Power Shifts In Digital Chip Space
By Bhanu Kapoor - 08 Aug, 2013 - Comments: 0

By Bhanu Kapoor The power issue has been quite disrupting in the digital semiconductor space. The processor architecture shifted to parallel processing with the “power wall” stopping the frequency scaling that the industry had conveniently used in the last few decades. The power issue also is causing semiconductor process technology to change in ways other than simply scaling from one ... » read more

Chips And EDA: The Day After Tomorrow
By Atrenta - 08 Aug, 2013 - Comments: 0

By Mike Gianfagna Summer blockbuster movie season is in full swing, and there’s a lot of science fiction content musing about what the future will look like. That got me thinking about what a “Day After Tomorrow” movie that dealt with EDA and the semiconductor supply chain might look like. OK, no studio is going to pick up this story, I get it. But for those of us in this business, the p... » read more

Next-Gen Distributed Machine Processing
By Rama Nemalikanti - 08 Aug, 2013 - Comments: 0

By Rama Nemalikanti The gate count increase of chip designs, especially for mobile application processor system-on-chips (SoCs), is being closely tracked to help guide the development of supporting design and simulation tools. However, sign-off quality power integrity analysis requires the inclusion of the entire integrated circuit (IC) design, along with its associated package and printed cir... » read more

Security And Convergence
By Ann Mutschler - 08 Aug, 2013 - Comments: 0

I’ve had a lot on my mind the past few weeks while reporting on seemingly disparate topics like the Internet of Things, embedded software and hardware accelerators, but in the world today, these things are really tightly connected, actually. They all boil down to convergence and security in my mind. Looking at the Internet of Things (IoT), which promises to connect all of us and all of our... » read more

Delicate Balance
By Joseph Hupcey III - 08 Aug, 2013 - Comments: 0

By Joe Hupcey III It’s not surprising that power optimization is a critical part of today’s complex designs. Unbeknownst to most consumers is an underlying methodology that every design engineer must follow to make sure a consumer device meets the power requirements of the consumer—even if the consumer doesn’t realize they’re demanding it. The situation in industrial products, suc... » read more

Material Impact
By Barry Pangrle - 08 Aug, 2013 - Comments: 0

Ed Sperling’s June article New Approaches to Better Performance and Lower Power took a look at the new materials that researchers are examining for future technology nodes. Figure 1. Basic Planar CMOS FET Figure 1 shows a basic diagram of a planar CMOS FET (diagrams for other FETs can be found here). The drive strength of a FET is proportional to , where μ is the surface mobility for... » read more

EM Analysis At Advanced Nodes
By Valeriy Sukharev - 26 Jul, 2013 - Comments: 0

Going forward, a very different method of EM assessment can be proposed if we look at interconnect reliability from the position of its functionality, when the failure of the interconnect means its inability to function properly. The two most important functions of the chip interconnect are: Providing connectivity between different parts of design for proper signal propagations (signal circ... » read more

EM Analysis At Advanced Nodes
By Valeriy Sukharev - 19 Jul, 2013 - Comments: 0

EM statistics Almost 50 years ago, James Black demonstrated experimentally that TTF of the metal line stressed by direct current (DC) of density j at the temperature T follows the dependency where k is the Boltzmann constant, and A is the proportionality coefficient, which can depend on line geometry, residual stress, and temperature. Two critical parameters, the current density exponen... » read more

The Green500 And The Charge Towards Exascale Computing
By Barry Pangrle - 11 Jul, 2013 - Comments: 0

The latest Green500 list (Excel spreadsheet here) was just released at the end of June, and heterogeneous systems continue to dominate the top of the list with the new leader besting the old by nearly 30%. Two systems using Intel Xeon E5-2687W 8-Core 3.1 GHz processors coupled with NVIDIA K20’s topped the list. Eurotech’s Eurora and Aurora Tigon both broke the 3,000 MFLOPS/W barrier, record... » read more

MacBook Air 2013: Power Efficient To The Core(s)
By Synopsys - 11 Jul, 2013 - Comments: 0

By Cary Chin Last month, we looked at the initial announcement at WWDC of the latest MacBook Air laptops. These new machines are physically nearly identical to their predecessors, boast negligible performance improvements (and even performance degradation in some instances), cost about the same, and yet in my view are perhaps the most revolutionary products since the MacBook Air line was reinv... » read more
