There Can Be Only One
By Synopsys - 14 Mar, 2013 - Comments: 0

By Cary Chin The tagline of the 1986 fantasy film “Highlander” implies that, at least in some instances, we eventually will arrive at a single, best solution for our problems. In the case of low-power design, the most obvious application of the phrase is in the standardization of low power intent formats, where the Unified Power Format (UPF) and the Common Power Format (CPF) have been lock... » read more

Shock Value
By Norman Chang - 14 Mar, 2013 - Comments: 0

By Norman Chang Chip-Package-System (CPS) ESD simulation enables system-wide ESD robustness validation, a common challenge in automotive and aerospace applications. To enable CPS ESD analysis requires an accurate chip electrostatic discharge (ESD) model and a comprehensive system-level ESD methodology. Using an accurate ESD chip model provides the following three benefits. First it helps de... » read more

Are You A Disrupter?
By Ann Mutschler - 14 Mar, 2013 - Comments: 0

I read a fascinating article recently about how to be a disrupter and how to avoid being disrupted. It goes through the characteristics of a disrupter such as: unencumbered development, unconstrained growth, new product cycles and undisciplined strategy. It also gives the example of how the standalone GPS unit market tanked in a matter of two weeks once smartphone mapping apps became availab... » read more

Leakage Optimization
By Arvind Narayanan - 24 Feb, 2013 - Comments: 0

By Arvind Narayanan For consumer electronics such as cell phones, tablets, and laptops, long battery life is a key requirement. Battery life is directly related to total power consumption—which is a function of switching activity, capacitance, and voltage—across all operational modes. In full active mode on a cell phone, for example, the dynamic power that comes from signal switching is hi... » read more

28nm Powers TSMC Forward
By Barry Pangrle - 14 Feb, 2013 - Comments: 1

By Barry Pangrle TSMC’s financial results for Q4 of 2012 and for the full year were announced just a few weeks agom with TSMC stating it had achieved record sales and profits. Basically, TSMC currently owns the 28nm foundry market. Chairman Morris Chang was clear to distinguish 28nm from 32nm. TSMC substantially moved to the 40nm “half-node” from 45nm, and then skipped 32nm and went to 2... » read more

Uncommon Goals
By Atrenta - 14 Feb, 2013 - Comments: 0

I had the opportunity to attend the Common Platform event recently. This is a technology and business showcase sponsored by Global Foundries, IBM and Samsung with major support from ARM, Cadence, Synopsys and Mentor. Wow, that’s some serious sponsorship. The event was well run and provided a good balance of technology details and business outlook. The wine at the evening reception was decent ... » read more

Big Rocks First
By Synopsys - 14 Feb, 2013 - Comments: 0

By Cary Chin Up on the wall in the hallway by the printer at my office, there’s an article by a management consultant entitled, “PUT THE BIG ROCKS IN FIRST!” It describes the demonstration that has been conducted and described many times by many consultants and motivational speakers over the years. Starting with an empty bucket, place large rocks in the bucket until it is full. Repeat by... » read more

Clean Your Clock
By William Ruby - 14 Feb, 2013 - Comments: 0

Lowering power consumption seems to be on every designer’s mind these days. And yet when asked about applying low-power design techniques, many engineers respond, “Well, we do clock gating ... and that’s about it.” Clock gating is low-hanging fruit when it comes to low-power design. Clock gating is also well automated, as witnessed by capabilities in modern logic synthesis tools. The... » read more

Thermal On My Mind
By Ann Mutschler - 14 Feb, 2013 - Comments: 0

Oh heat, how I miss thee… in the dead of winter of course. And while heat is a good thing for my garden, it’s not so great when it comes to my, your and everyone’s electronic devices. I’ve been reflecting a lot on this topic since researching thermal management for my article, “Too Hot To Handle.” You see, I have a favorite laptop. It’s a MacBook Pro with a nice, large screen a... » read more

Guidelines For Designing Multi-Voltage ICs
By Arvind Narayanan - 17 Jan, 2013 - Comments: 0

By Arvind Narayanan Multi-voltage designs are increasingly common in ICs for mobile devices, but can be difficult to implement. The design flows for multi-voltage architectures are inherently complex and present many new challenges because many blocks are either operating at different voltages or are shut down intermittently. Multi-threshold CMOS switches enable switching off certain portio... » read more
