Dual Focus Will Help Adoption

Wednesday, January 31st, 2018

One of the great things associated with the development of a standard, such as the Portable Stimulus Standard (PSS), is that it brings together various stakeholders – often a broader selection of people than any single company did business with. When you initially develop a product you gear it toward a particular problem, one that you have some familiarity with. The resulting product attracts engineers who resonate with the product and they provide valuable feedback. This in turn helps to make the product more attractive to engineers with a similar need. If you are not careful, you can have a product that targets a narrow part of the market and that is all you learn to explore. It is the Innovators Dilemma, and can stop a company from developing a general purpose product. (more…)

Solution = Standard + Tool

Thursday, November 30th, 2017

Solutions are what users need and the existence of a standard gives them the assurance that models they create will be portable between tools. Put another way, the standard creates a level playing field on which vendors can create tools that provide solutions.  (more…)

Portable Stimulus Gains Momentum

Thursday, August 24th, 2017

Next month will see a significant milestone for Portable Stimulus. On September 15th the review period for the Early Adopter release of the Accellera Portable Stimulus Standard (PSS) will close and with it the opportunity to make your voice heard. This is an exciting time for Breker, the market leader in this space for the past decade, and signals a time when the industry can transition from a technology only available to a few aggressive adopters, to making it available to the mainstream.

Rewriting Revolutionary History

Friday, June 9th, 2017

The semiconductor design industry has always preferred evolution over revolution. There have been a few successful revolutions but most of the time revolution happens over time through evolutionary steps. (more…)

Total Value Of A Standard

Monday, May 22nd, 2017

The creation of the Portable Stimulus standard has raised a number of issues about the tradeoffs between using an industry standard language and a domain-specific language. Several blogs have tried to make the case for one or the other and often use scare tactics to make one look better than the other. That is not the objective of this blog. Instead, it’s meant to provide some information as to why the inclusion of the C++ variant is a good thing for the industry. (more…)

Portable Stimulus – The First Verification Model

Tuesday, April 4th, 2017

When people think about design languages, they may not realize that the language is almost irrelevant. The language supports the underlying semantic model and it is this model that is important. EDA has defined design models at the gate level, the register transfer level (RTL) and various forms of behavioral levels. When we talk about RTL, we think about Verilog and VHDL, but they are only the languages that support that model, or very minor variations of it. But what about verification? (more…)

Users Talk Back on Portable Stimulus

Friday, March 17th, 2017

At the recent DVCon, I had the pleasure to moderate a panel that enabled users to talk about their experiences working with the Accellera standard’s body during the creation of the Portable Stimulus standard. I would like to thank Accellera for enabling such a panel and to Nanette Collins for organizing the panel and making sure that I had the easiest role in the ensuing discussion. I am sure that full write-ups of the panel will emerge, but I wanted to make the voice of the users heard. (more…)

Portable Stimulus Takes Center Stage At DVCon 2017

Thursday, February 23rd, 2017

When DVCon opens next week, attendees will hear plenty of talk about Portable Stimulus, a methodology and technology that’s grabbing industry attention and gaining momentum with the design verification community. In fact, I predict it will be the buzz of the conference this year.

EDA Hates C++. Wait, What – Back Up!

Friday, November 4th, 2016

Why is Accellera supporting the use of an industry standard language in the development of the Portable Stimulus Standard? (more…)

The Next Wave in Verification

Thursday, September 29th, 2016

There is an important standard being worked on within Accellera and given its name, you might think that this is another incremental standard on a somewhat tired theme. It is called Portable Stimulus and yet it has almost nothing to do with stimulus and that stimulus, once generated by a tool not defined in the standard, is most certainly not portable. It is a fundamentally new approach to verification that could transform how chips and low-level software are verified. We will get back to the name in a moment, but the important thing is that users become informed about this new language and choose to have their voices heard in the standardization effort.
