Reflecting on the Future
By Ann Mutschler - 13 Jun, 2013 - Comments: 0

Since returning from the Design Automation Conference, I’ve been reflecting on some very interesting discussions I had last week in Austin. The ones that are sticking with me concern the old, sequential algorithms that run EDA tools today. The fact is, given design complexity, they are running out of steam. As a result, the industry is looking at possibly leveraging GPUs since they may be ... » read more

Hierarchy And Pain Management
By Bernard Murphy - 10 Jun, 2013 - Comments: 0

By Bernard Murphy Hierarchy is unavoidable for any large design. It partitions development and verification complexity into digestible chunks. It enables parallel development on different parts of a system. It promotes reuse. And it provides a graceful method to partition for implementation. And yet, there are times when hierarchy gets in the way. The biggest drawback with hierarchy is that... » read more

Smarter Clock Gating
By Various Writers - 09 May, 2013 - Comments: 0

By Ghulam Nurie With the proliferation of mobile devices, power consumption and battery life have emerged as significant concerns during chip design. There are many different techniques used for power optimization, but of all the different techniques, clock gating is the most popular and widely used technique, according to a blind, anonymous survey emailed to several thousand participants worl... » read more

BIST For Low-Power Devices
By Steve Pateras - 09 May, 2013 - Comments: 0

By Stephen Pateras The persistent growth of mobile computing is driving an increasing need to manage power consumption within semiconductor devices. This has significant implications on the design and test of these devices. Low-power requirements affect test in two separate ways. First, it’s important to ensure that any functional power constraints are met (or at least adequately managed) du... » read more

Power-Up Low-Power Verification
By Adam Sherer - 09 May, 2013 - Comments: 0

By Adam Sherer When facing low-power verification in the SoC world, everyone could use a few power-ups just like Nintendo’s little plumber, Mario. Sure, Mario could run and jump through a lot of terrain, but when he hit some new challenges he could rely on some new tools and techniques to get him through. Completing your first SoC with a single power control module (PCM) and domain is lik... » read more

Power Markets
By Barry Pangrle - 09 May, 2013 - Comments: 0

There has been an ongoing discussion in the industry about the importance of power and performance and which is more important. I submit that the real question is: How much performance can be squeezed out of the power budget for any given market segment? Figure 1. Processor Market Segment Power Budgets Figure 1 shows a rough breakdown of the different market segments for processors, alo... » read more

Does My Phone Dream?
By Synopsys - 09 May, 2013 - Comments: 0

By Cary Chin Starting with my commentary on the Tesla Model S last month (poor standby time before software update), I was thinking about how common a problem standby power is these days. Nearly all of our recently introduced smartphones have had similar problems (iPhone 5, Nexus 4, Galaxy S4, Lumia 900) running on virtually all operating systems (iOS 6.x, Android 4.2.x, Windows Phone 8). All ... » read more

DAC Is Where?
By Atrenta - 09 May, 2013 - Comments: 0

By Mike Gianfagna DAC season is upon us. I gave up counting the number of DACs I’ve attended a long time ago—when I turned 29 for the third time, I believe. This year, DAC is special in a few important ways. First of all, it’s the 50th DAC. Yes, the show has indeed been around that long. It started as a workshop with a bunch of engineers debating algorithms. For an industry that is arg... » read more

Challenges In IC And Electronic Systems Verification
By Aveek Sarkar - 09 May, 2013 - Comments: 0

Power efficiency, unrealistic schedules, and cost-down considerations are increasingly the top challenges design teams must meet to deliver next generation electronic systems, whether it is for the mobile, server, or automotive market. In addition, a successful chip tapeout does not guarantee the eventual end-product’s success—there are many variables to take into account. In the first p... » read more

A Poison Apple
By Ann Mutschler - 09 May, 2013 - Comments: 0

As I was researching ‘green’ as it relates to the world of semiconductors I recalled the big story from early 2011 about Apple’s alleged poisoning of workers in China manufacturing plants and wondered whether the situation has changed. At the same time, when I hold my iPhone in my hand, I am sadly aware that my desire for technology might have been at the cost of someone’s health. I ... » read more
