Another Reason to Stay an Extra Day in Austin

Friday, June 3rd, 2016

If you are attending the Design Automation Conference (DAC) in Austin, Texas, June 5-9, and need a good reason to stay an extra day, look no further. Oski Technology is offering a one-day primer on advanced formal verification techniques at the DAC Decoding Formal one-day training, “Achieving Formal Sign-off”, on Thursday, June 9, from 10 a.m. until 5 p.m. at the Hilton Hotel, Austin. 

Part 2: Formal Verification Program Leader: The Critical Role of Planning and Measurement

Tuesday, May 17th, 2016

As in any engineering endeavor, formal verification involves engaging individuals in many different roles, often including formal managers and, given the technically deep and complex nature of FV, nearly always one or more formal experts. The manager of the formal verification effort on a project may have formal as his or her primary or sole responsibility, or may manage multiple aspects of verification (e.g. both simulation and FV). However, even a full-time formal verification manager may or may not drive the overall formal program in their company or organization.

In part one of this discussion, I talked about the emerging role of the Formal Verification (FV) Program Leader, an individual who enables and drives the formal process by navigating organizational dynamics, understanding designs and their verification complexities and schedules, developing and presenting ROI trade-offs, etc.; all to help achieve project goals. I listed six aspects of this role that the FV Program Leader must master in order to effectively lead the adoption and deployment of formal verification: Organization, Training and Upskilling, Test Planning, Progress Metrics, Sign-off Process, and Post Mortem Analysis.

Recap of the 2016 Oski Formal Puzzler – “Chessboard Challenge” (+ Video)

Thursday, March 24th, 2016

In December 2015, Oski challenged formal users to build the fastest testbench to solve our Oski Formal Puzzler – the Chessboard ChallengeBerkeley Math Circle Monthly Contest 8, 2011, proposed and designed by Evan O’Dorney, three-time Putnam Fellow.  Jesse Bingham from Intel submitted the winning entry, as was announced during a presentation at the recent meeting of the Decoding Formal Club in Santa Clara, CA on February 29, 2016. This was an opportunity to promote the adoption of formal verification across the semiconductor industry, and share formal techniques by showing how they might be used to solve a fun formal puzzle.

Oski Holiday Challenge – a Fun Formal Puzzler

Wednesday, December 9th, 2015

“Jingle Bells”, “Silent Night”, “We Wish You a Merry Christmas”… It has been several weeks since my youngest daughter started practicing for her upcoming violin concert. I grew up in China and missed out on the fun of Christmas festivities and holiday music. Now that we live in the United States and have had the full holiday experience, I learned that Santa Claus comes to town – two months early!

With the holiday season upon us and reflecting on the past year, 2015 has been a very busy and rewarding time for Oski. The hard work put in by each of our colleagues is paying off – with the growing adoption of formal technology and formal sign-off methodology at many companies across the globe. Formal Verification is finally coming to town!


Formal 2025: It’s Back to the Future!

Friday, November 13th, 2015

The recent Decoding Formal Club meeting hosted by Oski Technology on October 21, 2015 at the Computer History Museum in Mountain View celebrated the club’s 2nd anniversary with a “back to the future” twist.

While many of the predictions in the movie “Back to Future Part II” did not come true on October 21, 2015, the day of “the future” to which Marty McFly and Doc Brown time travel in a flying silver DeLorean sports car, that didn’t deter us from inviting attendees from Apple, ARM, Arteris, Broadcom, Ericsson, Google, Imagination, Microsoft, NVIDIA, Palo Alto Networks, Qualcomm and others to make some timely predictions for formal verification in 2025. The group was comprised of formal experts with years of experience, as well as engineers who are new to formal verification, so the predictions for 2025 were daring, but quite possible.


Happy Birthday, Decoding Formal!

Thursday, September 24th, 2015

On the radio yesterday, we heard that the song “Happy Birthday To You”, one of the most widely sung tunes in the world, was ruled by federal judge George H. King to finally be in the public domain!

This welcome news seems to come at the right time, as Oski Technology plans to celebrate the second anniversary of the Decoding Formal Club at our quarterly meeting on October 21 at Computer History Museum, in Mountain View.

Since it was founded in October 2013, the Decoding Formal Club has drawn the attention of engineers, designers and verification managers. In a relatively short time we have covered much ground, and become a forum where formal knowledge and experience can be shared among the growing community of formal enthusiasts. In turn, Oski’s featured presentations have covered many aspects of formal sign-off methodology: Bounded Proof, Abstraction Models, Formal Test Planning, End-to-End Checkers and Constraint Management.


Unbroken, 73 Bugs Captured!

Friday, June 19th, 2015

The story of Louis Zamperini, as told by Laura Hillenbrand in “Unbroken: A World War II Story of Survival, Resilience, and Redemption”, is a great testimony of the strength of human spirit. Going through unimaginable catastrophes, including drifting 47 days on the open sea with leaping sharks, thirst, starvation, and machine gun attack from a bomber plane, as well as enduring 3 years under severe and brutal conditions as a POW in Japan, Zamperini emerged unbroken with grace, humanity and love.

This is such an inspiring story that when I thought about writing about Oski DAC 2015 “Break the Testbench” Challenge results, the word “unbroken” came to mind. While this is no comparison in its scale to the story of Zamperini, the word “unbroken” succinctly summarizes the challenge result.


Preparing for Another Challenge at DAC: Break the Testbench!

Monday, May 18th, 2015

You may remember the Oski Technology Live Verification Challenge in 2012, where during the 72 hours of DAC, Oski verification engineer Chirag Agarwal formally verified a well-simulated design from NVIDIA, sight unseen, live and on camera, and found 4 corner case bugs. The challenge results exceeded everyone’s expectations, and inspired other companies to do more with formal in their verification flow. See the Live Oski Verification Challenge, and a blog recap and six-minute video, here.

The Impact of Great Teachers

Friday, May 1st, 2015

My daughter has been learning violin for the last 5 years with a wonderful Suzuki teacher. She emphasizes proper posture, beautiful tone and a good work ethic. This has built a solid foundation for my daughter to venture into learning other instruments. Last fall my daughter started playing flute for her school band, and viola at Young String Ensemble, the youngest division of Portland Youth Philharmonic, founded in 1929 as the first youth orchestra in the United States.

To help her prepare for the upcoming audition for the more advanced Portland Youth Conservatory Orchestra, we decided she would take some viola lessons with the Oregon Symphony Principal Violist. We were totally blown away after just one lesson.


New Year’s Resolution – Treading Deep into Formal

Friday, January 16th, 2015

According to statistics published in 2014 by the University of Scranton in Pennsylvania in the Journal of Clinical Psychology, 45% Americans usually make New Year’s Resolutions. And people who explicitly make resolutions are 10 times more likely to attain their goals than people who don’t.

The largest resolution category –– 47%, is related to self-improvement and education. This is me, trying to squeeze time in my busy schedule to work out and keep my brain sharp by learning new things. This year, our family joined a new health club where I can watch TED  Talks as I walk, and I am embarking on a learning journey with my sixth grader on Machine Learning & Robot Design. It has been fun!

As the Director of Marketing at Oski Technology, my New Year’s Resolution for Oski is simple –– Treading Deep into Formal. In the past 18 months, we successfully hosted five Decoding Formal Club events where we, and our invited guests, shared some of the deepest knowledge and practical experiences about formal that cannot be found elsewhere.

We have covered many deep formal topics such as Abstraction ModelsBound AnalysisEnd-to-End Checkers, and Formal Test Planning, all with the goal to achieve Formal Sign-off. Invited guests from industry formal leaders, such as NVIDIA and Broadcom, shared their experiences deploying formal. With deep formal talks, opportunities for formal networking, good food and cool gifts, Decoding Formal Club has become a magnet that attracts formal enthusiasts. It is where deep formal learning happens.

Carrying on the theme of Treading Deep into Formal into 2015, our first Decoding Formal Club meeting will be held Monday, February 9, from 11:30 a.m. until 4:15 p.m. at our usual location, the Computer History Museum in Mountain View.

We have an agenda packed with Deep Formal Talks and lots of fun! It will include talks by:

  • Vigyan Singhal, chief executive officer of Oski Technology, who will share another important topic in Formal Sign-off –– constraint management.
  • NVIDIA Principal Engineer Jon Michelson, co-author of “The Art of Verification with SystemVerilog Assertions” and “The Art of Verification with Vera,” who will present “A Practical Viewpoint on Liveness versus Safety.”
  • Ross Weber, Staff Design Engineer at ARM and author of the best paper award at the Jasper User Group 2014, who will discuss formal achievements at ARM.

While attendees tread deeply into the formal space, we will bring them back with a special invited guest Cliff Stoll. His TED Talk, “The Call to Learn” inspired us to offer one of his Acme Klein Bottles as a giveaway.  And with the Chinese New Year coming February 19, attendees will be in for Chinese flair and other surprises.

The event space can hold only 40 people, and we intentionally keep the event small to offer the best learning and networking experience. Our goal is to make it the best four hours of an attendee’s work week.

Come and join us as we Tread Deep into Formal in 2015. It will be exciting!
