IEEE Std. 1666™-2011 Available as Free Download

In November 2011 I blogged the IEEE Standards Association (SA) approved a revision to the popular SystemC standard, known officially as IEEE Std. 1666™-2011.  One of the key elements of this standard includes the addition of Transaction Level Modeling (TLM).  I pointed to several online resources to learn more about the revised SystemC standard in that blog.  But missing from the list of resources was information on how to get the revised standard from the IEEE.  As I concluded my blog, I indicated that the final editorial review and formatting for publication was underway and that I would report back when this work was completed.

IEEE Std 1666-2011I can report that the IEEE SA concluded their editing of the specification and it is now ready for download.  Many of you know the prior version of the SystemC standard was available for free download and have wondered if this would be the same for this revision update.  The good news is the revision update is available as a free download as well.  If you wish to have a printed and bound copy, that too is available, but that will have to be purchased.

IEEE Std. 1666-2011 is part of the “IEEE Get Program” that offers individuals the ability to retrieve, download and print one copy of the standard for free.  Click on the link above to get your personal copy of the standard.  You will need to share some basic information with the IEEE on your user type (Academic, System/Semiconductor Company,  EDA Company, IP Company or Other).  This is certainly worth if for a free copy.

The original standard, IEEE Std. 1666™-2005, had more than 50,000 free downloads since it was made available and I expect this version to do even better.  With the addition of TLM to the standard and the move up in abstraction to handle system design requirements, the need for this standard is even more pressing today.

IEEE Announces Revision to IEEE 1666™ – Adds Transaction-Level Modeling Support

A significant step forward to address standards for advanced system-on-chip (SoC) designs has taken place by the IEEE.  The IEEE announced the new revision of the SystemC standard, known as IEEE 1666™-2011, has been approved.  While it is a revision of the current SystemC standard, IEEE 1666™-2005, the major new feature added was Transaction-Level Modeling (TLM), which is new to an IEEE standard.

For many years now, the TLM specification and accompanying open source code has been incubating in the Open SystemC Initiative (OSCI).  OSCI’s TLM Working Group has developed the TLM 1.0 and TLM 2.0 specifications, both of which are part of the revised IEEE 1666 standard.  TLM is important to SystemC, but it has also been leveraged outside of it.

We at Mentor Graphics pioneered the use of TLM in SystemVerilog (IEEE 1800™-2009) when our seminal open-source work on the Advanced Verification Methodology (AVM) brought an implementation to the verification community based on SystemVerilog.  This lives on today, as AVM motivated the Open Verification Methodology (OVM), which became the basis for Accellera’s Universal Verification Methodology (UVM).

If you don’t already know what TLM is and how the verification community is using it in OVM and UVM, the Verification Academy has a lot of written material and video training modules that will help you learn how this important new IEEE standard is used from simulation to emulation and has boosted verification productivity.  The “Understanding TLM” module is featured in the Advanced UVM section, so if you are still a novice to UVM, you may wish to start with the Basic material first.  This module is presented by fellow Verification Horizons Blogger, Tom Fitzpatrick and offers subtitles in English, Russian, Japanese and Chinese (Traditional & Simplified) to help drive rapid global adoption.

As we brought TLM into the modern verification methodology practice with a SystemVerilog implementation, it also surfaced that there is an opportunity for the creator of TLM, OSCI, and an adopter of it in UVM, Accellera, to discuss what they could do together.  And as I’ve blogged before, those two organizations announced their intention to unite before the end of 2011, as others have seen the potential when both are brought together.  I expect to see more great ideas come from these two groups when they join forces, just like the TLM work that is now an IEEE standard.

For those who want a copy of the revised IEEE 1666 standard, it is still in final IEEE editorial review as the they do their last formatting.  I will share with you when it is ready to use as well as how to get it and where to find it.

System Standards Worlds Initiate Unification

accellera SystemC Logo

Accellera, who brought us SystemVerilog, and the Open SystemC Imitative (OSCI), who brought us SystemC have made known their intent to unite to form a single front-end electronic design automation (EDA) standards organization.  You can read their joint press release here.

While this may come as a surprise to many, one thing has remained constant for many years: the two organizations have had a long standing policy of collaborative interactions as both have evolved their standards programs.  At a DATE 2004 panel titled “SystemC and SystemVerilog: Where do they fit?  Where are they going?,” technical members of the two communities gathered to ponder answers to those questions.  At DAC 2004, when I was chair of Accellera and Guido Arnout was chair of OSCI, we stood before a large assembly of SystemC users a few months later to point to what was not so obvious to many, SystemVerilog and SystemC complement each other.

DAC Slide 5

Guido and I dispelled any issues of a “language war” and focused on what the value each language and what it delivered to the design and verification community.  A lot has transpired since then.  Both SystemC and SystemVerilog are now IEEE standards, know as IEEE Std. 1666™ and IEEE Std. 1800™ respectively.  And both OSCI and Accellera have continued to evolve their standards work program in significant and meaningful ways.

In this evolution, it became clear to me that each organization was “completing” the other.  OSCI has developed the popular Transaction Level Modeling (TLM) standards and Accellera had adopted TLM in their Universal Verification Methodology (UVM™).  As the technical teams from each organization have leveraged each other, it began to make more sense to initiate discussions to unite the two groups to address further front-end EDA standards challenges – as one. And, indeed, the two organization recognized this and have taken the steps to determine how best to combine operations into a single organization.

In the months ahead, the unified organization will emerge, but for now, it is business as usual for the standards development teams in OSCI and Accellera.

What do you think about the unification?

How do your favorites rank?

Have you ever wondered how popular the different IEEE standards for electronic design automation are? Have you ever wondered which ones show the least interest? When buying books online, popular book buying websites sites will rank customer purchases. Many newspapers manage lists that you can consult to determine what is the most popular; what has the highest demand. But if you have purchased any IEEE standards, you will know this information is not available from the IEEE Store or the IEEE XPlore platform.

On May 4th, the IEEE Standards Association announced its collaboration with Techstreet to create the New IEEE Standards Store.  Until now, anyone who wanted to order a single standard had to use a more complex system that even made it hard to share a permanent link to one’s favorite standard with another.  Just look at the Accellera homepage for an example of where to get the SystemVerilog (IEEE Std. 1800™) standard.  At the writing of this blog, it simply points to  [I will share the fact the IEEE’s new site now has fixed links that can now be used to help others find the most current SystemVerilog standard with the Accellera.]

But back to what is the most popular IEEE EDA standards… Any guesses?

Before I delve into those details, let me say the ranking is just by ordinal.  The New IEEE Standards Store shares no information on the actual number of standards purchased.  So the difference between #1 and #10 could be just 10 copies.  It probably isn’t, but it could be.  But talking about #10, why is it even on the list?  The IP-XACT standard (IEEE Std. 1685™) is available for free under the IEEE Get Program.  Under this program you can download a PDF of the IEEE standard for free.  If you want a printed version, you can print your own copy from the free one you download.  Back in December 2010, Accellera reported that since the IEEE started to offer IP-XACT for free, there had been 1200 downloads.  It also looks like many people did not want the hassle to print and simply ordered the print version directly from the IEEE.  The other IEEE EDA standard offered free is SystemC©  And this is probably the reason it is in 32nd place.  It is very popular in terms of the number of free downloads.

And yes, if you search for the those two standards on the New IEEE Standards Store, you will find you can order print copies there and if you read the small print below, you will see there is a link to take you to the free online versions.

Harry Foster has issued several research reports on the popularity of one language or format the past several months.  In his last blog, he discussed which of the design and verification languages are ranked high and those, well, not so high.  And I guess I feel best to share the correlation between his findings and these more “anecdotal” results from the New IEEE Standards Store.  I have been party to many at the top standards  (Verilog/SystemVerilog) and party to the “least highest” (yes, I can’t say the least liked) VITAL 2000.  For vindication, I will note that VITAL-95 comes in at #18.  In whole, it appears to me that the New IEEE Standards Store ordinal rankings of EDA standards matches the scientific data from the research Harry has reported.

Below is the full ranking of IEEE EDA standards.  Where are your favorites?

Learn more about the New IEEE Standards Store

There is much more to the New IEEE Standards Store than just the rankings of the standards we use in electronic design automation.  As I mentioned, it is easier to share fixed links to IEEE standards.  And if you want to track IEEE standards development – and don’t want to have to register your email address with the actual committee developing it just to know when they are done and a standard is ready – you can register to be notified when a new standard is ready.  The New IEEE Standards Store will notify you when a new one is ready.

Check out the short, one minute, video below to learn more about the New IEEE Standards Store.

The standards developing organizations defining and updating front-end EDA standards will be at DAC in force.  And from the looks of if, they are getting an early start to DAC with updates on IEEE, Accellera and OSCI standards at Sunday workshops.  The Sunday workshops may be of particular interest to verification engineers interested in UVM and systems designers interested in SystemC AMS.

Following the workshops, there will be a half-day meeting of the North American SystemC Users Group on Monday where users will share their SystemC experiences.  The following morning, Accellera will host its annual DAC breakfast where the UVM users will meet to share their experiences.  A lively conversation is expected.

Sunday – June 5, 2011

systemc_amsDAC Workshop on Using the Power of the SystemC AMS Extensions

Time: 10:00 AM — 6:00 PM
Location: San Diego Convention Center Room 33B
Summary: Today’s embedded systems interact more and more tightly with the analog physical environment; where digital HW/SW subsystems become functionally interwoven with analog/mixed-signal (AMS) blocks such as RF interfaces, power electronics, or sensors and actuators. Examples are software defined radios, sensor networks, automotive applications, or systems for image sensing. This requires new means to model and simulate the interaction between AMS subsystems and HW/SW subsystems at functional and architecture levels. Especially for this purpose, the SystemC language standard has been extended with powerful AMS capabilities to tackle the challenges in heterogeneous electronic system-level (ESL) design. You will get a good working knowledge of SystemC AMS by attending the workshop.

Registration: This is an official DAC sponsored event and DAC registration required.

Watch DVCon Co-Located Event Presentations

Two presentations from the second annual SystemC Day at DVCon 2011 are available now.  The first presentation is the keynote by Jim Hogan, serial EDA entrepreneur at Vista Ventures, LLC and the second is an introduction to the emerging IEEE Std. 1666™, SystemC standard by Jim Aynsley at Doulos.  SystemC Day brought users together to discuss the current state of the market for ESL design and the pending content of the SystemC standard that is current in final ballot by the IEEE.

To view the video presentations, you will need to register with the Open SystemC Initiative.

Jim Hogan, Vista Ventures LLC, California, USA
Keynote Presentation: “Navigating the SoC Era”

Abstract: SoCs are becoming ubiquitous in semiconductor development. Further, these SoCs are no longer processor-centric, and they are differentiated through the integration of design elements such as multi-CPU, multi-core, DSP cores, hardware accelerators, peripherals and software.

Industry expert and private investor Jim Hogan will discuss the semiconductor industry’s growing adoption of SoC design, and its reliance on diverse sources of hardware and software IP, developed both internally and externally.

John Aynsley, Doulos Ltd., UK
The New IEEE 1666 SystemC Standard

Abstract: The IEEE SystemC Standard is currently being revised and updated, with the new standard due to be published later in 2011. This new version of the SystemC standard will for the first time include the TLM-1 and TLM-2.0 libraries. Meanwhile, OSCI is working to ensure that the SystemC Proof-of-Concept simulator tracks any changes to the IEEE standard. This presentation will give a concise technical summary of the most important new and revised features in the SystemC standard, will give a behind-the-scenes insight into the rationale behind the changes, and will show examples to illustrate the new features in action.

systemcday2011curveOpen SystemC Initiative Tackles the Future

If you have examined the DVCon program, you know that it is a week full of the Universal Verification Methodology (UVM).  And I certainly encourage those with an interest in UVM to attend the Monday tutorial and the technical conference the next few days.  But you may also want to bring a colleague to attend the SystemC Day activities.

For SystemC Day at DVCon, the morning session is the North American SystemC Users Group (NASCUG) meeting that features a Keynote presentation by industry luminary Jim Hogan.

Jim HoganJim’s keynote will be on “Navigating the SoC Era.”  NASCUG attendance is free, but you need to register to attend.

Jim Hogan will discuss the semiconductor industry’s growing adoption of SoC design, and its reliance on diverse sources of hardware and software IP, developed both internally and externally.

After considering recent survey data on both IP and verification drivers, Hogan will discuss the challenges that design and verification teams face for impacted areas such as design assembly and verification.

In the afternoon, a tutorial on software-driven verification titled Software-Driven Verification Using TLM-2.0 Virtual Platforms will be presented by experts from the OSCI, Accellera and the user community that are using standards-based methodologies in production today.  The afternoon tutorial requires registration at the DVCon website.  The tutorial is free for conference attendees.  A small fee is charged for those who wish to attend this tutorial only.  Is software-driven verification in your future?  Chances are highly likely it is and I suggest you look at attending this event.

I’ll see you there!
