What’s Ahead For System-Level Design


By Ann Steffora Mutschler Architecting an SoC today is incredibly difficult. When you add in the number of available transistors, the manufacturing effects of smaller nodes, IP and software that must be integrated, among other things, the challenges just keep mounting. Depending on what market segment the SoC will be designed into has a huge impact, as well. “It is impossible to ove... » read more

Taking Stock Of Models


By Ann Steffora Mutschler The world of modeling in SoC design is multi-dimensional to say the least. One dimension contains the model creators and providers, while the other is comprised of the types of models that exist in the marketplace. “What we’re seeing today is that we have basically models coming from either IP providers—the people that are actually producing those cores ... » read more

Executive Outlook


By Ed Sperling The view from the top of companies is a like a high-level of abstraction for viewing the industry. While engineers get caught up in individual projects, or pieces of projects, CEOs and CTOs tend to see things from a much broader perspective. So what do they see as the big issues and developments over the next 12 to 24 months? System-Level Design asked industry leaders that q... » read more

Engineering Change Orders Revisited


By Ed Sperling The perennial nightmare of the marketing head reporting that a customer will buy a design—but only if it fits into a specific power envelope or has better performance or I/O—is all too familiar to engineering teams. In theory, using more third-party IP should help alleviate this problem because the IP can be changed out relatively easily. The reality, though, is that it�... » read more

The Essential Tool Kit


By Ann Steffora Mutschler Is there an essential chip design tool kit today that has only the ‘must haves?’ Sure, this sounds like a straightforward question, but the answer really depends on what process node the design will be manufacturing on. According to Jon McDonald, technical marketing engineer for the design and creation business at Mentor Graphics, there’s actually nothi... » read more

The Growing Confidence Gap In Verification


By Ed Sperling It’s no surprise that verification is getting more difficult at each new process node. What’s less obvious is just how deep into organizations the job of verifying SoCs and ASICs now extends. Functional verification used to be a well-defined job at the back end of the design flow. It has evolved into a multi-dimensional, multi-group challenge, beginning at the earliest st... » read more

Thanks For The Memories


By Ed Sperling The amount of real estate in a design now devoted to memories—SRAM on chip, DRAM off chip, and a few other more exotic options showing up occasionally—is a testament to the amount of data that needs to be utilized quickly in both mobile and fixed devices. Memory is almost singlehandedly responsible for the routing congestion now plaguing complex SoCs. It is one of the mai... » read more

Where Does It Hurt?


By Ed Sperling The IC design industry is feeling a new kind of pain—this one driven by uncertainty over architectural shifts, new ecosystem interactions and new ways to account for costs. As mainstream ICs move from 50/45/40nm to around 32/28/22nm, there are only two choices for design teams—continue shrinking features or stack dies. In many cases, the ultimate solution may be a combina... » read more

Inflection Points Ahead


By Ed Sperling Engineering challenges have existed at every process node in semiconductor designs, but at 20nm and beyond, engineers and executives on all sides of the industry are talking about inflection points. An inflection point is literally the place where a curve on a graph turns down or up, but in the semiconductor industry it’s usually associated with the point at which a progres... » read more

Best Practices In Verification


By Ann Steffora Mutschler The advent of advanced verification methodologies such as the UVM and its predecessors VMM and OVM has changed the verification landscape in many ways. Design and verification teams used to worry about simulator performance (i.e., how fast the simulator runs a particular test case), but the introduction of constrained-random stimulus and functional coverage and associ... » read more
