Keeping Models In Sync


By Ed Sperling Models and higher levels of abstraction have been hailed as the best choice for developing SoCs at advanced process nodes, but at 28nm and beyond even that approach is showing signs of stress. The number of models needed for a complex SoC has been growing at each new process node, which makes it much more difficult to keep them updated and in sync as the design progresses down t... » read more

Experts At The Table: The Power Problem


Low-Power Engineering sat down to discuss a broad swath of power issues with Vic Kulkarni, general manager and senior vice president of the RTL business unit, Apache Design Solutions; Pete Hardee, solutions marketing manager at Cadence; Bernard Murphy, chief technology officer at Atrenta, and Bhavna Agrawal, manager of circuit design automation at IBM. What follows are excerpts of that conversa... » read more

Pricey Processes For Low Power


By Pallab Chatterjee Recently Samsung gave an update on the status and availability of its advanced 32/28nm process technology for use in foundry. The process is targeted for shipping designs to customers at the end of this year, with a road map that continues through the 22/20nm nodes and down to 15nm. What was particularly interesting were several key innovations that have made this all p... » read more

It’s All About Power


In my last entry regarding IBM’s claim for new x86 technology for the datacenter, I mentioned I was trying to get an answer from IBM regarding details on the “silicon innovation” it used. That quest is ongoing, and I hope to find some actual technology, and not just marketing mumbo-jumbo at the heart of it. Keep checking back, I will give my report here. Just a few weeks after Big Blue... » read more

Grappling With Graphene


By Brian Fuller Silicon CMOS is a tough act to follow. The workhorse building block for the world’s electronics has been delivering for system designers for a half century. Despite hand-wringing over its apparent scalability limits, it shows only vague signs of slowing down. For nearly as many years, it seems, the next great material or alternative to silicon CMOS has popped into the indu... » read more

The Long And Painful Path To Power Optimization


By Ed Sperling Think about any mobile Internet device today. Batteries typically last all day, applications shut down with ease, and the number of things it can do has reached the point where many people typically carry one device on the road rather than multiple devices they used to lug around several years ago. Perhaps even more astounding is the price drop on these devices. A basic cell ... » read more

New x86 Technology For The Datacenter?


I wasn’t too surprised when IBM announced new servers early this month that they claim “break constraints of 30-year technology design,” since Big Blue is constantly releasing new products that they say are groundbreaking in one way or another. Reading deeper into the news, IBM is using new semiconductor technology at the heart of its new eX5 servers that it said took its engineering t... » read more

Remaking The Design Landscape


By Ed Sperling Every now and then a new trend comes along in the semiconductor design world, often because an old tool doesn’t work well anymore or because a new one is achieving critical mass. Lithography moved to immersion when the wavelength couldn’t be refracted far enough anymore. Designers at the advanced end of Moore’s Law began using tools like high-level synthesis and Transa... » read more

Journey To The Center Of The Ecosystem


From the outside it looks like business as usual, but the race for board seats on the GSA has become particularly competitive this year. GSA originally was created as an organization for fabless companies, but you wouldn’t know that looking at its membership roster. It has evolved into a who’s who of the entire semiconductor supply chain, including everyone from foundries like TSMC and... » read more

Greener Data Centers


By Ed Sperling For decades the race inside the data center was all about performance. If you upgraded from an IBM Series/370 mainframe to a Series/380 your applications ran faster. And if you upgraded your PC server from a Pentium II to a Pentium 4 you got significantly better performance. The race now is to reduce the number of servers altogether, to lower the cooling costs per server ra... » read more
