Do you have a really tough verification problem – one that takes seemingly forever for a testbench simulation to solve – and are left wondering whether an automated formal application would be better suited for the task?

Are you curious about formal or clock-domain crossing verification, but are overwhelmed by all the results you get from a Google search?

Are you worried that adding in low power circuitry with a UPF file will completely mess up your CDC analysis?

Good news: inspired by the success of the UVM courses on the Verification Academy website, the Questa Formal and CDC team has created all new courses on a whole variety of formal and CDC-related subjects that address these questions and more.  New topics that are covered include:

* What’s a formal app, and what are the benefits of the approach?

* Reviews of automated formal apps for bug hunting, exhaustive connectivity checking and register verification, X-state analysis, and more

* New topics in CDC verification, such as the need for reconvergence analysis, and power-aware CDC verification

* How to get started with direct property checking including: test planning for formal, SVA coding tricks that get the most out of the formal analysis engines AND ensure reuse with simulation and emulation, how to setup the analysis for rapidly reaching a solution, and how to measure formal coverage and estimate whether you have enough assertions

The best part: all of this content is available NOW at, and it’s all FREE!

Learn more about DDA at DAC

At DAC – Mentor Graphics and Cadence Design Systems are coming together to usher in another level of productivity in verification results data access and portability with a modern design debug data application programming interface standard. We call this emerging standard the Debug Data API, or DDA for short.  We want to share more details with you in person at DAC.  Join us on Tuesday, June 9th, at the Verification Academy Booth (#2408) at 5:00pm for a joint presentation and unveiling.  And to get a bit of background and hint of what’s to come, please read on.

History: It Started with VCD

In the beginning we had VCD as the universal standard format to exchange simulation results as part of the IEEE 1364 (Verilog) standard.   Anyone trying to use VCD today on those large SoC’s or complex FPGA’s knows the size of VCD files has all but excluded this portion of the IEEE standard from use in modern design verification practice. So the question is when will it be replaced?

To ask that question today seems fine.  But I was even skeptical in the mid 1990’s when we at Mentor Graphics created Extended VCD to support the IEEE 1076.4 (VITAL) gate level simulation standard.  At that time the largest designs were around 1 million gates. While Extended VCD never became an official IEEE standard, we shared it with our ASIC Vendor and FPGA partners along with our major competitors to ensure debug data access and portability for VITAL users was on par with Verilog.  But Extended VCD also suffers the same fate of being almost impossible to support modern large designs.

Today: VCD Replaced by a Proprietary World

VCD and Extended VCD have remained static for about 20 years. But commercial simulator, emulator and other verification technology suppliers have not stopped innovating to advance support for larger design sizes with larger result data sets. As we move to 2 billion gate designs and beyond, the dependence on these private and closed technological advances and innovations has never been more important.

But that proprietary dependence comes with a cost. We stand at a crossroads where consumers of verification results information lose the open and unencumbered use offered by VCD or they need a path forward that preserves their current benefits while protecting and encouraging producers of such information to continue to innovate by private means.  The only alternative are fully integrated solutions from a single supplier that rarely get consumer endorsement in a best-of-breed; mix-and-match world.

Near Future: Federating the Proprietary World with DDA

Federating proprietary solutions almost sounds like something that is impossible to do. But Mentor and Cadence will share their emerging work on a standard to federate the different sources of verification results that can come from private sources with unencumbered access for the consumer. The Debug Data API standard will offer consumers the benefits of VCD interoperability, data portability and openness while preserving the benefits of private innovation for tool and solution producers. It will not impose data format translations from one format to another as a means to promote data portability.  It will not require the means by which one supplier or another stores verification results to be exposed.  It will offer the best of both worlds to producers and consumers.  I guess in some cases, you can have your cake and eat it too! There are more details to share, and the best place start is to meet us at DAC.

7 May, 2015

For all things verification, you will want to stop by the Verification Academy booth #2408 at DAC to interact with experts exploring the challenges of IC design and verification.  At the top of each hour, the Verification Academy will feature a presentation followed by a lively conversation.  Presentations will not be repeated so each hour will be unique.

We have themed each of the days as well:

  • Monday is “Debug Day
  • Tuesday is “Standards & FPGA Day
  • Wednesday is “Formal Verification Day

Naturally, you will find a few exceptions to those rules when you look at the program in detail.  Please register for Verification Academy sessions here: Monday Registration | Tuesday Registration | Wednesday Registration.  [NOTE: the Verification Academy sessions are highlighted with a blue background when you visit the registration site.]  A concise listing of all the Verification Academy sessions can be found here.

We will feature an end of the day reception on Monday at the Verification Academy booth after the last presentation.  Neil Johnson (XtremeEDA) and Mentor’s Harry Foster will explore Agile Evolution in SoC Verification in that last session.  The session begins at 5pm.  Neil is a proponent of this methodology as a means to to help build in design quality and simplify the task of verification.  In addition to being an advocate for this, he is also a practitioner of it.  He is an open-source hardware developer and Moderator at  We think the conversation that follows this informative session will be a lively one in which we invite everyone to continue over cocktails and hor d’oeuvres at 5:30pm.

We are sponsoring other events outside of the Verification Academy as well.  Tuesday is truly “Standards Day” at DAC.  In addition to the standards theme at the Verification Academy booth, you can kick off the day at the Accellera Breakfast and later in the day attend the IEEE DASC, Accellera and Si2 System Level Low Power Workshop.  Here is a partial list of Standards Day activities:


If you have not yet registered for DAC, do so now.  If you do not have plans to register for the full technical conference, many conference events are fee free if you select the “I LOVE DAC” registration option before May 19th!  In fact, all the “Standards Day” events listed above are free with early I Love DAC registration. Simply click here and you will be taken to the “I Love DAC” location to register.  Register before May 19th as after that date a $95 minimum fee sets in.

See you at DAC!

3 April, 2015

It is always good to pause to recognize the companies and individuals with whom we collaborate to create the verification flows and solutions that allow the simplest and most complex devices and systems to come to life.  It is this time of year when the fruit of collaboration has generally been shared publicly.  This is probably the case, in no small part, to the nearing of the annual trek to the Design Automation Conference (DAC).  As we get closer to that week in June this year, I will discuss it even more.  But now I would like to offer a look back at two major milestones around this time of the year that shaped our future.

20 Years Ago

On April 3, 1995, we announced “Device Vendors Providing Library Support to Mentor.”  Our ModelSim simulator gained support from 12 ASIC and programmable logic vendors.  Until then, Mentor’s gate-level simulation was provided by QuickSim and its large collection of ASIC vendor libraries and flows.  With the emergence of VITAL (VHDL Initiative Towards ASIC Libraries) and as an IEEE standards project for it (1976.4) emerged, we continued our activities to drive knowledge about VITAL and educate and help the rest of the ASIC vendor community so they could bring to market their own simulation libraries for ModelSim.

As we added Verilog to the language mix, those Verilog libraries were likewise qualified and offered to the mutual customers we shared with our valued ASIC Vendor partners.  ModelSim grew to be a very popular product and the value of collaboration taught us the importance of shared collaboration.

10 Years Ago

In mid May 2005, we launched our Questa Vanguard Partnership (QVP) program modeled on the ModelSim program.  SystemVerilog 3.1a had been released by Accellera and was in the final stages of IEEE certification which was to come in November 2005.  But to get a jump on solidifying business relationships with our partners and to encourage support of SystemVerilog we began to work with companies around the world who expressed an interest to build a vibrant ecosystem.  A lot was accomplished in the six months between the launch of the QVP program to the approval of the first IEEE SystemVerliog 1800-2005 standard.

But it was good to pause then too and celebrate the standard with our new Questa partners, our mainstay semiconductor library partners and competitors in Japan.  Upon IEEE approval of the standard, Accellera in conjunction with the Big-3 EDA companies and CQ Publishing (Japan), held a “Happy Birthday” celebration reception.  I have to offer special thanks to my friends at Synopsys for the idea.  And, yes, we all know that this November will be lucky 10 years for SystemVerilog and we have already started to discuss what can be done at the annual fall standards meetings in Japan to celebrate this milestone.

Tomorrow (DAC)

As I mentioned, the great thing about this time of the year is the planning for DAC.  Many good things have happened in the last year.  Last year, at Mentor Graphics’ urging and our public commitment to donate technology, Accellera started a “Proposed Working Group” on Portable Stimulus to determine the viability of a standards project.  Accellera formally approved the formation of the Portable Stimulus Working Group in December 2014.  At the Verification Academy booth at DAC, we will certainly offer updates on this work and affirm our sustained commitment to the development of this standard.  I will share full details about what, when and where for the Verification Academy booth at DAC later.

But wait!  There will probably be more.  I can assure you, I will post a few more times during this final two-month journey to DAC.  And as the daily program for the Verification Academy booth is finalized, I will share its content my thoughts on this.  And as industry events, like the Accellera DAC Breakfast are finalized, I will make this part of my commentary on DAC 2015 as well.  It seems this DAC will be a busy DAC.

But this is something you can do now!  If you don’t know if you want to attend the technical program yet, you should at a minimum secure a free pass to the exhibit floor and access to some open industry events.  If you register by May 19th, you can choose the “I Love DAC” registration – complements of ATopTech, Atrenta, and Calypto.  After May 19th, it is no longer free.  So why not register now?  I look forward to seeing you at DAC.

“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 ), 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 ), 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?

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.

Live & In-Person at DAC 2012!

DAC 2012 4Verification Academy, the brain child of Harry Foster, Chief Verification Scientist at Mentor Graphics, was live from the Design Automation Conference tradeshow floor this year.  Harry is pictured to the right giving an update on his popular verification survey from the DAC tradeshow floor.

The Verification Academy, predominantly a web-based resource is a popular site for verification information with more than 11,000 registered members for forum access on topics ranging from OVM/UVM, SystemVerilog and Analog/Mixed-Signal design.  The popular OVM/UVM Cookbook, which used to be available as a print edition, is now a live online resource there as well.  A whole host of educational modules and seminars can also be found there too.

If you know about the Verification Academy, you know all about  the content mentioned above and that there is much more to be found there.  For those who don’t know as much about it, Harry took a break from the being at the Verification Academy booth at DAC to discuss the Verification Academy with Luke Collins, Technology Journalist, Tech Design Forum.  (Flash is required to watch Harry discuss Verification Academy with Luke.)

The Verification Academy at DAC was a great venue to connect in person with other Verification Academy users to discuss standards, methodologies, flows and other industry trends.  Each hour there were short presentations by Verification Academy members that proved to be a popular way to start some interesting conversations.  While we realize not all Verification Academy members were able to attend DAC in person, we know many have expressed an interest to some of the presentations.  Verification Academy “Total Access” members now have access to many of the presentations.






Thales Alenia Space


Test & Verification Solutions


Willamette HDL

Accellera Ushers in Unified Coverage Interoperability Standard (UCIS)

For the past few months, Accellera’s Unified Coverage Interoperability Standards working group has completed and released a new standard that is destined to help boost verification productivity and efficiency.  Verification teams use a variety of verification technologies, many times from different suppliers, to achieve their verification goals.  Collecting information on how each tool adds to verification closure and sharing this information for ever larger designs among different tools has become a daunting challenge.

As a precursor to addressing this from a standardization point of view, many companies built their own way of collecting and sharing this information.  Users recognized the need for a standard and market participants responded.  For Mentor Graphics part, we developed and deployed the Unified Coverage Database (UCDB) technology for our verification products several years back.  Via our Questa Vanguard Partnership program, many partners have integrated into the UCDB to help drive further verification efficiency and productivity for mutual customers.

Yet, users were still left with the challenge to use the emerging coverage database technologies from multiple vendors.  Those users sought a solution to this dilemma from Accellera.  After users completed a requirements document that outlined their needs, we at Mentor Graphics noted that our UCDB technology offered a good match.  We offered to seed the standards development with our tested technology, as did other suppliers.  In the end and with extensions from consultations with other suppliers, an updated UCDB Application Programming Interface (API) specification from Mentor Graphics formed the basis from which Accellera created the UCIS API standard.

UCIS CoverpageIn July 2008 we announced the Mentor Graphics technology donation to this Accellera standards effort.  And on the day Accellera announced completion and availability of the standard at DAC 2012, Mentor Graphics was the first to announce product support.

To read more about support of UCIS and how it plays a critical role in verification, you may wish to read the article in the DAC issue of Verification Horizons.

The UCIS co-chair, Dr. Richard Ho from D.E. Shaw Research presented a comprehensive overview of UCIS at DAC.  Dr. Ho along with his co-chair, Dr. Ambar Sarkar of Paradigm Works, Inc. also presented a tutorial at DVCon 2012 titled An Introduction to the Unified Coverage Interoperability Standard.  The tutorial is available online.  Accellera does require registration for the tutorial.  The DVCon 2012 website on the UCIS tutorial goes into detail about what is covered in this 1 hour presentation.

I highly recommend you register and watch the DVCon 2012 tutorial for a good overview of UCIS.  You can also download, for free and without registration, your copy of the Unified Coverage Interoperability Standard here.  It makes a good companion for the tutorial.

What will you do with UCIS?

After reading the standard and watching the tutorial you should have a solid understanding of the importance it plays to reach coverage closure.  You will learn how you can create applications to improve your own verification productivity and efficiency.  Do you want to share the applications you write?  The new UCIS forum and contribution area was created just for this purpose by Accellera.  Please visit the site, register and contribute.

As more users begin to adopt UCIS, I envision this site will provide a good site for users to share applications.

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.
