Dealing With New Bottlenecks


By Ed Sperling While the number of options for improving efficiency and performance in designs continues to increase, the number of challenges in getting chips at advanced process nodes out the door is increasing, too. Thinner wires, routing congestion, more power domains, IP integration and lithography issues are conspiring to make design much more difficult than in the past. So why aren�... » read more

The Green500 And The Charge Towards Exascale Computing


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 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

Intel Vs. Everyone Else


A report from ABI Research is starting to gain some attention. For cynics, the question of why now seems perfectly reasonable, considering the report was released early last month and promptly fell well under the semiconductor industry’s radar. But cynicism aside, it’s still interesting to compare specs for chips using ARM’s Cortex-A15, A9 and Qualcomm’s ARM-based Krait. The bottom ... » read more

The Week In Review: July 8


By Mark LaPedus Fab tool vendors this week will gather at the annual Semicon West trade show in San Francisco. The mood is expected to be both gloomy and upbeat, at least based on one new and mixed forecast. The semiconductor equipment market is projected to fall 7.4% in 2013, but it will grow 27.1% in 2014, according to VLSI Research. The forecast for semis is up 10% in 2013 and 8.3% growth i... » read more

Experts At The Table: SoC Prototyping


By Ann Steffora Mutschler System-Level Design sat down to discuss SoC prototyping with Hillel Miller, pre-silicon verification/emulation manager at Freescale Semiconductor; Frank Schirrmeister, group director, product marketing, for the system development suite at Cadence; and Mick Posner, director of product marketing at Synopsys. What follows are excerpts of that conversation. SLD: How... » read more

New Reliability Issues Emerge


By Ed Sperling Most consumers define reliability by whether a device turns on and works as planned, but the term is becoming harder to define as complexity increases and systems are interconnected. Adding more functionality in less space has made it more difficult to build complex chips, and it has made it more difficult to prevent problems in those chips. Verification coverage is a persist... » read more

Inside A 450mm Metrology Consortium


By Mark LaPedus Semiconductor Manufacturing & Design sat down to discuss 450mm metrology challenges with Menachem Shoval, a former manufacturing executive at Intel and chairman of the Metro450 consortium. The Israeli-based consortium is developing metrology technology for the next-generation, 450mm wafer size. The group consists of Intel, Applied Materials, Jordan Valley, Nanomotion, Nov... » read more

Consortium Mania Sweeps 450mm Landscape


By Mark LaPedus In the mid-1990s, the semiconductor industry embarked on a costly and problematic migration from 200mm to 300mm wafer fabs. At the time, the 300mm development efforts were in the hands of two groups—Sematech and a Japanese-led entity. The equipment industry was on the outside looking in. And as a result, the migration from 200mm to 300mm fabs was out of sync and a nightma... » read more
