It is unfortunate that design and verification methodologies have often been out of sync with each other, and increasingly so over the past 20 years. The design methodology change that caused one particular divergence was the introduction of design Intellectual Property (IP). IP meant that systems were no longer designed and built in a pseudo top-down manner, but contemplated at a higher level and constructed in a bottom up, ‘lego-like’ manner by choosing appropriate blocks that could implement the necessary functions.

Methodology Convergence
Thursday, August 8th, 2019Multi-Dimensional Verification
Tuesday, May 28th, 2019It seems like ancient history now, but in the not so distant past, verification was performed by one tool – simulation; at one point in the flow – completion of RTL; using one language and methodology – SystemVerilog and UVM. That changed when designs continued to get larger and simulators stopped getting fast enough. Additional help became necessary in the form of emulators and formal verification, but that coincided with an increasingly difficult task of creating a stable testbench. It was no longer possible to migrate a design from a simulator to an emulator without doing a considerable amount of work on the testbench. (more…)
Improve or Enable
Thursday, April 18th, 2019New tools, languages, or methodologies can be an improvement over existing ones, or they can be enablers for something different. The recently approved Accellera Portable Stimulus Standard (PSS) can be either or both. (more…)
System Functionality Includes Software
Monday, April 23rd, 2018Listening to users is never a bad thing. Users are the people who set Breker along its current direction and during the process of standardizing Portable Stimulus (PS), the ability to talk to an expanded group of users allowed Breker to see a larger portion of the total available market. We learned a lot. (more…)
Time To Be Heard
Monday, October 2nd, 2017Accellera 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.
Portable Stimulus Takes Center Stage At DVCon 2017
Thursday, February 23rd, 2017When 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.
