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

Everything Changes At 45nm


Design engineers are pretty good about sharing ideas with their colleagues. They’re extremely good about sharing the limelight with their peers. But they’re not particularly good about implementing new ideas and concepts and changing the way they work.   There are good reasons for this, of course. It takes a long time to become proficient at skills for designing new chips or creating a... » read more

A Leap Of Faith


Complexity isn’t always bad. The key is being able to deal with it intelligently and economically.   Systems engineers are in the middle of one of the most complex periods in chip development. In the past, they typically had to deal with one problem at a time. At 1 micron, the wall was lithography. At 90 nanometers, it was low-k dielectric insulation (and yes, copper interconnects and 30... » read more

Must-Have Tools For Engineers


It may be one of the best equipped system-development labs on Earth, but it's largely used to create designs that aren't used on this planet. [youtube vid=khCj-7ftAzw] » read more

The Downturn’s Impact On Startups


The strong get stronger in a downturn for reasons that aren’t readily apparent at the outset of the slump.   First of all, contracts that are in place at the outset typically don’t get canceled—at least not at first, and frequently not at all. In the system-level design world, those contracts can last as long as 18 to 24 months. Even if the number of derivative chips is scaled back, ... » read more

Another Brick In The Wall


The wall is in sight.   Moore’s Law has propelled the semiconductor industry at an amazing velocity since it was first introduced in 1965, and despite some minor changes from 18 months to two years, we have pretty much stayed on course. In the past, most people thought we would hit the wall at 1 micron, and they thought it would happen again at 32nm. The road map appears pretty solid dow... » 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

NoC Your SoCs Off


By Ed Sperling The network on a chip (NoC) approach is gaining ground as an essential part of a system on a chip (SoC), providing the same kind of time-to-market advantage that well-tested intellectual property blocks provide. This follows almost eight years of hype about NoCs potential with little to show for it. Times have changed and there appear to be two main drivers, one technological a... » read more

Beyond CMOS: Making Way For The Next-Generation Of Semiconductor Materials


By Cheryl Ajluni Before the advent of the cell phone, the idea of having access to a phone virtually anytime, anywhere and in a package smaller than a human hand seemed almost impossible. Today that innovation, and others like it, has become an everyday reality. In the process it has helped spawn a technologically-driven society that continually demands more for less and waits impatiently... » read more
