A Formal Transformation


A very important change is underway in functional verification. In the past, this was an esoteric technology and one that was difficult to deploy. It was relegated to tough problems late in the verification cycle, and it was difficult to justify the ROI unless the technology actually did find some problems. But all of that has changed. Formal verification companies started to use the technology... » read more

Coherency, Cache And Configurability


Coherency is gaining traction across a wide spectrum of applications as systems vendors begin leveraging heterogeneous computing to improve performance, minimize power, and simplify software development. Coherency is not a new concept, but making it easier to apply has always been a challenge. This is why it has largely been relegated to CPUs with identical processor cores. But the approach ... » read more

Are Simulation’s Days Numbered?


In the latest EDAC report, the value of IP surpassed the value of CAE tools for the first time. Verification tools are an important part of establishing confidence in IP blocks and simulation has been the mainstay of that IP verification strategy. But simulation is under increasing pressure, particularly for full-chip and SoC verification, because it has failed to scale. While it still remains ... » read more

How Many Cores? (Part 2)


New chip architectures and new packaging options—including fan-outs and 2.5D—are changing basic design considerations for how many cores are needed, what they are used for, and how to solve some increasingly troublesome bottlenecks. As reported in part one, just adding more cores doesn't necessarily improve performance, and adding the wrong size or kinds of cores wastes power. That has s... » read more

Preparing For The IoT Data Tsunami


Engineering teams are facing a flood of data that will be generated by the [getkc id="76" comment="Internet of Things"], both from the chip design side and from the infrastructure required to handle that data. There are several factors that make this problem particularly difficult to deal with. First, there is no single data type, which means data has to be translated somehow into a usable f... » read more

Racing To Design Chips Faster


A shift is underway to develop chips for more narrowly defined market segments, and in much smaller production runs. Rather than focusing on shrinking features and reducing cost per transistor by the billions of units, the emphasis behind this shift is less about scale and much more about optimization for specific markets and delivering those solutions more quickly. As automotive, consumer e... » read more

IP Requirements Changing


Twenty years ago the electronics industry became interested in the notion of formalizing re-use through third-party IP. It has turned out to be harder than anyone imagined. In 1996, the Virtual Socket Interface Alliance ([getentity id="22845" comment="VSIA"]) was formed to standardize the development, distribution and licensing of IP. Soon afterward, companies with a couple of people in a ga... » read more

Masters Of Abstraction


Good system designers are a unique breed. While it's easy enough to distinguish the traits that define a good one from a weak one, it's much harder to determine who possesses those traits before they are put to the test, or whether or how they can be taught. However, there is definitely a particular perspective that good system designers hold in common. The key is the ability to work with ma... » read more

Getting Formal About Debug


While much of the design and verification flows have been automated, debug remains the problem child. It has defied automation and presents a management nightmare due to the variability of the process. In recent articles about debug, we examined how much time development teams spend in the debug process and some of the reasons why it is becoming a bigger problem. This includes issues such as ex... » read more

Fallout From Scaling


By Ed Sperling & Ann Steffora Mutschler Semiconductor scaling is becoming much more difficult and expensive at each new node, creating sharp divisions about what path to take next for which markets and applications. What used to be confined to one or two clear choices is now turning into a menu of items and possibilities, often with no clear guarantees for a successful outcome. Views ... » read more
