System Bits: July 23


Bottom-up nanoribbons Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up — atom by atom. As seen under a microscope, the layers brought onions to mind, according to Rice chemist James Tour, until a colleague suggested flat graphene could never be like an onion. “So I said,... » read more

Experts At The Table: SoC Prototyping


By Ann Steffora Mutschler System-Level Design sat down to discuss SoC prototyping with Hillel Miller, pre-silicon verification/emulation manager at Freescale Semiconductor; Frank Schirrmeister, group director, product marketing, system development suite at Cadence; and Mick Posner, director of product marketing at Synopsys. What follows are excerpts of that conversation. SLD: When it comes... » read more

Trading Off Power And Performance


By Ann Steffora Mutschler There is no shortage of opinions when it comes to the topic of performance and power tradeoffs. From abstracting the task from engineers to process considerations, engineering teams have a number of tools and approaches at their disposal to make the optimal design choices for their application. Take the MCU application space for instance. Ken Dwyer, director of app... » read more

Software Debug Gets Tricky


By Ann Steffora Mutschler As designs continue to grow in size and complexity, that complexity has led to an increasing number of processing cores. Additional cores, in turn, allow for additional software to be run on those cores, and debugging the software becomes critical. Traditionally, emulation has played a significant role in verifying that software against RTL code, and continues to d... » read more

The Controversial Spec


By Ann Steffora Mutschler Design sophistication and complexity has made it increasingly difficult to fully specify the expected behavior of a block in an SoC, but this is necessary for design and verification teams. How do you write a “good” and “complete” specification of functionality? It turns out that the discussion of defining what a good and complete specification is and how t... » read more

To DVFS Or Not To DVFS


I’m in a great position to hear lots of interesting opinions about technology today and this week was no different. During a discussion with Atrenta CTO Bernard Murphy about power and performance tradeoffs, he mentioned that he is not hearing a lot of engineering teams using DVFS (dynamic voltage and frequency scaling) because it creates complications for clock synchronization and makes the d... » read more

System Bits: July 9


New quantum computing algorithm Researchers at the University of California, San Diego, have proposed a new algorithm for quantum computing that they believe will speed a particular type of problem…but swifter calculations would come at the cost of greater physical resources devoted to precise timekeeping. The algorithm would be used to conduct a task called an unstructured search. The go... » read more

The Ubiquitous GPU


By Ann Steffora Mutschler No matter the application area, GPUs are likely playing a role like never before—even to accelerate EDA software algorithms. It’s no wonder given the ability of GPUs to handle parallel processing much more effectively than CPUs. And when coexisting in a heterogeneous system, GPUs allow the design team to maximize efficiency and performance by allocating tasks... » read more

Watching And Waiting For DFP


By Ann Steffora Mutschler Although the semiconductor industry has been talking about the need to optimize SoC designs for power for many years, it is safe to say it’s still in the very early stages of the 'Design for Power' approach. That’s not to say that methodologies and tools are not in place. There are actually a number of options available, depending on the level of abstractio... » read more
