The Making of a Standard

Thursday, June 21st, 2018

The industry waits with bated breath for the Accellera board to approve the Portable Stimulus 1.0 specification. It has been a long and arduous process over the past four years to get to this point, a process that most people never get to experience. This was my first standard, and to say it was an eye opener is somewhat of an understatement. In this blog, I am not going to dwell on the many bruises I suffered or the technical discussions that often seemed like personal attacks. Instead, I want to make the industry aware of some of the difficulties associated with bringing a new and somewhat revolutionary standard to market. (more…)

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…)

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.

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…)

Constrain Me, Please

Thursday, December 8th, 2016

In the movies, when a person acts irrationally they are usually declared to be mad and quickly placed in a straitjacket for the protection of themselves and those around them. If we continue those thoughts into the world of verification, SystemVerilog must be declared to be a mad language. (more…)

EDA Hates C++. Wait, What – Back Up!

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

The Genesis of Portable Stimulus

Tuesday, October 25th, 2016

When I first met Adnan Hamid, Breker’s CEO, his philosophical understanding of verification and its implications for electronics was as crystal clear then as it is now. He sees it as the enabler for greater innovation in chips and beyond, and takes it as his life’s mission. His passion was inspiring to me and I did not hesitate for a second when we decided to jointly start Breker. Throughout our journey, I have watched the market converge with what we are building at Breker, and have come to better appreciate my partner, the visionary man. (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.

User Victory in Portable Stimulus

Thursday, September 8th, 2016

As regular readers know, the Portable Stimulus Working Group (PSWG) of the Accellera System Initiative has been working for some time to develop a new way to define verification intent once and to be able to reuse that across all stages of the verification flow and to be able to reuse it across designs. This will dramatically increase verification efficiency and establish verification methodologies that are likely to be used for the next couple of decades. (more…)
