System-Level Power Modeling Takes Root


Power, heat, and their combined effects on aging and reliability, are becoming increasingly critical variables in the design of chips that will be used across a variety of new and existing markets. As more processing moves to edge, where sensors are generating a tsunami of data, there are a number of factors that need to be considered in designs. On one side, power budgets need to reflect th... » read more

Does Power Verification Work?


Functional verification continues to evolve, but power verification—a somewhat new concern—remains at levels of sophistication reminiscent of functional verification 30 years ago. When will power verification catch up and what must to happen to make it possible? These are questions that the industry is still grappling with, and not everyone believes they require answers. Functional error... » read more

Power Challenges At 10nm And Below


Current density is becoming much more problematic at 10nm and beyond, increasing the amount of power management that needs to be incorporated into each chip and boosting both design costs and time to market. Current per unit of area has been rising since 90nm, forcing design teams to leverage a number of power-related strategies such as [getkc id="143" kc_name="dynamic voltage and frequency... » read more

Closing The Loop On Power Optimization


[getkc id="108" kc_name="Power"] has become a significant limiter for the capabilities of a chip at finer geometries, and making sure that performance is maximized for a given amount of power is becoming a critical design issue. But that is easier said than done, and the tools and methodologies to overcome the limitations of power are still in the early definition stages. The problem spans a... » read more

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
