A Team Is Only As Strong As Its Captain


By Tom De Schutter Last week I was in Cambridge, UK. Although the weather wasn’t great, which seems to be pretty standard every time I visit, it actually didn’t rain a whole lot. That was a victory in itself. On one of the evenings I was eating with some colleagues at a restaurant overlooking Parker’s Piece, a 25-acre square of grass near the center of Cambridge. Frequent visitors of ... » read more

Formal Verification Comes Of Age


By Ann Steffora Mutschler Formal verification technology, also known as formal property checking, has been in existence since the early 1990s. Still, it’s only in the past five years that it has made big strides in the last five years in terms of the capacity of the technology to handle bigger pieces of a design, leveraging advancements in computing as well as improvements to the algor... » read more

Reducing Wait Time


By Tom De Schutter Last month we were all waiting for white smoke to emerge from the chimney on the roof of the Sistine Chapel at the Vatican. I am of course talking about the election of the new pope. I couldn’t help but see a parallel with how software developers are anxiously waiting for their software to run correctly and finally get past the series of seemingly never ending bugs (black ... » read more

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

Like Oil And Water


By Ann Steffora Mutschler For years, the promise and allure of a concurrent design methodology included talk of models, high-level synthesis, virtual prototyping and other system-level technologies all peacefully coexisting in a single design methodology. While it sounds like a good idea, the model-based design approach hasn’t mixed well with the virtual prototype approach. And at l... » read more

The Good And Bad Of Models


By Ann Steffora Mutschler Driven by fierce competition and the fact that socket decisions are made long before silicon is manufactured, semiconductor companies today ship models and virtual prototypes to their OEMs very early in hopes of locking in the socket. Admittedly, this has been happening for some time, but due to complexity and the need for flexibility of models and virtual platf... » read more

Peace Overture


One look at the headline and you may think I’m going to suggest that virtual prototyping can solve the myriad issues between hardware and software teams but rest assured, I’m not. I will tell you that I’ve heard some promising anecdotes lately, and that is a little bit encouraging. When you finish reading, please chime in with your comments! In the course of interviewing Achim Nohl, te... » read more

Virtual Prototyping Takes Off


By Ann Steffora Mutschler Skyrocketing software development costs, which for years have been “somebody else’s problem,” are now firmly part of the SoC development teams list of headaches. That has made virtual prototyping far more popular, particularly at 40nm and beyond, where engineers are looking at this approach as a way of managing complexity, doing architectural exploration and eve... » read more

The Multiple Faces Of Virtual Prototyping


Virtual prototyping conjures either confusion or relief, so it should come as no surprise that some chip designers are still confused about the different types of prototypes on the market. “Virtual prototyping is going through a change right now,” explained Gary Smith, founder and chief analyst for Gary Smith EDA. “Today, users are using cycle-based tools to prototype sections of their... » read more
