A Fresh Idea in Differential Energy Analysis

A Fresh Idea in Differential Energy Analysis
by Bernard Murphy on 09-06-2018 at 7:00 am

When I posted earlier on Qualcomm presenting with ANSYS on differential energy analysis, I assumed this was just the usual story on RTL power estimation being more accurate for relative estimation between different implementations. I sold them short. This turned out to be a much more interesting methodology for optimizing total… Read More


Creative Noise-Reduction in Automotive AMS

Creative Noise-Reduction in Automotive AMS
by Bernard Murphy on 12-12-2017 at 7:00 am

Automotive applications are one of the hottest domains today in semiconductor design. We’re bombarded daily with articles on new hybrids, electric cars, ADAS and autonomous cars, trucks and busses. All of these applications are certainly amazing, but the devices that make them work still have to deal with the same old challenges,… Read More


Power Management Beyond the Edge

Power Management Beyond the Edge
by Bernard Murphy on 01-25-2017 at 7:00 am

Power in IoT edge devices gets a lot of press around how to make devices last for years on a single battery Image Removedcharge, significantly through “dark silicon” – turning on only briefly to perform some measurement and shoot off a wireless transmission before turning off again. But we tend to forget that the infrastructure… Read More


Low Power Design – a Server Perspective (Webinar)

Low Power Design – a Server Perspective (Webinar)
by Bernard Murphy on 09-21-2016 at 7:00 am

Most of what you have read about design for low power has probably focused on mobile devices where power Image Removedconsumption constraints tend to outweigh performance objectives. These devices use aggressive power switching strategies, based on the reasonable assumption that parts or all of the device can be powered down… Read More


A Complete Simulation Platform for Mobile Systems

A Complete Simulation Platform for Mobile Systems
by Pawan Fangaria on 08-23-2015 at 7:00 am

If we take an insight into the semiconductor industry, we can easily find that mobile systems are the main drivers of this industry. The Smartphone business has remained at the top since a good number of years. Although the Smartphone sales growth has started showing a sign of stagnation, it is still a main contributor with a solid… Read More


Power Analysis Needs Shift in Methodology

Power Analysis Needs Shift in Methodology
by Pawan Fangaria on 07-26-2015 at 7:00 am

It’s been the case most of the time that until we hit a bottleneck situation, we do not realize that our focus is not at the right spot. Similar is the case with power analysis at the SoC level. Power has become equally if not more important than the functionality and other parameters of an SoC, and therefore has to be verified earlier … Read More


How PowerArtist Interfaces with Emulators

How PowerArtist Interfaces with Emulators
by Pawan Fangaria on 07-16-2015 at 5:00 pm

Last month in DAC I could see some of the top innovations in the EDA world. EDA is a key enabler for advances in semiconductor designs. Among a number of innovations worth mentioning (about which I blogged just after DAC), the integration of Mentor’s Veloce with ANSYS’ PowerArtist for power analysis of live applications caught my… Read More


Eyes Meet Innovations at DAC

Eyes Meet Innovations at DAC
by Pawan Fangaria on 06-14-2015 at 7:00 am

It gives me a very nice, somewhat nostalgic, feeling after attending the 52[SUP]nd[/SUP] DAC. There was a period during my final academic year in 1990 and my first job when I used to search through good technical papers in DAC proceedings and try implementing those concepts in my project work. In general, representation from ‘R&… Read More


Early RTL Power Analysis and Reduction

Early RTL Power Analysis and Reduction
by Daniel Payne on 03-26-2014 at 4:48 pm

Power analysis and reduction for SoC designs is a popular topic because of our consumer electronics dominated economy, and the need to operate devices on a battery source for the maximum time before a recharge. Just from my desk I can see multiple battery-powered devices: Laptop, tablet, smart phone, e-book reader, bluetooth … Read More


Mission Critical Role of Unmanned Systems – How to fulfill?

Mission Critical Role of Unmanned Systems – How to fulfill?
by Pawan Fangaria on 01-05-2014 at 11:30 am

Image RemovedDo we ever imagine what kind of severe challenges mission critical unmanned systems in air, land and underwater face? They are limited in space and size; have to be light in weight, flexible in different types of operations and at the same time rugged enough to work in extreme climatic conditions. That’s not enough;… Read More
