to find a design that does not consider some kind of power optimization. Mobile needs it to preserve battery life, data centers need it to reduce operating cost, and many are finding they need it to meet tougher regulatory requirements. In a survey conducted two years ago, there was no segment of the industry that was not taking a serious look at reducing their power profi... » read more

New Challenges Emerge With FinFETs


Working at advanced process nodes is always tricky. There are new things to worry about and more rules to deal with initially, yet the promised benefit is improved performance, power and area, or cost. But at the next process node, and the one after that, there are so many variables coming into play that trying to make sense of the PPA equation is becoming much more difficult. Early reports ... » read more

Thermally Challenged


Chips run hot and the thermal densities increase with every reduction in fabrication geometry. “When we go down to 16nm the local power density increases by 25% and the local gate density also increases by 25% to 30%,” explains Norman Chang, vice president of product strategy at Ansys/Apache. In fact, this is becoming such a large problem that it is affecting the scaling process itsel... » read more

Seven Ways To Improve PPA Before Moving To FinFETs


Henry Ford wrote in his autobiography, “Any customer can have a car painted any color that he wants so long as it is black.” And for decades, the semiconductor industry has marched to a similar theme set by Moore’s Law. But with the transition to finFETs harder than it first appeared, questions are beginning to pop up that is fueling a new level of confusion. While the growing list of... » read more

Powerful Software Optimization


It is commonly accepted that the higher you go in the design chain, the bigger the impact that design and implementation decision can have. While power optimization may have started deep in the silicon, the success of a product, such a smart phone, often is based on the time between charges. Batteries provide a finite energy resource, and while low-level optimization may focus on power reductio... » read more

Big Changes Rock Global Smartphone Market


BANGKOK — One of the many draws for Western travelers here in Thailand and throughout much of Asia, including China, is the availability of cheap consumer electronics. Unfortunately many of these electronic goods — little-known off-brands mimicking better-known counterparts, or white-label devices being passed off as name-brand products to unsuspecting consumers — typically are technologi... » read more

Is There Light At The End Of Moore’s Tunnel


Electrons are slow, clumsy and quite easily distracted. They’re slow because it now takes a signal longer to cross a chip than the period of the clock signal. They often don’t travel in straight lines as they collide with other atoms. And electromagnetic interference between adjacent signals can mess with the information they are transferring. On the other hand, light has none of these p... » read more

Even Standard IP Isn’t Always Standard


Time to market and rising complexity are forcing the use of more third-party IP as well as increasing reuse of internally developed IP. But as more IP is added into SoCs, chipmakers are discovering some interesting things: Not all IP works together as planned, even when it’s well characterized. As with cars, performance and mileage vary greatly depending upon who’s driving—and who’s... » read more

Do Students Need More Formal Education?


A few weeks ago, some of the top researchers and practitioners in the area of formal methods converged on Portland, Oregon. The event was the annual Formal Methods in Computer-Aided Design (FMCAD) conference and Semiconductor Engineering attended the panel titled “Teaching Formal Methods: Needs, Challenges, Experiences, and Opportunities.” Panelists included: Jason Baumgartner, formal verif... » read more

Experts At The Table: What’s Next?


Semiconductor Engineering sat down with Jim Hogan, long-time industry venture capitalist; Simon Bloch, senior director at Samsung Electronics; Sumit DasGupta, formerly Si2 senior vice president of engineering; and Mike Gianfagna, vice president of marketing at eSilicon (VP of corporate marketing at Atrenta when this roundtable was held). What follows are excerpts of that discussion. SE: What... » read more
