I have always been wanting to contribute to the growing verification engineering community in India, which Mentor’s CEO Wally Rhines calls “the largest verification market in the world”. So when I first accompanied the affable Dennis Brophy to the IEEE India office back in April of 2014 to discuss the possibility of having a DVCon in India, I knew I was at the right place at the right time and it was opportunity to contribute to this community.

I has been two years since that meeting, I don’t have to write about how big a success the first ever DVCon India in 2014 was. I’m glad I played a small part by being on the Technical Program Committee on the DV track, reviewing various abstracts. It is a responsibility which I thoroughly enjoyed. This year in addition to being on the TPC, I am contributing as the Chair for Tutorials and Posters. I am eagerly looking forward to the second edition of the Verification Extravaganza which is on 10th and 11th Sept 2015 and the amazing agenda we have planned for attendees.

Day 1 of the conference is dedicated to keynotes, panel discussions and tutorials while day 2 is dedicated fully to Papers with a DV track and a panel in addition to papers in a ESL track. Participants are free to attend any track and can move between tracks. This year we had many sponsored tutorials submissions hence, there will be three parallel tutorial tracks, one on the DV side and two on the ESL track.

Below please find a list of those that Mentor Graphics will be presenting at:

  • Keynote from Harry Foster discussing the growing complexity across the entire design ecosystem
    Thursday, September 10, 2015
    9:45am – 10:30am
    Grand Ball Room, The Leela Palace

  • Creating SystemVerilog UVM Testbenches for Simulation and Emulation Platform Portability to Boost Block-to-System Verification Productivity
    Thursday, September 10, 2015
    1:30pm – 3:00pm
    DV Track, Diya, The Leela Palace

The papers on day 2 are primarily split into 3 parallel tracks, one on DV track and 2 parallel tracks on ESL. Within the DV track, one area is dedicated to UVM/SV. The other categories within the DV track will cover Portable Stimulus & Graph Based Stimulus, AMS, SoC & Stimulus Generation, Emulation, Acceleration and Prototyping & a generic selected category. The surprise among the categories is Portable Stimulus, which was a tutorial in last year however has continued to be of high interest and sessions will build on last year’s initial tutorial.

Overall there is an exciting mix of keynotes, tutorials, panels, papers and posters, which will make two exceptional days of learning, networking and fun. I look forward to seeing at DVCon India, 2015 and if you see me at the show, please come say hello and let me know what you think of the conference.

StPatricksDay

With a name like “Fitzpatrick,” you knew I’d be celebrating today, right?

Well, there’s no better way to celebrate this fine day than to announce that our latest edition of Verification Horizons is available online! Now that Spring is almost here, there’s a bit less snow on the ground than there was when I wrote my introduction, but everything is still covered. I’m considering spray-painting it all green in honor of the occasion, so at least it looks like I have a lawn again.

In this issue of Verification Horizons, I’d particularly like to draw your attention to “Successive Refinement: A Methodology for Incremental Specification of Power Intent,” by my friend and colleague Erich Marschner and several of our friends at ARM® Ltd. In this article, you’ll find out how the Unified Power Format (UPF) specification can be used to specify and verify your power architecture abstractly, and then add implementation information later in the process. This methodology is still relatively new in the industry, so if you’re thinking about making your next design PowerAware, you’ll want to read this article to be up on the very latest approach.

In addition to that, we’ve also got Harry Foster discussing some of the results from his latest industry study in “Does Design Size Influence First Silicon Success?” Harry is also blogging about his survey results on Verification Horizons here and here (with more to come).

Our friends at L&T Technology Services Ltd. share some of their experience in doing PowerAware design in “PowerAware RTL Verification of USB 3.0 IPs,” in which you’ll see how UPF can let you explore two different power management architectures for the same RTL.

Next, History class is in session, with Dr. Lauro Rizzatti, long-time EDA guru, giving us part 1 of a 3-part lesson in “Hardware Emulation: Three Decades of Evolution.”

Our friends at Oracle® are up next with “Evolving the Use of Formal Model Checking in SoC Design Verification,” in which they share a case study of their use of formal methods as the central piece in verifying an SoC design they recently completed with first-pass silicon success. By the way, I’d also like to take this opportunity to congratulate the author of this article, Ram Narayan, for his Best Paper award at DVCon(US) 2015. Well done, Ram!

We round out the issue with our famous “Partners’ Corner” section, which includes two articles. In “Small, Maintainable Tests,” our friends at Sondrel IC Design Services show you a few tricks on how to make use of UVM virtual sequences to raise the level of abstraction of your tests. In “Functional Coverage Development Tips: Do’s and Don’ts,” our friends at eInfochips give you a great overview of functional coverage, especially the covergroup and related features in SystemVerilog.

I’d also like to take a moment to thank all of you who came by our Verification Academy booth at DVCon to say hi. I found it incredibly humbling and gratifying to hear from so many of you who have learned new verification skills from the Verification Academy. That’s a big part of why we do what we do, and I appreciate you letting us know about it.

Now, it’s time to celebrate St. Patrick’s Day for real!

23 February, 2015

It’s my favorite time of year again—DVCon!  And I believe that the DVCon 2015 technical program committee has put together one of the technically best DVCon’s in years. In this blog I plan on highlighting a few DVCon events that you might want to put on your calendar.

2015-DVCon

First, at this year’s conference the Verification Academy has a dedicated booth (#301), and I hope you stop by to say hello to myself, my friend Tom Fitzpatrick, and an amazing lineup of other Verification Academy subject matter experts.

Next, on Wednesday morning March 4 I have the honor of participating on a verification panel, titled: “Art of Science.” Here, my fellow panelist and I will debate the issue that verification today is considered by some to be more of an art than a science—and one which is perceived as difficult to master. To learn my position on this topic, you’ll have to stop by!

Also on Wednesday at the Mentor sponsored lunch, my colleague Steve Bailey and I have put together both an informative and entertaining talk we’ve title: “From Tightly Coupled (Loosely Bolted) to Verification Convergence.” Here, we discuss the state of verification past, present and future while examining the results from our recently industry world-wide study, which I started blogging about a few weeks ago (click here for more details). Our talk will examine how advanced techniques are taking hold in mainstream design and provide insights on the recent convergence of verification solutions to meet today’s growing challenges.

Finally, there are two tutorials I’d like to encourage you to attend while at DVCon this year:

  1. Advanced, High-Throughput Debug from Architectural Modeling Through Post-Silicon SoC Validation (click here for more details)
  2. Dead or Alive: Using Automated Formal Techniques to Characterize Dead Code, Reveal Paths to Hit Uncovered States, and Reach Coverage Closure Faster (click here for more details)

I look forward to meeting you at DVCon 2015!

Accellera Approves Creation of Portable Stimulus Working Group

At DVCon 2014, Mentor Graphics proposed Accellera launch an exploratory exercise, called a Proposed Working Group (PWG), to determine if there was sufficient interest and need to create a standard in this area.  To help motivate the consideration of this activity, we indicated we would offer our graph-based test specification embodied in our inFact verification tool.

Rapid adoption of our technology has been the trend, especially when used in conjunction within a SystemVerilog UVM testbench environment.  One of the major benefits of UVM has been the portable nature of the testbench to facilitate design verification within and across companies.  The exclusive nature of our graph-based test specification language limits its easy use within the industry leading users to suggest we look to standardize it in keeping with the fundamental UVM principle of testbench portability.

After about a year of discussion in Accellera, the group announced it had concluded there should be an official standards project in this area.  Industry participants have likewise offered quotes of support for the formation of the Accellera Portable Stimulus Working Group.

The challenges to efficient and effective verification continue to grow.  If we stop where we are today in verification algorithm advances and standards the trend to require more people, time or compute resources will continue grow unabated at exponential rates.

For Mentor Graphics part, the verification team here has gone to market with innovative technology that has shown remarkable ability to improve verification productivity and efficiency.  The specification we offer to Accellera to seed this project is the same embodied in technology we used when we partnered with TSMC to validate advanced functional verification technology we announced in 2011.  From that announcement, we shared that tests conducted by AppliedMicro in designs destined for TSMC shortened “time-to-coverage by over 100x.”

One need not wonder if it is possible to shrink a month’s worth of verification tests into less than an 8 hour work day.  It is.  To find out how our specific use of this technology works and what motivates us to support standardization of Portable Stimulus in Accellera, I invite you to visit the Verification Academy where a session on Intelligent Testbench Automation shows what can be done.

And for those who would like to help in the development of the standard and may have technology to further underpin it, you should consider attending the first organizational meeting of the Portable Stimulus Working Group at DVCon 2015 March 5th from 6pm-9pm.  Contact Accellera for member-only meeting details or catch me at DVCon 2015 and I can share more information with you.

“Who Knew?” about verification IP (VIP), was the theme of a recent DeepChip post by John Cooley on December 18.  More specifically the article states, “Who knew VIP was big and that Wally had a good piece of it?”  We knew.

We knew that ASIC and FPGA design engineers can choose to buy design IP from several alternative sources or build their own, but that does not help with the problem of verification.  We knew that you don’t really want to rely on the same source that designed your IP, to test it.  We knew that you don’t want to write and maintain bus functional models (BFMs) or more complete VIP for standard protocols.  Not that you couldn’t, but why would you if you don’t have to?

We also knew that verification teams want easy-to-use VIP that is built on a standard foundation of SystemVerilog, compliant with a protocol’s specification, and is easily configurable to your implementation.  That way it integrates into your verification environment just as easily as if you had built it yourself.

Leading design IP providers such as ARM®, PLDA, and Northwest Logic knew that Mentor Graphics’ VIP is built on standards, is protocol compliant, and is easy to use.  In fact you can read more about what Jim Wallace, systems and software group director at ARM; Stephane Hauradou, CTO of PLDA; and Brian Daellenbach, president of Northwest Logic; have to say about Mentor Graphics’ recently introduced EZ-VIP technology for PCIe 4.0 (at this website http://www.mentor.com/company/news/mentor-verification-ip-pcie-4 ), and why they know that their customers can rely on it as well.

Verification engineers knew, too.  You can read comments from many of them (at Cooley’s website http://www.deepchip.com/items/dac14-06.html ), about their opinions on VIP.  In addition, Mercury Systems also knew.  “Mentor Graphics PCIe VIP is fully compliant with the PCIe protocol specification and with UVM coding guidelines. We found that we could drop it into our existing environment and get it up and running very quickly”, said Nick Solimini, Consulting DV Engineer at Mercury Systems. “Mentor’s support for their VIP is excellent. All our technical questions were answered promptly so we were able to be productive throughout the project”.

So, now you know,  Mentor Graphics’ Questa VIP is built on standard SV UVM, is specification compliant, is easy to get up and running and is an integral part of many successful verification environments today.  If you’d like to learn more about Questa VIP and Mentor Graphics’ EZ-VIP technology, send me an email, and I’ll let you in on what (thanks to Cooley and our customers) is no longer the best kept secret in verification.  Who knew?

9 October, 2014

DVCon India, held in September 2014 in Bangalore, built on the Indian SystemC User Group meeting events and added a Design & Verification track to its popular system-level design (ESL) track that has been popular for many years.  The main stage played host to the keynote presentations, opening ceremonies and best paper and poster awards.

Several DVCon India keynote presentations, which I will go into more depth later touched on emerging use of virtual platforms in system design and the growing impact India has on design verification.  In particular, Mentor’s CEO, Wally Rhines contrasted Wilson Research survey data on design verification from India and the rest of the world.  A strong adoption of SystemVerilog and its popular methodology, the Universal Verification Methodology (UVM) was clear from the survey results Wally shared.

But even beyond SystemVerilog and UVM, the discuss of what could come next anchored the first day of DVCon India discussion on Accellera’s exploration of “portable stimulus.”  Accellera has a group exploring if the industry is ready to start a standards project on this concept.  And the first day when DVCon India attendees were offered an opportunity to learn about this, the multi-company (Mentor Graphics, Breker & CVC) tutorial on the topic was standing room only.

DVCon Europe – The Stage is Set!

A tutorial slot at DVCon Europe will be devoted to the same topic that was popular at DVCon India.  For DVCon Europe attendees, you will find Tutorial T9, “Creating Portable Tests with a Graph-Based Test Specification” will cover this topic.  Technical representatives from Mentor Graphics and Breker will cover aspects of portable stimulus and offer examples of how it can work.  And early application of the technology will be covered by a representative from IBM.  To cover the topic appropriately, we have modified the presenters listed in the official printed program and full details are available online.  The presenters will be, in this order:

  • Holger Horbach, IBM, Germany
  • Frederic Krampac, Breker, France
  • Staffan Berg, Mentor Graphics, Sweden

Please join us for this tutorial and ensuing conversation and discussion.  Verification productivity is a pressing issue and our ability to better control and create stimulus is a step in the direction to address the verification challenges we all face.

One last note, the concept of “portable stimulus” is language agnostic so no matter which language you use for design and verification, the intention is this technology will be able to help.   The tutorial will help you understand how using a graph-based approach enables the highest degree of verification re-use, from IP block to sub-system to full-system level verification. You will see how it supports verification in SystemVerilog, Verilog, VHDL, C, C/C++, assembly, and even other non-traditional base languages. And it also can be extended from simulation to emulation to FPGA prototyping, and even silicon validation.

I look forward to seeing you at DVCon Europe in Munich!  And if you have not yet registered, please do so to secure your seat.

The ever popular Accellera Design & Verification Conference held annually in Silicon Valley is going global.  Accellera System Initiative has expanded many of its SystemC user group events to be more inclusive of other Accellera and IEEE standards.  In doing so, the local organizers of these events have moved to adopt the popular DVCon USA style to organize their events to include this large complement of standards.  If you want to attend, participate or contribute to the events, follow the links as shared below.

Mentor Graphics is excited to participate and sponsor these user-led events with a keynote address, technical paper presentations and educational tutorials.  We look forward to see you in September for DVCon India in Bangalore and in October for DVCon Europe in Munich.

DVCon Europe (14-15 October 2014 | Munich, Germany) will target the application of standardized languages, tools, and methodologies for the design and verification of electronic systems and integrated circuits. The two day event will feature tutorials on the first day and technical paper presentations and poster sessions on the second day.  The DVCon Europe program list the details of the conference.  It is collocated with the annual Forum on Design Languages (FDL), which runs from 14-16 October 2014 in case you want to extend your stay for an extra third day.

At DVCon Europe Mentor Graphics is collaborating with our industry peers and users on a tutorial titled Enabling Energy-Aware System Level Design with UPF-Based System Level Power Models. As power has become one of the major concerns in design equaling those of feature, function and performance, more advances are needed to address system power challenges.  The tutorial will explore the use of IEEE Std. 1801™ (UPF) and how design and verification flows can best use it.

Mentor Graphics will also sponsor a tutorial titled Creating Portable Tests with a Graph-Based Test Specification.  It will cover an overview of a graph-based test description language that raises the level of verification abstraction to address system level challenges. This technology is being used by many successful verification teams around the world today and it is the technology we have committed to help build a new standard upon in Accellera.

DVCon India (25-26 September 2014 | Bangalore, India) is the first year of the transition of the popular Indian SystemC User Group (ISCUG) meeting into an event that expands to cover topics that bring together all the stakeholder involved in design and verification of IP, SoC, ASIC, FPGA and system level solutions.   The event is over two days with common sessions in the morning for keynote addresses.  The attendees will then break into an ESL track and Design & Verification track for focused sessions.

Mentor Graphics will sponsor a tutorial session as well as host the keynote presentation by Mentor Graphics CEO, Dr. Walden C. Rhines.  Dr. Rhines will review recent Wilson Research Group study results on the ongoing convergence of SoC design practices towards a common methodology, independent of specify tools being use. In this keynote, Dr. Rhines identifies the common attributes of SoC methodology that are emerging, and will highlight specific capability enablers for the further optimization of SoC design verification.

Registration for both events is now open and I hope you have time in your calendar to make it there.  Both events will have an exhibition area where you can also catch up on recent updates to our products and discuss what you think should be added next.  The Mentor Graphics team looks forward to meeting you there!

DVCon 2014 Conference Proceedings Published

2014DVCon_logoWith record attendance announced for DVCon 2014, one might wonder if there is really a need to put some of the “Accellera Day” tutorial videos online.  With more than 1,000 professionals attending in some capacity, it would be easy to conclude that everyone that needs to know about UVM and the developments on the updated version to it, probably know.  Looking at just the LinkedIn design and verification forums one will realize there are 10’s of thousands who would have benefited if they had attended DVCon.  Thus, sharing this information more broadly is in order.

UVM Tutorial Video

UVM – What’s Now and What’s Next” is the tittle of the DVCon 2014 tutorial on UVM.  It covered use cases and pragmatic topics of the current UVM 1.1 standard as well as advanced topics for the next update, UVM 1.2.  The presenters covered sequence creation, register layer use, TLM-based communication, test execution, run-time phases and messaging enhancements.

The tutorial was split into five separate sections delivered by five speakers as follows:

  • Working Group Update: Adam Sherer, Accellera (7 min.)
  • Overview and Library Concepts: John Aynsley, Doulos (36 min.)
  • Stimulus Generation: Shawn Honess, Synopsys (21 min.)
  • UVM Register Layer: Tom Fitzpatrick, Mentor Graphics (36 min.)
  • UVM 1.2 Introduction: Uwe Simm, Cadence Design Systems (25 min.)

You can find out more information about the online tutorial videos hereRegistration is required, but there is no charge for access.  Once you have registered, you will get links to each of the five sections.  You can stream them or download them for offline access as you wish.  They are suitable for viewing on your computer or mobile devices.

DVCon 2014 Proceedings

DVCon 2014 was a full conference; it was more than just the the Accellera Day UVM Tutorial.  And in keeping with DVCon tradition, the conference proceedings are made available to all several months after the conference without charge.  If you visit the DVCon history area, you will find the 2014 proceedings have been published.  What I like about the DVCon proceedings it not only are the papers published, but the slides that were presented at the conference will often accompany the paper.

As an example, if you were interested in the DVCon 2014 Best Oral Presentation paper and presentation (Kelly D. Larson from NVIDIA on , “Determining Test Quality through Dynamic Runtime Monitoring of SystemVerilog Assertions” by the way), you will now find both the paper and presentation available online here.

For all those who did not make it to DVCon 2014, or who were there and could not see everything, the proceedings are now online and the first of the Accellera Day tutorials videos is published. Accellera is busy readying its other tutorial videos.  I’ll share information on their availability as they appear in the weeks and months ahead.

DVCon is always one of my favorite events in our industry, and I am proud to let you know that the latest issue of Verification Horizons is available “hot off the presses” at the Verification Academy to mark the occasion. For those of you attending the conference, please consider this issue as an addendum to the great technical program being offered (especially paper 8.1, “Of Camels and Committees: Standards Should Enable Innovation, Not Strangle It” by Dave Rich and yours truly). For those of you not able to join us at DVCon this year, consider this your consolation prize.

Although fewer in number, I’m sure you’ll find the articles in Verification Horizons as informational and useful as any you’ll see at DVCon. In particular, I’d like to make sure you check out these articles by our partners:

  • “Don’t Forget the Little Things That Can Make Verification Easier” by our friend Stu Sutherland of Sutherland HDL
  • “Taming Power-Aware Bugs with Questa Ultra” by SmartPlay Technologies
  • “Using Mentor Questa for pre-silicon validation of IEEE 1149.1-2013 based Silicon Instruments” by Intellitech
  • “Dealing With UVM and OVM Sequences” by eInfochips

If you’re at DVCon, please make sure to stop by the Mentor Graphics booth (#501) to say hi. Please join us on Wednesday for our luncheon presentation at noon, right after Session 8, in which I’ll present my paper mentioned above (that’s right. I’m not above shameless self-promotion). And we’ll wrap up the week with two Mentor-sponsored tutorials on Thursday:

Both of these tutorials feature a mix of Mentor presenters and customers to offer some practical examples that will give you some new ideas for improving your verification process. I hope to see you at DVCon.
