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.

From those just beginning to study electronic systems design to the practicing engineer, this is the time of the year when those taking their first steps to learn VHDL, Verilog/SystemVerilog join the academic “back to school” crowd and those who are using design & verification languages in practice are honing skills at industry events around the world.

A new academic year has started and the Mentor Higher Education Program (HEP) is well set to help students at more than 1200 colleges and universities secure access to the same commercial tools and technology used by industry.  It is a real win-win when students learn using the same tools they will use after graduating.  Early exposure and use means better skilled and productive engineers for employers.

The functional verification team at Mentor Graphics knows that many students would prefer to have a local copy of ModelSim on their personal computer to do their course work and smaller projects as they learn VHDL or Verilog.  To help facilitate that we make the ModelSim PE Student Edition available for download without charge.  More than 10,000 students use ModelSim PE Student Edition around the world now in addition to our commercial grade tools they can access in their university labs.

For the practicing engineer, the Verification Academy offers an online community of more than 25,000 design and verification engineers that exchange ideas on a wide variety issues across the numerous standards and methodologies.  If you are not a member of the Verification Academy, I recommend you join.  You will also find the Verification Academy at DAC for one-on-one discussions and even more recently Verification Academy Live daylong seminars which came to Austin and which will be in Santa Clara – as of the writing of this blog.  There is still time to register for the Santa Clara event and I invite you to attend.

As design and verification is global, Accellera realized that DVCon should explore the needs of the global design and verification engineer population as well.  For 2014, DVCon Europe and DVCon India were born from an already successful running SystemC User Group events.  These user-led conferences will be held so engineers in these areas can more easily come together to share experiences and knowledge to ultimately become more productive.

Students and practicing engineers alike can benefit from fee-free access to some of the popular IEEE EDA standards.   While I don’t think reading them alone is the ultimate way to educate yourself, they make great companions to daily design and verification activities.  Accellera has worked with the IEEE to place several EDA standards in the IEEE Standards Association’s “Get™” program.  Almost 16,000 copies of the SystemC standard (1666) and just about the same number of SystemVerilog standards (1800) have been downloaded as of the end of August 2014.  Have you download your free copies yet?

The chart below shows the distribution of nearly 45,000 downloads which have occurred since 2010.  Stay tuned for breaking news on some updates to the EDA standards in the Get program.  When updated, they will replace the versions available now.  So if you want to have the current versions and the ones to come out shortly, you better download your copies now.  If the electronic version is not sufficient for you, the IEEE continues to sell printed versions.

From students to practicing engineers, the season of learning has started.  I encourage you to find your right venue or style of learning and connect with others to advance and improve your design and verification productivity.

As DVCon expands, we at Mentor Graphics have grown our sponsored sessions as well.  Would you expect less?

In DVCon’s recent past, it was a tradition for the North American SystemC User Group (NASCUG) to sponsor a day of activity before the official start of the conference.  When OSCI merged with Accellera, the day before the official conference start grew to become Accellera Day with a broader set of meetings and activities covering many of Accellera’s standards.  This has all grown into a more official part of the DVCon program.  On Monday at DVCon – or as many still call it – Accellera Day – the tradeshow now joins in opening.  I covered this in detail in an earlier blog, so I won’t repeat myself now.

The pre-conference education and meet-up to discuss the latest in standards development is joined by an end of conference tutorial series that has expanded to allow four parallel sessions from three.  Instead of the one tutorial we at Mentor Graphics would otherwise sponsor at DVCon, we will offer two in this expanded series. Given the impact verification has on design it would seem right that more time be devoted to topics that address this.  One half-day tutorial is just to short to give the subject its due respect.

The two Mentor Graphics sponsored tutorials at DVCon, to be run in series, will devote a day to explore the application of current verification technology by us and users like you.  If you are already attending DVCon, you are making your tutorial selections now.  And for those who might only be interested to attend the tutorials themselves, DVCon offers a tutorials-only package ($145/Tutorial).  Mentor’s two tutorials are:

The first tutorial references “smooth sailing,” not because this will be a “no-pirate zone,” although I can tell you that since International Talk Like a Pirate Day is in late September, one won’t have to worry about a morning of pirate talk! [Interesting Fun Fact: Mentor Graphics’ headquarters in Wilsonville, OR USA is a short 50 miles (~80 km) north of the creators of this parotic holiday.]  The smooth sailing comes from the ability to easily use multiple engines from simulation, formal, emulation, FPGA prototyping to address your block to system-level verification needs.

The second tutorial is all about formal.  Or, in a more colloquial way to say it, we will answer the question: Whatsup with formal?  No, I doubt we will find more slang terms for formal technology being used and created in the tutorial.  But the tutorial will certainly look at more focused applications of formal technology.  As a pioneer in focused formal applications (like clock domain crossing) the creation of these focused formal applications has greatly simplified use and expanded technology access to verification teams with RTL design checks, X-state verification, and more joining the list.  Maybe we should ask Whatsapp with formal! But wait!  That slang question is already taken – and Facebook affirmed ownership with a $19B purchase of it recently.  Oh well, I lament.  Join me at this tutorial and we can explore something suitable and not yet taken as a replacement.  I can’t think of a better way to close DVCon than to see if we can invent another $19B term (or app).

DVCon 2014 LogoOne of the nice things about DVCon is the update one can get from the developers of IEEE and Accellera standards.  And this year’s DVCon is no exception.  The four days of DVCon begin and end with tutorials that cover updates to popular standards like UVM, UPF, SystemC and more.  For our part, Mentor Graphics is participating in the development and delivery of these updates with our peers.

UVM LogoI have written in the past about the productivity challenges before us to address the verification crisis and the emergence of machine-to-machine communication and the Internet of Things driving power aware design and verification.  To advance the demands on improved verification and help to address the verification crisis, the next round in the Universal Verification Methodology (UVM) standard is being readied for industry adoption.  UVM 1.2, the emerging update will be covered in some detail in a Monday morning tutorial to help you learn “What’s Now and What’s Next.”  Mentor Graphics’ Tom Fitzpatrick and Accellera Working Group representative will present in this tutorial.

UVM 1.2 is an active development project of Accellera and has not yet been released so there is no official standard available for download and use yet.  I’ll share standardization details as they happen.

At the same time on Monday, those who are concerned with power aware design and verification can attend the tutorial on the Unified Low Power Format (UPF), or as it is officially called IEEE 1801™-2013.  The tutorial will cover the full spectrum of UPF capabilities and methodology from basic to advanced applications.  So if you are new to UPF and want to learn, this is a great tutorial to attend.  And if you are already an expert, the advanced application of UPF as highlighted by those companies who have adopted UPF make this valuable for you as well.  Mentor Graphics’ Erich Marschner and IEEE 1801 Working Group vice-chair will participate in this tutorial.

UPF is an official IEEE standard.  Have you downloaded your copy yet?  Accellera has worked with the IEEE to make no-charge access to the official standard for you.  You can find the UPF standard here.

In the afternoon, there will be a session on case studies in SystemC.  User and vendor presentations will explore use of this standard.  SystemC offers much in the verification space, not just in technology but learning on how to bridge the RTL world with transaction level modeling world.  Mentor Graphics’ John Stickley will review what we have learned and how you can apply it to your most pressing verification needs.

SystemC is an official IEEE standard.  Have you downloaded your copy yet?  Under the Accellera agreement with the IEEE, you can download SystemC standard here.

There is a lot more to DVCon than just the use of current standards and planning adoption of emerging standards.  I encourage you to check out the whole agenda and join me at DVCon 2014 March 3-6.

Mentor Graphics presentations during the conference include:

  • Tuesday Paper Sessions
    • Amit Srivastava – Stepping Into UPF 2.1 World: Easy Solution to Complex
      Power Estimation
    • Kenneth Bakalar – Interpreting UPF For A Mixed-Signal Design Under Test
    • Gordon Allan – Tried and Tested Speedups for Software-Driven SoC Simulatio
  • Tuesday Poster Sessions
    • Rich Edelman – Debugging Communicating Systems: The Blame Game – Blurring
      the Line Between Performance Analysis and Debug
    • Matthew Balance – Tackling Random Blind Spots with Strategy-Driven Stimulus Generation
    • Gaurav K. Verma – Supercharge Your Verification Using Rapid Expression Coverage as the Basis of a MC/DC-Compliant Coverage Methodology

    • Rich Edelman – UVM SchmooVM – I Want My C Tests!
    • Thom Ellis – Are  You Really Confident That You Are Getting the Very Best From Your Verification Resources?
    • Jitesh Bansal – Is Your Power Aware Design Really X-Aware
  • Wednesday Paper Sessions
    • Avidan Efody – Wiretap Your SoC: Why Scattering Verification IPs Throughout Your Design Is A Smart Thing To Do
    • Tom Fitzpatrick – Of Camels and Committees: Standards Should Enable Innovation, Not Strangle It

Mentor Graphics will host its traditional lunch at DVCon on Wednesday on the theme of Accelerating Verification.  And we have lively panel participants for the Tuesday and Wednesday panels.  And, as always, the Exhibit, CEO Keynote and Panels are open to all a no charge – you just have to REGISTER!

I look forward to seeing you there!

We are truly living in the age of SoC design, where 78 percent of all designs today contain one or more embedded processors.  In fact, 56 percent of all designs contain two or more embedded processors, which brings a whole new level of verification challenges—requiring unique solutions.

A great example of this is STMicroelectronics who recently shared their experience and solution in addressing verification challenges due to rising complexity. In 2012, STMicroelectronics began a pilot project to build what it called the Eagle Reference Design, or ERD. The goal was to see if it would be possible to stitch together three ARM products — a Cortex-A15, Cortex-7 and DMC 400 — into one highly flexible platform, one that customers might eventually be able to tweak based on nothing more than an XML description of the system.

Engineers at STMicroelectronics sought to understand and benchmark the Eagle Reference Design. To speed this benchmarking along, they wanted a verification environment that would link software-based simulation and hardware-based emulation in a common flow.

Their solution was unique, and their story worth reading. They first built a simulation testbench that relied heavily on verification IP (VIP). Next, the team connected this testbench to a Veloce emulation system via TestBench XPress (TBX) co-modeling software. Running verification required separating all blocks of design code into two domains — synthesizable code, including all RTL, for running on the emulator; and all other modules that run on the HDL portion of the environment on the simulator (which is connected to the emulator). Throughout the project, the team worked closely with Mentor Graphics to fine-tune the new co-emulation verification environment, which requires that all SoC components be mapped exactly the same way in simulation and emulation.

Because the reference design was not bound to any particular project, the main goal was not to arrive at the complete verification of the design but rather to do performance analysis and establish verification methodologies and techniques that would work in the future. In this they succeeded, agreeing that when they eventually try this sort of combined approach on a real project, they will be able to port the verification environment to the emulator more or less seamlessly.

This is a great success story worth reading on how STMicroelectronics combined Questa simulation, Mentor verification IP (VIP), and Veloce emulation to speed up their benchmarking verification process. Check out the full story here!

Language and Library Trends

This blog is a continuation of a series of blogs that present the highlights from the 2012 Wilson Research Group Functional Verification Study (for a background on the study, click here).

In my previous blog (Part 7 click here), I focused on some of the 2012 Wilson Research Group findings related to testbench characteristics and simulation strategies. In this blog, I present design and verification language trends, as identified by the Wilson Research Group study.

You might note that for some of the language and library data I present, the percentage sums to more than one hundred percent. The reason for this is that some participants’ projects use multiple languages.

RTL Design Languages

Let’s begin by examining the languages used for RTL design. Figure 1 shows the trends in terms of languages used for design, by comparing the 2007 Far West Research study (in gray), the 2010 Wilson Research Group study (in blue), the 2012 Wilson Research Group study (in green), as well as the projected design language adoption trends within the next twelve months (in purple) as identified by the study participants. Note that the design language adoption is declining for most of the languages with the exception of SystemVerilog whose adoption continues to increase.

Also, it’s important to note that this study focused on languages used for RTL design. We have conducted a few informal studies related to languages used for architectural modeling—and it’s not too big of a surprise that we see increased adoption of C/C++ and SystemC in that space. However, since those studies have (thus far) been informal and not as rigorously executed as the Wilson Research Group study, I have decided to withhold that data until a more formal blind study can be executed related to architectural modeling and virtual prototyping.

Figure 1. Trends in languages used for Non-FPGA design

Let’s now look at the languages used specifically for FPGA RTL design. Figure 2 shows the trends in terms of languages used for FPGA design, by comparing the 2012 Wilson Research Group study (in red) with the projected design language adoption trends within the next twelve months (in purple).

Figure 2. Languages used for Non-FPGA design

It’s not too big of a surprise that VHDL is the predominant language used for FPGA RTL design, although we are starting to see increased interest in SystemVerilog.

Verification Languages

Next, let’s look at the languages used to verify Non-FPGA designs (that is, languages used to create simulation testbenches). Figure 3 shows the trends in terms of languages used to create simulation testbenches by comparing the 2007 Far West Research study (in gray), the 2010 Wilson Research Group study (in blue), and the 2012 Wilson Research Group study (in green).

Figure 3. Trends in languages used in verification to create Non-FPGA simulation testbenches

The study revealed that verification language adoption is declining for most of the languages with the exception of SystemVerilog whose adoption is increasing. In fact, SystemVerilog adoption increased by 8.3 percent between 2010 and 2012.

Figure 4 provides a different analysis of the data by partitioning the projects by design size, and then calculating the adoption of SystemVerilog for creating testbenches by size. The design size partitions are represented as: less than 5M gates, 5M to 20M gates, and greater than 20M gates. Obviously, we find that the larger the design size, the greater the adoption of SystemVerilog for creating testbenches. Yet, probably the most interesting observation we can make from examining Figure 4 is related to smaller designs that are less than 5M gates. Here we see that 58.8 percent of the industry has adopted SystemVerilog for verification. In other words, it is safe to say that SystemVerilog for verification has become mainstream today and not just limited to early adopters or leading-edge design projects.

Figure 4. SystemVerilog (for verification) adoption by design size

Let’s now look at the languages used specifically for FPGA RTL design. Figure 5 shows the trends in terms of languages used for FPGA design, by comparing the 2012 Wilson Research Group study (in red) with the projected design language adoption trends within the next twelve months (in purple).

Figure 5. Trends in languages used in verification to create FPGA simulation testbenches

In my next blog (click here), I’ll continue the discussion on design and verification language trends as revealed by the 2012 Wilson Research Group Functional Verification Study.

Download the standard now – at no charge!

The IEEE has published the latest update to the SystemVerilog standard.  And courtesy of Accellera, the standard is available for download without charge directly from the IEEE.

1800-2012 1

The latest update to the SystemVerilog standard is now ready for download.  It joins other EDA standards, like SystemC in the IEEE Get™ program that grants public access to view and download current individual standards at no charge as a PDF.  (If you wish to have an older, superseded and withdrawn version of the standard or if you wish to have a printed copy or have it in a CD-ROM format, you can purchase older and alternate formats from IEEE for a fee.)

Over the years Accellera came to understand that many people continued to use the freely available version that seeded the initial IEEE 1800 SystemVerilog standard.  Since it is significantly out of date, Accellera collaborated with the IEEE Standards Association to ensure the latest version of the SystemVerilog standard would be freely available in electronic form to all whom wish to download it.  Accellera now hopes all those old 3.1a versions that everyone has and uses can now be placed in the archives.

The new version of standard should be used by the UVM (Universal Verification Methodology) community as the definitive specification of the SystemVerilog standard upon which UVM is built.   It goes very well with the UVM Cookbook and the Coverage Cookbook.

From Mentor’s perspective, it also makes a good companion to the Questa verification platform and complements our latest product update in which we announced support for the IEEE 1800-2012 SystemVerilog standard among other things.

If you have not done so already, download your copy now by clicking here.

OVM Bridges SystemVerilog and SystemC Languages

When UVM Connect was first released, the multilingual connection between IEEE Std. 1800™ (SystemVerilog) and IEEE Std. 1666™ (SystemC) standards bridged the two languages to allow design and verification engineers to access UVM from SystemC or SystemVerilog to exploit native languages advantages.  OVM users wondered if it was possible to support them as well since OVM is a derived from UVM.

It is possible and UVM Connect has been extended to allow OVM users to enjoy the same benefits.  An update to UVM Connect now allows it to be compiled to run with the OVM.  And since the extensions are based on IEEE standards, they can be used in your simulator of choice.

OVM Thrives

The thriving OVM community is of no surprise.  Last year, Harry Foster blogged about research on the use and adoption of verification methodologies.  The research was done after UVM was established as an Accellera standard, and showed OVM continued its leading position as shown in one of the charts from Harry’s blog (see below).  The chart even showed OVM was predicted to have a modest growth in adoption as well.

Mentor continues to bring many of the UVM additions back to the OVM user community in a way that does not disturb the upgrade path from OVM to UVM.  The major addition to UVM in the first round of Accellera standardization was the addition of a register and memory package.  This was back ported to OVM.  (The OVM register and memory kit can be found here, if you are interested.)  Now, UVM Connect has been extended to provide full OVM use.

Download

The UVM Connect 2.2 kit supports multilingual use of OVM and can be found at the Verification Academy and the Accellera UVM World contributions download site.

If you find issues or have other suggestions that we should consider, you can always share your input at the OVM Forum or UVM Forum.  In addition to interacting with other users, the Verification Academy is a good site for online resources like the UVM/OVM Cookbook, basic and advanced OVM/UVM training, and more.

Open-Source Proof-of-Concept Library Released

Accellera Systems Initiative has released for general industry use an open-source proof-of-concept library as a companion to the recently minted IEEE Std. 1666™-2011, SystemC Language Reference Manual standard

In November 2011, the IEEE Standards Association approved IEEE Std. 1666-2011.  The completed and published standard was made available to the community as a whole for free in an agreement between Accellera Systems Initiative and the IEEE Standards Association in February 2012.   As a reminder, you can download your personal copy of IEEE 1666 here for free.

IEEE 1666-2011In the nearly 6 months since this version of the standard has been available about 7,000 copies have been downloaded under the IEEE Get program.

The previous version was also made available for free download and was just as popular as this version of the standard is.

1666-2011_Page_001While the approved standard was being made ready for publication, Accellera Systems Initiative was also busy completing the open-source proof-of-concept library.  After taking comments and feedback from a public review process, version 2.3.0 of the library was completed and is now available.

IEEE 1666-2011 added a number of important new features, including support for transaction-level modeling (TLM) that has proven to be an important element to enable high-level design and is a key component upon which the Universal Verification Methodology (UVM) is built from.

For those who want to used the SystemC library directly, it is now available for wide industry access.

Download Resources

The downloads from the IEEE and Accellera Systems Initiative will require some license agreement approvals.  The links are not one-click access to the material below.

Where might our paths cross?

It is always challenge to fit all the needed visits in during the Design Automation Conference (DAC).  If you happen to like some of the same events I attend, then the chances are good our paths might cross in public.

Saturday and Sunday are busy with an Accellera Systems Initiative board meeting.  Split across two days, Accellera board members will meet to conduct traditional business and  do some strategic planning in which each board member outlines what they aspire the goals and objectives for the group should be in the coming year.  Intel has graciously granted space in their San Francisco offices, so I won’t be around the Moscone Center during the pre-conference setup phase.  (By the way, Thank you Intel!)
After we close the Accellera board meeting on Sunday, I plan to attend the pre-DAC events on Sunday that include the EDAC reception (registration required) at 6:00pm  (San Francisco Marriott, Salon 7) and Gary Smith’s “Sunday Night at DAC” at 7:00pm (San Francisco Marriott, Salon 6).

During the conference I will spend most of my time at the Mentor Graphics Verification Academy Booth  #1514 and on Wednesday split my time between there and the Accellera Systems Imitative meetings.  And just in case you may note that most of my evenings are not scheduled, they are with customer activities.

MentorGraphics-LogoWhen the show floor is open, you will find me most of the time at the Verification Academy Booth #1514.  I will join Mentor’s Harry Foster there were user and partner presentations will be done on UVM applications, updates on Harry’s research results, updates on important verification standards from Mentor’s perspective and more.  You are invited to join other verification experts for the Tuesday evening cocktail reception at the Verification Academy Booth.  (And the cocktail hour may be just the thing that tis needed before the annual DAC Birds-Of-A-Feather meetings begin to help the conversations start.)

This luncheon is open to all DAC attendees. Seating is limited! You must pre-register for this event.

Coverage metrics are critical to measuring and guiding design verification. As designs have grown, increasingly advanced verification technologies, methods and additional metrics have been designed to form a fuller coverage model. There is currently no single metric that consistently and globally tells engineers the exact status of verification. But one step in the right direction is to bring all types of coverage metrics into a single database that can be accessed in an industry standard way. The UCIS facilitates the creation of a unified coverage database that allows for interoperability of coverage data across multiple tools from multiple vendors.

This presentation, intended for verification managers and tool developers alike, provides an introduction to and overview of the UCIS and how users plan to utilize it to enhance their verification flows. We provide a survey of many of the commonly-used coverage metrics and how they are modeled in the UCIS. The information that users will be able to access through the UCIS will allow them to write their own applications to analyze, grade, merge and report coverage from one or more databases from one or more tool vendors. We will also discuss the XML-based interchange format of UCIS, which provides a path to exchange coverage databases without requiring a common code library between tools and vendors.
