Getting The Power/Performance Ratio Right


Getting to market quickly means determining as soon as possible if a concept for a new design will work or not, particularly where power and performance are concerned. Making this determination requires intimate knowledge of the scenarios in which the device will operate — and that is just the start. In order to set things up, you need to somehow model the system, which could be done in a ... » read more

Early Power Modeling Using SystemC And TSMC System-PPA


Power consumption is often more important than performance in today’s SoC designs because of battery size and power dissipation limitations. The dilemma is that the most leverage available to optimize power consumption is at the architectural design stage, but there often is not enough information available early enough to make accurate power decisions. On the performance side, SystemC mod... » read more

Power Options And Issues


In the quest to get SoC power right as early as possible in the design flow, it still holds true that the biggest impact occurs at the beginning of the project, with diminished results as a design progresses through the flow toward tapeout. [getentity id="22186" e_name="ARM's"] big.LITTLE architecture has gained a lot of traction here, prompting MediaTek to introduce its Tri-Gear big.Medium.... » read more

Reaching The Power Budget


Everything related to power in chip design today is a big deal—and it’s just getting bigger. Meeting the power budget is becoming harder at each new node, but it's also becoming difficult in a number of new application areas at existing nodes. That's a big problem because [getkc id="108" kc_name="power"] is now considered a competitive advantage in many markets. It's also one of the most... » read more

2.5D Becomes A Reality


Semiconductor Engineering sat down to discuss 2.5D and advanced packaging with Max Min, senior technical manager at [getentity id="22865" e_name="Samsung"]; Rob Aitken, an [getentity id="22186" comment="ARM"] fellow; John Shin, vice president at [getentity id="22903" e_name="Marvell"]; Bill Isaacson, director of ASIC marketing at [getentity id="22242" e_name="eSilicon"]; Frank Ferro, senior di... » read more

Are Models Always The Answer?


Given the shift to system level design and the need to make tradeoffs early in the design process, much emphasis is placed on modeling, and for good reason. Tobias Bjerregaard, CEO of Teklatech reminded that power integrity analysis and signal integrity analysis evolved to be more or less a checkmark from many companies. “They run it and then say, ‘OK, it is fine,’ but they don't think... » read more

What’s Next for System-Level Power Modeling?


Availability of models and libraries has long been one of the biggest barriers to the adoption of new EDA tools and methodologies, whether due to the investment needed to create these models and libraries or because of the “at-risk” nature of developing complex models in proprietary formats. With the approval of UPF3.0 (IEEE 1801-2015) this past December, we now have an industry standar... » read more

Why Power Modeling Is So Difficult


Power modeling has been talked about for years and promoted by EDA vendors and chipmakers as an increasingly important tool for advanced designs. But unlike hardware and software modeling, which have been proven to speed time to market for multiple generations of silicon, power modeling has some unique problems that are more difficult to solve. Despite continued development in this field, po... » read more

Shift In Focus For Low Power Design


The increased levels of interest we have seen over the last couple of years in system-level power modeling and energy-aware system-level design methodology, coupled with broad participation in the associated industry standard activities around system level power, gives us a clear indication that a shift in focus for low-power design is taking place. Our attempts to deliver energy-efficient high... » read more

What To Do With Power Models


Ask any design engineer if they want a power model, and you can guess the answer. As far as what they want to use it for, the answer will vary. When I asked Jem Davies, ARM Fellow, if OEM engineering teams want a comprehensive power model, he said, “Ideally, yes. Perfectly ideally, what they would like to have from us is a model of each individual block of our IP which plugs together in a ... » read more
