Its always fun to take the wraps off of solutions we have been hard at work developing.  The global team of Mentor Graphics engineers have spent considerable time and energy to bring the next level of SoC design and verification productivity to what seems to be a never ending response to Moore’s Law.  As silicon feature sizes get smaller, design sizes get larger and the verification problem mushrooms.  But you know that.  These changes are the constants that drive the need for continued innovation.  Our next level of innovation for design verification is embodied in the Mentor Enterprise Verification Platform (EVP) which we recently announced.

Gary Smith recently published Keeping Up with the Emulation Market, and lays out the fact that verification platforms are unifying with emulation now a pivotal element, not just for microprocessor design success, but for Multi-Platform Based SoC design success as well.  The need to bring software debug into the loop with early hardware concepts is a verification challenge that must be supported as well.  Pradeep Chakraborty reported on the point made by Anil Gupta of Applied Micro at the UVM 1.2 Day in Bangalore where Anil implored “Think about the block, the subsystem and the top.”  The point made was software is often overlooked or under tested prior to committing to hardware implementation implying that our focus on UVM leaves us to verify no higher than where UVM takes us – and that is not the “top” of the SoC that mandates software be part of the verification plan.

Path to Success

With the Mentor EVP, we do address these issues.  We bring simulation and emulation together in a unified platform.  Software debug on conceptual hardware is supported to address verification at the “top.”  And even as Gary’s report concludes with a wonder about how easy access to emulation will be supported for the masses.  That too is solved in the Mentor EVP using VirtuaLAB that can be hosted in data centers along with the emulator vs. complex, one-off lab setups that lock an emulator to a design and lock out your global team of software developers from collaborating.  The Mentor EVP moves to emulation for the masses in a 24×7 world.

With big designs comes big data and complex debug tasks.  These complex debug tasks are all easily handled by the new Mentor Visualizer Debug Environment that has native UVM and SystemVerilog class-based debug capabilities and low-power UPF debug support to easily pinpoint design errors. All of this works in both interactive and post-simulation modes for simulation and emulation.  To keep the software team productive, and get to SoC signoff sooner, the innovative and new Veloce OS3 global emulation resourcing technology moves software debug think-time offline to Mentor’s Codelink software debug tool.

And there’s more!  But I’ll leave that for you to discover.  When you have time, visit us here, to learn more about the Mentor Enterprise Verification Platform.

Path to Standards

As the move to support Multi-Platform Based SoC evolves, so do the standards that underpin it.  And as I’ve reported on the comments of others in this blog – and the understanding from our experience that UVM can only go so far in Multi-Platform Based SoC verification – we concluded the time is right for the industry to explore the need for new standards.

We announced at DVCon 2014 an offer to take our graph-based test specification into an Accellera committee to help move beyond the limitations today’s standards have.  As our investment in tools, technology and platforms continues, we are keenly aware users want their design and verification data to be as portable as possible.  The Accellera user community members echoed the need to discuss portable stimulus that can take you up and down the design hierarchy from block, to subsystem, to system (“top”) and support the concurrent design of hardware and software.

In support of this, Accellera approved the formation of a Portable Stimulus Specification Proposed Working Group (PWG) to study the validity and need for a portable stimulus specification.  To that end, join me at the kickoff meeting to launch this activity on Wednesday, May 7, 2014 from 10:00am to 4:00pm Pacific time at the offices of Mentor Graphics in Fremont, CA USA.  If you would to attend, or you would  like time on the agenda to discuss technology that would advance the development of a Portable Stimulus Specification or discuss your objectives/requirements for this group, contact me and I will put you in touch with the meeting organizer.  Accellera PWG meetings are open to all and do not require Accellera membership status to attend.

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).

UVM 1.2 Release is Imminent

As vice chair of DVCon 2014, I can share with you that the Universal Verification Methodology (UVM) remains a topic of great interest.  It sets the pace for tutorials and given the pending release by Accellera, learning what is new in UVM 1.2 is a compelling reason to attend DVCon.

The Accellera Day tutorial series on Monday at DVCon is popular with UVM being a session of great interest.  Aside from the “verification crisis” driving the need to explore this industry standard, the first major update is also a reason to generate this interest.  The UVM tutorial is meant for the novice and expert alike.  UVM experts can expect to walk away with more information on the new UVM 1.2 features and how they might plan to deploy them.

Naturally, I suggest you consider registering for the conference to attend this tutorial.  (There are still a few seats left; but you will need to hurry!)

UVM Working Group Discussions

As a member of the Accellera UVM Working Group, I have asked the team to consider adopting the SystemC development scheme of an open public review of a pending release of open source code.  While the merger of OSCI and Accellera to form Accellera Systems Initiative inherited the OSCI style of public review, Accellera has not fully embraced it for all its projects.

In a disclosure of a bit of insider conversation I had with the UVM WG this last week, I asked the group to confirm that we were going to bypass the “official” public review option and go to an internal 30-day review cycle only – then release to the public.  While the conclusion was to stay on the 30-day internal review path, the group also noted that one who may be familiar with Git might be able to locate the source code (and many have) and do testing.

Since the bleeding-edge users know they can access as it is being developed, why not share the Git commands for everyone to gain access?  So the group has done just this.  When last minute changes for Release Candidate 4 were put in place, the Git script to offer access for early review was shared publicly.  You can find can find this public message here, thanks to UVM WG member Adiel Khan (from Synopsys).

If you are a seasoned UVM user and are attending DVCon the week of March 3rd, I would encourage you to do some testing now so you can connect with the developers first hand.  And even if you are not attending DVCon but want to migrate to UVM 1.2, you might want to get an early start to determine what you might need to do to adopt this release.

If you are not going to attend the DVCon UVM tutorial and want a short update on what this version will offer, the UVM WG secretary, Adam Sherer (from Cadence), put together a brief slide set that he presented at the TVS DVClub event in September 2013 that you can download.  You may find it a useful companion to the download of the open source code.

Even if you are not attending DVCon, the adoption of UVM is globally substantial and it might be good to reflect on the need for broader testing.  In the first releases of UVM, this may not have been as important as few were using it and the number of tests limited to the main developers.  However, as its popularity has grown and adoption increased, it is probably a good idea for the Accellera UVM Working Group to consider the impact of a new release on teams actively using it now.  While the UVM WG drives to closure on its release candidate and the UVM 1.2 standard, you are offered the opportunity to give us feedback.  For those who have time, please do!

Mentor Commentary on Standards Development

Lastly, for those attending DVCon, check out our own Tom Fitzpatrick’s Wednesday morning paper – Of Camels and Committees: Standards Should Enable Innovation, Not Strangle It. His commentary on the development process may shed some additional light into how technology additions, changes and enhancements are judged for inclusion in updates to standards, like UVM.

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

  • 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!

The UCIS Story

There is no secret as design sizes grow it is doubly burdensome for verification.  Two factors that are easy to measure is the time it takes to simulate a design and the other is the size of the dataset that contains the results of the verification runs. Simulation times are growing and the datasets are getting larger.  While time and attention is given to accelerated verification through emulation, or alternate verification methods, to reduce run times, less explored is the impact of larger datasets on verification closure.  How does one find bugs within datasets that are so large?  How can verification results from simulation, emulation, formal and more be brought together to help drive verification closure?  How can one link failures in verification back to requirements?

The Accellera standards organization took a multi-year journey to help address these issues and arrived at the creation of the Unified Coverage Interoperability Standard (UCIS).  You can get your free copy here if you would like to read and use it.  Mentor Graphics contributed a significant starting point to the standard and collaborated with major competitors and users to add to and extend from there.  But now that the standard is done, what does one do with it?

While that was a rhetorical question when the standard was done in 2012; today it begs an answer.

From my perspective there are two classes of users of UCIS.  The more immediate users are those who are building verification tools that must contend with design and verification complexity now.  With UCIS they have the initial underpinnings to add product features that will allow a level of data portability that was not present prior to the standard.  The second class of users are those who will use the UCIS Application Programming Interface (API) to build functions that will perform simple and complex tasks on these large datasets.  This last class of user that might exchange UCIS API code with each other has yet to materialize.  But the stage is set for them.

To highlight what the first class of UCIS adopters have been doing, DVClub in Europe will tackle to answer this question as on what one can do with UCIS on Monday, 13 January 2014.  Darron May, Product Manager at Mentor Graphics will speak for us on our application of the standard.  His session is titled Blending Metrics from Multiple Verification Engines to Improve Productivity.  You can find out more details about the DVClub event (speakers and presentation abstracts) and register here to attend in person or via remote access.  The event will be held 12:00-14:00 GMT and is free.

Low Power Flow Kicks-off Symposium

In the world of electronic design automation, as an idea takes hold and works its way from thought to silicon, numerous tools are used by engineers and the like to help bring a good idea to product fruition.  Standards play a key and important role to help move your user information from high-level concepts into the netlists can be realized in silicon.  The IEEE Standards Association is holding a Symposium on EDA Interoperability to help members of the electronics/semiconductor design and verification community better understand the landscape of EDA and IP standards and the role they play to address interoperability.

Another key component are the programs and business relationships we foster to promote tool connectivity and interoperability among each other.  The Questa users rely on the Questa Vanguard Partnership program so their trusted tool and technology partners have access to our verification technology to allow them to craft the leading edge design and verification flows with technology from numerous sources.  If your users want you to connect with Questa, we invite them to explore the benefits of this program.  Even better, join us at the IEEE SA Symposium on EDA Interoperability where can also discuss this in person – Register Here!

Event Details

Download the standard now – at no charge

The IEEE Standards Association (IEEE-SA) has published the latest UPF 2.1 standard, officially called IEEE Standard for Design and Verification of Low-Power Integrated Circuits, many refer to it as IEEE 1801 or UPF for the Unified Power Format as this was the name Accellera had given it prior to transferring standardization responsibility and ongoing maintenance and enhancement to the IEEE.  Further – Courtesy of Accellera – the standard is available for download without charge directly from the IEEE.

1801-2013_Page_001The latest update to IEEE 1801 is ready for download.  It joins other EDA standards, like SystemVerilog and 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.)

The official IEEE announcement on the standard’s publication can be found here.  And the official Accellera announcement that it has partnered with the IEEE-SA to offer the standard to all at no charge can be found here.  This revision of the standard had one of the largest number of IEEE-SA entity members of any corporate standards program.  Participation from the IEEE-SA global community of entity participants ensures the needs of a broad set of companies are captured to support this worldwide standard.

Power Aware Verification Course Modules Released

I guess I could continue the puns on the low-power theme as a few readers may get a charge out of it. And there is a reason I seem to gravitate to puns from the start. The first chair of the IEEE 1801 committee and I exchanged puns one time that resulted in him shipping me a Pun DVD that recorded a pun contest in which one person and another tried to out do the other when it came to puns. So it is understandable why the topic of low power standards takes me back to these fun exchanges.

But low power design and verification is a serious issue that design teams continue to grapple. To take advantage of emerging support of the new low power standard takes time and energy on part of practicing engineers and design teams. More information on what IEEE Std. 1801™-2013 (Unified Power Format) is and how you can use it is needed.

Back in March 2013 I blogged that the revised IEEE low power standard had been approved. I also mentioned there would be a short wait until the standard itself was published. And, indeed, we continue to wait for the final editing of the standard. I shared a link to a short article on the content of the standard, but more information is needed.

PA Verificatio Intro.jpgTo address this need, the Verification Academy has added a course on Power Aware Verification. There are six (6) sessions that will introduce you to power aware verification, UPF and walk you through an example to illustrate the use of the standard in more detail in about 1.5 hours. In order to access the course material you will need to be a “full access” registrant of Verification Academy. There is no fee for this, but restrictions apply.

In addition to watching the video course sessions online, you can also download the presentations and MP4 videos of the course for offline viewing.

The six course sessions are:

We are interested to get your feedback on the Power Aware Verification course and learn what additional sessions you think would help you get AMP’ed up to further the need to conserve energy. Let us know!

IEEE 1801™-2013 Enters Pre-Publish Phase

The completion and approval of electronic design automation standards has seemed to be the order of the day for several months now.  Added to this list is the IEEE Standards Association (SA) approval of their newly revised low power standard (IEEE 1801™-2013).  The IEEE SA’s Review Committee (RevCom) unanimously recommended approval and that was confirmed by the IEEE SA’s Standards Board last week.

If you don’t recognize IEEE 1801, you may also know it as the Unified Power Format (UPF).

As with all the IEEE standards, after approval, they are sent to editorial staff to prepare them for publication.  So while you might expect me to suggest you get a copy of the standard, if low power design and verification is important to you, I know you cannot get a copy yet.  So I won’t do that.  If you do need something, the superseded version from 2009 is the only one available at this moment.  I will keep you updated as to when it is published and ready for access to the global design community.

imageMentor Graphics’ Erich Marschner and vice chair of the IEEE 1801 working group has published a short article in the DVCon edition of Verification Horizons titled Bringing Verification and Validation under One Umbrella The Evolution of UPF: What’s Next?  (Free access; no registration required; 81KB)

Erich gives a good introduction to the new standard, also known as UPF 2.1.  He describes that UPF 2.1 is an incremental update of UPF 2.0 and not a major revision. He shares that UPF 2.1 contains a large number of small changes, ranging from subtle refinements of existing commands to improve usability, to new concepts that help ensure accurate modeling of power management effects. His article describes some of the more interesting enhancements and refinements that can be found in the new standard.

Erich also shared that the 1801 working group is composed of more than 16 user and vendor companies with even many more participating in the final ballot.  This gives us good confidence in the content of this standard and that the group will be ready to tackle the next issues and emerging requirements to further improve low power design and verification.  If you are interested to join in with the IEEE 1801 team, visit here for more information.

DVCon UPF Tutorial

The IEEE 1801 leadership hosted a half day tutorial on the new standard in late February at DVCon.  For those who registered for the conference, the tutorial presentation is still available online.  Unfortunately, the material has not yet been made available to the general public.  If you know someone who attended DVCon, and went to the tutorial, you might want to see if you can borrow their copy.  The conference did an audio recording and I believe plans are to sync the audio with slides for those who were unable to attend DVCon. Stay tuned for this and I will share information when this becomes available.

As for planning you can do now.  The IEEE 1801 team will host a tutorial at DAC on Sunday.  I will share more information with you on that once the DAC registration site goes live.  Until then, I guess we all have to wait and be patient – and plan our trips to DAC in Austin, TX.
