Accuracy Is Relative
By Ann Mutschler - 11 Aug, 2016 - Comments: 0

I've been doing some thinking on the concept of accuracy lately in my article, Does Power Analysis Need To Be Accurate? And, I’ve come to the conclusion that there isn’t a single conclusion to be had. Accuracy is very relative to the task at hand, as well as the use case, and the very specific power requirements. And maybe the focus shouldn't be always on the accuracy, but on what the chan... » read more

Back To Basics On Multi-Voltage Verification
By Srikanth Jadcherla - 11 Aug, 2016 - Comments: 0

It has been more than a decade since the paradigm of voltage-aware Booleans came about and the world of multi-voltage verification took off. We started with 3-5 island SoCs and now stare at 300+ islands on a single SoC. While we have a well-developed standard (IEEE 1801/UPF) for the expression and analysis of voltage variation, it is apt to not forget some of the basics and see how they will ca... » read more

The Role Of Energy-Efficient Circuits In Wearable Healthcare Applications
By Christine Young - 11 Aug, 2016 - Comments: 0

As beneficial as they are, health monitors for conditions like high blood pressure, arrhythmia, and epilepsy can be uncomfortable and inconvenient due to all of their protruding wires. This opens up an opportunity for designers of wearable healthcare applications. “Wearable electronics are needed for proactive healthcare,” said Dr. Jerald Yoo, an associate professor in the Department of ... » read more

Confronting Design Challenges With Smaller Thermal Envelopes
By James Bruce - 11 Aug, 2016 - Comments: 0

For design engineers, physics giveth but physics can also taketh away. Consider leading-edge smartphones. Outside the improved performance that each generation gives consumers, the handsets themselves get thinner, sleeker, lighter. The reduction in the Z height is effectively a given with each new generation. In 2010, the HTC Nexus One was 11.5mm thick; this year, the Mate 8 is 7.9mm. Rem... » read more

Optimizing Emulator Utilization
By Russell Klein - 11 Aug, 2016 - Comments: 0

The growing pressures of market schedules, design complexity and the ever-increasing amount of embedded software in today’s SoCs has put verification in the hot-seat. Now that new emulation tools can link hardware and software verification, SoC designers are turning to emulation more than ever before to debug embedded software. The standard method for debugging software with an emulator is wi... » read more

Architecting Memory For Next-Gen Data Centers
By Frank Ferro - 26 Jul, 2016 - Comments: 2

The industry’s insatiable appetite for increased bandwidth and ever-higher transfer rates is driven by a burgeoning Internet of Things (IoT), which has ushered in a new era of pervasive connectivity and generated a tsunami of data. In this context, datacenters are currently evaluating a wide range of new memory initiatives. All seek to optimize efficiency by reducing data transport, thus sign... » read more

Energy-Efficient Design Helps Autonomous Vehicles Take Off
By Margaret Schmitt - 18 Jul, 2016 - Comments: 1

A new flight endurance record was set recently by the Predator B/MQ-9 Reaper Big Wing experimental drone, traveling 37 hours non-stop, and setting the bar for the next stage of autonomous flight development. The growth of drone technology and their autonomous capabilities for surveillance, security, and reconnaissance has grown rapidly over the past several years, thanks to ever-increasing perf... » read more

Power Confounds, Challenges
By Ann Mutschler - 14 Jul, 2016 - Comments: 0

I have to admit I’m always surprised to hear that design teams are not using tools to the fullest extent possible, leaving valuable power saving opportunities on the table, until I remember how daunting it is to get it all right without tremendous experience, expertise, and the right tools. I’m also always fascinated to learn about less-obvious effects from power. To this point, Aveek... » read more

Better PMIC Design Using Multi-Physics Simulation
By Karthik Srinivasan - 14 Jul, 2016 - Comments: 1

Energy efficiency and thermal management are gaining importance in the IC and system design community. Because the integrated circuit is the major source of power consumption and hence heat dissipation, semiconductor companies are under immense pressure to reduce the overall power envelope of the IC that goes into the system. This phenomenon is seen globally, irrespective of whether the chip... » read more

Designing Power-Efficient, Implantable Medical Devices
By Christine Young - 14 Jul, 2016 - Comments: 0

Medical devices used for treatment traditionally tend to be big, bulky, and full of wires, making them uncomfortable or inconvenient for the patient to use. For Dr. Rikky Muller and Cortera Neurotechnologies, power-efficient, implantable medical devices provide a viable alternative. Muller is an assistant professor of electrical engineering and computer sciences at UC Berkeley. She is also a... » read more
