Taming The Multicore Beast


By Ed Sperling Multicore chips are here to stay. Now what? That question is echoing up and down the ranks of tools vendors, design engineers, software developers and even among people who measure the performance and efficiency of semiconductors. There is now a Multicore Expo and a Multicore Association that includes a who’s who of electronics. And there are lots of working groups developing... » read more

Thinking Digital To Design Analog, And Vice Versa


By Ed Sperling Until several years ago, analog was a world apart from digital. Analog engineers could comfortably avoid many of the issues of Moore’s Law, viewing it as a costly bad habit with an equally bad outcome. Most analog engineers gloated privately that they could still develop chips at 250nm, or at worst 130nm, while their digital counterparts were struggling to keep up with is... » read more

Exploring The Use Of Virtual Platforms At The Electronic System Level


By Cheryl Ajluni System design is hard. That should not come as a surprise to anyone these days. With design geometries shrinking and device complexity on the rise, this fact is not likely to change anytime soon. One concept for easing that burden for system-level designers is the virtual platform. Granted, the concept itself is nothing new, but today it is being employed in ever more creativ... » read more

Trends in System-Level Prototyping


By Clive Maxfield One problem with electronics is that certain terms can mean different things, depending on who one is talking to at the time. Even worse, some terms have a tendency to evolve over time. This means that when we are presented with a topic like "Trends in System-Level Prototyping," before leaping headfirst into the fray, it may be a good idea to first define exactly what we mean... » read more

Why bother with ESL?


I’m in southern California today at the EDA Tech Form. I’ve been thinking about a conversation I had recently with a colleague. He’s been doing system-level modeling for a few years and has been an advocate for transaction-level modeling and ESL in his company. He has had tremendous success in identifying and fixing system-architecture issues before implementation, as well as saving his ... » read more

Verifying Low-Power IP And Designs


By Ed Sperling Verification has always been the time-consuming part of designs. Even at 120nm and above, where power wasn’t much of an issue, verification accounted for an estimated 70 percent of the non-recurring engineering expense in a chip. Since then, the tools to automate design have become more effective, but the complexity of designs has grown by leaps and bounds beyond those tools.... » read more

ESL Languages: Which One Is Right For Your Needs?


The question about ESL language is the right one comes up over and over again.  As customers begin to understand the benefits of modeling and analysis at the system level, they must address this question as one of the first steps in getting started.   What language should be used for ESL—SystemC, SystemVerilog, UML or M? Technically, you can create an ESL/TLM platform in any language yo... » read more

The In’s And Out’s Of Parasitic Extraction


Low-Power Engineering sat down with two of the top experts—Robert Hoogenstryd, director of marketing for design analysis and signoff at Synopsys, and Carey Robertson, Calibre product marketing director at Mentor Graphics—to talk about what changes at 28nm and 22nm and why parasitic extraction is becoming so important.
