Wanted: ESL Power Design Flow
By Ann Mutschler - 14 Apr, 2011 - Comments: 0

In order to truly incorporate understanding of power at a higher-than-RTL level of abstraction, a new design flow is needed—and it won’t come from just one vendor. Apache believes that tool flow must contain ESL simulation, ESL synthesis to RTL along with RTL power analysis using ESL simulation results. The company maintains that this very approach has been demonstrated successfully by w... » read more

Good Times, Good People
By Atrenta - 31 Mar, 2011 - Comments: 0

I lost a long-time friend this past week. He was a member of the EDA community and so I will dedicate this blog to a discussion of the late Dr. Aaron Ashkinazy—the person, his contributions and the process for his work. The person. Aaron had a lot of friends. We’ve all been reminiscing about him this past week and some consistent comments arise. He was one of the most intelligent and kin... » read more

Quicker Turnaround
By Aveek Sarkar - 17 Mar, 2011 - Comments: 0

By Aveek Sarkar Statistics indicate the increase in sales for mobile handsets in the emerging economies will be from the sale of smart phones. According to a Nielsen report, Brazilian sales of smart phones were up 128% in 2010, compared to 2009. These emerging economies have traditionally been served by standard cell phones that provided voice and texting needs (Fig. 1), but the consumers i... » read more

Core Power
By Barry Pangrle - 17 Mar, 2011 - Comments: 0

By Barry Pangrle What type of core should I choose if I want to be really power-efficient? That’s an interesting question. The answer that a lot of people will hate to hear is that it depends. Probably the first question that needs to be answered is, what does power-efficient mean to you and how power-efficient do you really want to be? Most people can’t wait forever for a result to be ... » read more

Fast LP Simulation
By Luke Lang - 17 Mar, 2011 - Comments: 0

By Luke Lang What are the most important features of a logic simulator? I’m sure there have been lots of surveys done for this question. Unfortunately, I can’t find any results on Google. Nevertheless, I would be willing to bet that fast performance is at or near the top of every verification engineer’s wish list. For the low-power verification engineers, fast performance is also a ke... » read more

Design For Configurability
By Ann Mutschler - 17 Mar, 2011 - Comments: 0

I admit it was a bit of a surprise to me to hear from a leading IP provider of the missteps that still befall design teams today as they seek to reuse IP, but it’s a little like rubbernecking. How do you not look? According to Grant Martin, chief scientist at Tensilica, “The biggest thing that people still don’t think about at the beginning of designing some new function is designing i... » read more

Chip Failure? Don’t Worry About It!
By Ron Craig - 24 Feb, 2011 - Comments: 0

By Ron Craig Here in the United States it’s tax time again. Along with every other loyal taxpayer, I’ve been working on identifying every conceivable deduction I can think of to minimize my overall tax burden. I’m not an expert on tax law, but as far as I can tell I still can’t take advantage of the non-tax deductible dependents we like to call ‘the cats.’ Our own demanding hous... » read more

Chip-Package-System Co-Design
By Matt Elmore - 10 Feb, 2011 - Comments: 0

By Matt Elmore This year’s DesignCon 2011 featured a multitude of advanced topics pertaining to IC design. One topic that came up repeatedly was chip-package-system (CPS) co-design. In each area of application, from mobile to automotive, IC designers have prioritized the need to analyze the chip, package, and PCB as complete system, rather than independent projects. The old days of margins, ... » read more

Power vs. Accuracy
By Barry Pangrle - 10 Feb, 2011 - Comments: 0

By Barry Pangrle So, how much energy are you willing to expend to be accurate? The question is one that chip designers face more often than they probably realize. The first question really is, ‘How accurate do you need to be?’ Whether it is test coverage, verification coverage, signal-to-noise ratio, or error-correcting codes, the list is seemingly endless. Variability in the environmen... » read more

Tough Road Ahead For Small IP Vendors
By Bhanu Kapoor - 10 Feb, 2011 - Comments: 0

By Bhanu Kapoor The IP business is a difficult one. The vendors who typically supply to larger semiconductor companies face thin margins and different IP requirements to be supported across their customer base. On top of that, no one wants an IP that has not been proven in the field. But if you are looking to be an IP supplier for a low-power SoC that will be manufactured in leading edge p... » read more
