More Efficient Things
By Qi Wang - 11 Jul, 2013 - Comments: 0

By Qi Wang There are many angles to consider when it comes to efficiency and the Internet of Things (IoT). At the architectural level, the IoT system consists of connected things, the networks and the cloud servers for massive data processing. Efficient data storage and servers means lower power consumption, which will result in millions of dollars in savings. For the connected things thems... » read more

SEMICON Season And The DAC Dilemma
By Atrenta - 11 Jul, 2013 - Comments: 0

By Mike Gianfagna Amid great fanfare and excitement, SEMICON West started this week. While not as old as DAC (43 years for SEMICON vs. 50 years for DAC), it is a broad and ambitious conference. Billed as “the flagship annual event for the global microelectronics industry,” the conference treats topics such as: Wow, that phrase it taken directly from a SEMCON West email blast, and ... » read more

RTL Design-for-Power In Mobile SoCs
By Preeti Gupta - 11 Jul, 2013 - Comments: 0

If you are one of the more than 2 billion smartphone users today, it is hard to imagine life without one! Breaking new frontiers, wearable smart devices and the Internet of things are the latest buzz. Mobile system-on-chips (SoCs) continue to clock faster and pack more functionality, yet are required to consume lower power for battery life and thermal considerations. Power consumption is a k... » read more

To DVFS Or Not To DVFS
By Ann Mutschler - 11 Jul, 2013 - Comments: 0

I’m in a great position to hear lots of interesting opinions about technology today and this week was no different. During a discussion with Atrenta CTO Bernard Murphy about power and performance tradeoffs, he mentioned that he is not hearing a lot of engineering teams using DVFS (dynamic voltage and frequency scaling) because it creates complications for clock synchronization and makes the d... » read more

Electromigration Analysis At Advanced Nodes
By Valeriy Sukharev - 11 Jul, 2013 - Comments: 0

Introduction Continuous downward scaling is challenging electromigration (EM) signoff using traditional EM checking approaches. The size reduction of metal line cross sections results in higher current densities, which are governed by technology scaling. With the transition to advanced technological nodes, the widely-predicted decrease in EM lifetime is responsible for the pessimistic performa... » read more

Power Grid Analysis
By Marko Chew - 13 Jun, 2013 - Comments: 1

By Marko Chew Introduction Power grids (PGs) have consumed an increasingly larger percentage of routing resources in recent process node generations, due to lower maximum current limits imposed by the foundry. It is not uncommon to see upwards of 30% of the routing resources consumed by the PG, with correspondingly negative implications for a design’s routability. Of course, the design’... » read more

Life In A Connected World
By Qi Wang - 13 Jun, 2013 - Comments: 0

By Qi Wang At this year’s DA, we heard a lot of discussions on the Internet of Things. Gregg Lowe, CEO of Freescale, said in his keynote speech that by 2020 there will be 50 billion connected devices. Considering there are an estimated 4 billion devices in the world now, mostly unconnected, this represents huge growth potential for the semiconductor industry because each device will have at ... » read more

New Standard!
By Barry Pangrle - 13 Jun, 2013 - Comments: 0

It’s been a little over four years since the first IEEE 1801 standard was officially published in March 2009, but the standard can trace its roots back to years before that date. On May 30th, the IEEE released a press announcement for the newest version of the standard, IEEE 1801-2013 (a.k.a. UPF 2.1). It takes a considerable amount of effort and attention to detail to produce a solid standar... » read more

Challenges In IC And Electronic Systems Verification
By Aveek Sarkar - 13 Jun, 2013 - Comments: 0

In the first two parts of this series, we reviewed the challenges design teams face as they grapple with increasing power consumption, tighter schedules and the drive to reduce costs. Both a top-down and a bottom-up analysis framework were proposed to help control these challenges. In part 2 of this series, specific challenges were outlined including power budgeting, power and signal integrity,... » read more

Apple’s Big Breakthrough
By Synopsys - 13 Jun, 2013 - Comments: 0

By Cary Chin For literally years now, we’ve talked about and measured energy consumption as smartphones have morphed from primarily communications devices (voice), to the world’s most widespread computing platform, and back again to a communications focus. But this time it’s data communications, and voice calls are just a small subset. Smartphones themselves, once the defining standar... » read more
