Industry Struggles with System Coverage

 
March 15th, 2018 by Adnan Hamid, CEO of Breker

DVCon is a great place to talk to design and verification engineers. As the Accellera Portable Stimulus Standard (PSS) gets closer to reality, we were able to share with them during the conference the progress made and the ways in which it may impact their task. Most of them are as excited about PSS as we are. While we have been working in this field for more than a decade and have received a lot of feedback, there are now many more people becoming aware of it and the potential that it has. This provides us with the opportunity to learn as well. Read the rest of Industry Struggles with System Coverage

UVM is Dead! Long live UVM+PS!

 
February 22nd, 2018 by Adnan Hamid, CEO of Breker

When the forebears of SystemVerilog and UVM were being created, the world was a different place. Verification was primarily directed testing and code coverage was good enough to signal completion. Development of directed tests was getting to be slow, cumbersome and difficult to maintain. Languages and tools were created that added the ability to randomize stimulus but that created two problems. First, you had no idea what a test had accomplished and second, you had no idea that the design had actually reacted in the right manner. Thus, two additional models became necessary: a combination of checkers and scoreboard and the coverage model. The big problem was, and remains, that the three models are independent models only unified by a thin layer of syntax. Read the rest of UVM is Dead! Long live UVM+PS!

Dual Focus Will Help Adoption

 
January 31st, 2018 by Adnan Hamid, CEO of Breker

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. Read the rest of Dual Focus Will Help Adoption

Solution = Standard + Tool

 
November 30th, 2017 by Adnan Hamid, CEO of Breker

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.  Read the rest of Solution = Standard + Tool

Time To Be Heard

 
October 2nd, 2017 by Adnan Hamid, CEO of Breker

Accellera has just extended the review period for the Portable Stimulus Standard. The committee is now seeking comments up until the end of October. Breker would like to join the committee and say how important it is for users to get involved with this standard. While we, as vendors, have some experience in this area, we are not doing this day in and day out. We need your guidance and feedback.

Breker applauds Mark Glasser, principal engineer for NVIDIA, for being a user who is spending the time and effort to understand the emerging Portable Stimulus Standard (PSS). The points he raised in his recent blog are shared by a number of other users in the industry. His passion comes from the fact that he sees the potential of the work that is being undertaken and the impact that it could have on the verification community and the entire system development flow.

Users are, by definition, those in the trenches experiencing the problems and trying to find solutions. Within that community, there are only a few that can see beyond the current design and can look towards the future. Of those, only a precious few can help to influence the direction of the future. If you are one of those, then we ask you to get involved. Sitting on a standards committee can be tough and often dirty work, but there is no better way to guide the future direction of the industry.

We share Mark’s feelings that we should leverage the extensive expertise that exists in the language design community. It has taken many hundreds of man years of effort to get C++ to where it is today and we have seen, during our interactions with users, the power and flexibility that C++ provides to this problem.

Understanding Portable Stimulus Graphs

 
September 13th, 2017 by Adnan Hamid, CEO of Breker

When people talk about the Portable Stimulus Standard (“PSS”) they throw around the term “graph based” as if that somehow clarifies everything. They usually don’t bother to describe what it means, beyond it being some simple mathematical model. Some vendors even confuse it with the term “graphical”. To simplify this confusion, for this blog we will use the term “visual”. This blog will answer questions about how PSS relates to graphs and how those graphs relate to other similar graph-based models already used within the industry.

Portable Stimulus Gains Momentum

 
August 24th, 2017 by Adnan Hamid, CEO of Breker

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

 
June 9th, 2017 by Adnan Hamid, CEO of Breker

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. Read the rest of Rewriting Revolutionary History

Total Value Of A Standard

 
May 22nd, 2017 by Adnan Hamid, CEO of Breker

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. Read the rest of Total Value Of A Standard

Portable Stimulus – The First Verification Model

 
April 4th, 2017 by Adnan Hamid, CEO of Breker

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?
