3 Ways To Differentiate
By Ed Sperling - 13 Jan, 2013 - Comments: 0

Time-to-market pressures and complexity have put the squeeze on design teams. They have to bring incredibly complex SoCs to market on time, make sure they’re functionally correct and work within a tight power budget, and they have to come in on or under budget. Amazingly, they’re still able to accomplish this, thanks to some heroic efforts on the part of engineers and some incredible adv... » read more

The Fine Art Of Compromise
By Jon McDonald - 19 Dec, 2012 - Comments: 0

By Jon McDonald Ask 10 people a question and you might get 10 different answers. Ask 10 software engineers what they need in a hardware platform and you might get more than 10 different answers because each probably will have a list of needs for the platform to deliver. Getting them to agree on acceptable targets may not be as difficult as a budget compromise, but project failure is a more pe... » read more

The Complexity Of System Development And Verification
By Frank Schirrmeister - 23 Oct, 2012 - Comments: 1

By Frank Schirrmeister The electronics industry is undergoing a fast transition towards new paradigms for system development and verification as traditional development methods reach their breaking points. Developing a system development and verification environment can become a costly undertaking, and can involve many direct and sometimes even more hidden cost. To understand the cost aspects,... » read more

Blurring The Lines At The OS Level
By Ed Sperling - 13 Sep, 2012 - Comments: 0

By Ed Sperling Picking an operating system—or choosing not to use an operating system—is becoming as complex a decision as choosing which IP to use in an SoC. Even decisions that sound straightforward may have ramifications on the total system power budget or performance, requiring them to be an integral part of the overall architectural process. But the choice of operating systems, as ... » read more

Inflection Points Ahead
By Ed Sperling - 23 Aug, 2012 - Comments: 0

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

Interface Additions To The e Language For Effective Communication With SystemC TLM 2.0 Models
By Various Writers - 23 Aug, 2012 - Comments: 0

The last several years have seen strong adoption of transaction-level models using SystemC TLM 2.0. Those models are used for software validation and virtual prototyping. For functional verification, TLMs have a number of advantages—they are available earlier, they allow usersto divide their focus on verifying functionality and protocol/timing details, they enable higher level reuse, and they... » read more

Development of Complex Multicore Systems: Tracing Challenges and Concept (Part One)
By Various Writers - 23 Aug, 2012 - Comments: 0

This white paper is the first paper of a two-part Mentor Embedded multicore white paper series. In this paper, the challenges software developers face when developing, debugging, and validating software applications for a complex multicore system will be discussed. The paper also highlights some of the questions around hardware resource usage, tracing aids, tracing domains, and concepts for col... » read more

The Seven Layers Of Hardware-Software Debug
By Frank Schirrmeister - 22 Aug, 2012 - Comments: 0

By Frank Schirrmeister [caption id="attachment_9863" align="alignnone" width="639"] Seven Layers of Hardware/Software Debug[/caption] Of course I will be in trouble once this blog is posted. This post is about hardware/software debug,  and I tried to layer a set of different levels for the scope and applicability of debug. I counted seven layers, but I am sure that one may be able to arr... » read more
