Finding And Avoiding Concurrency Bugs
By Luis Murillo - 25 Apr, 2019 - Comments: 0

Understanding the intended and unintended interactions between hardware and software components is changing as architectures become more heterogeneous and interconnect topologies get more complicated. This affects performance, power consumption and cost of the project. Lots of universities are researching this from a software perspective, while a small number are looking at the implications fro... » read more

Taming Concurrency
By Brian Bailey - 17 Jan, 2019 - Comments: 2

Concurrency adds complexity for which the industry lacks appropriate tools, and the problem has grown to the point where errors can creep into designs with no easy or consistent way to detect them. In the past, when chips were essentially a single pipeline, this wasn't a problem. In fact, the early pioneers of EDA created a suitable language to describe and contain the necessary concurrency ... » read more

The Perfect Risk
By Brian Bailey - 27 Sep, 2018 - Comments: 0

The development of semiconductors is an act of risk management. Very simply put, if you take on too much risk, it could lead to product failure or a missed market window, both of which can cost $M. For a company that only produces one or two products a year, that can spell total disaster. If you do not take on enough risk, you are probably not going to end up with a competitive product that ... » read more

Using More Verification Cores

Semiconductor Engineering sat down to talk about parallelization efforts within EDA with Andrea Casotto, chief scientist for Altair; Adam Sherer, product management group director in the System & Verification Group of Cadence; Harry Foster, chief scientist for Mentor, a Siemens Business; Vladislav Palfy, global manager for applications engineering at OneSpin; Vigyan Singhal, chief Oski for ... » read more

How To Handle Concurrency
By Brian Bailey - 30 Oct, 2017 - Comments: 3

The evolution of processing architectures has solved many problems within a chip, but for each problem solved another one was created. Concurrency is one of those issues, and it has been getting much more attention lately. While concurrency is hardly a new problem, the complexity of today’s systems is making it increasingly difficult to properly design, implement and verify the software an... » read more

The Limits Of Parallelism
By Ann Mutschler - 22 Nov, 2016 - Comments: 0

Parallelism used to be the domain of supercomputers working on weather simulations or plutonium decay. It is now part of the architecture of most SoCs. But just how efficient, effective and widespread has parallelism really become? There is no simple answer to that question. Even for a dual-core implementation of a processor on a chip, results can vary greatly by software application, operat... » read more
