Background
Traditionally, the interface between chip designers and system power, packaging, reliability, and mechanical engineering teams was a relatively straightforward exchange of specifications. Chip designers developed preliminary power dissipation estimates, often based on a simplifying power/mm**2 value. … Read More
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
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 in IoT edge devices gets a lot of press around how to make devices last for years on a single battery charge, 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 to support… Read More
Most of what you have read about design for low power has probably focused on mobile devices where power consumption 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 at any given … Read More
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
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
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
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&D… Read More
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
