The Secret Decoder Ring for Formal Analysis

Wednesday, October 28th, 2015

Those of us of a certain age will remember the secret decoder rings promoted by various products and TV shows. They generally used a simple substitution code to map letters to numbers. According to Wikipedia these have been offered as recently as 2000, so perhaps they are known to younger readers as well. What’s germane to today’s blog post is that formal services company Oski Technology has cleverly used this device as a graphical element in promoting its “Decoding Formal” Club series.

I’ve reported before from these events, which I believe have been very effective at advocating for formal analysis, sharing tricks and techniques, and demystifying what was once regarded as an arcane academic approach to verification. Last week I attended another Decoding Formal Club forum and, as usual, was impressed by the depth of the presentations. Since formal is always a popular topic among readers of The Breker Trekker, I’m going to share a few highlights from that afternoon.

Decoding Formal Club Unlocks Some Mysteries

Tuesday, March 10th, 2015

Last May, I published two blog posts on the presentations made at a “Decoding Formal Club” event hosted by the smart folks from Oski Technology at the Computer History Museum in Mountain View. With everything else going on, I didn’t manage to make it to another of their regular meetings until last week. The first event of 2015 was very interesting, so again I’m returning to the popular topic of formal analysis and playing reporter. The line between media and blogging is rather thin these days anyway.

This edition of Decoding Formal featured three talks, one an end-user case study and the other two  instructional in nature from well-known formal experts. I found all three worthwhile and will do my best to communicate some of the main points made. I also have to mention the final presentation, more a performance than a talk, by the inimitable and irrepressible Clifford Stoll. Lately he’s been manufacturing and selling Klein bottles, which you may remember from a geometry teacher trying to mess with your mind.

Final DAC Roundup: Spotting Trends and Catching Frisbees

Monday, June 23rd, 2014

Over the last few weeks, we’ve provided a look back at DAC from Breker, Jonah McLeod of Kilopass, and verification consultant Lauro Rizzatti. Today we wind up the series with some great insights and memories from five more DAC exhibitors.

For formal verification services provider Oski Technology, DAC confirmed what it’s experiencing: use of formal adoption is on the rise worldwide, notes Jin Zhang, its senior director of marketing. As is often the case, along with adoption comes the need for training and that’s certainly true for formal verification. Attendees and exhibitors alike stopped by the Oski booth to ask about advanced formal training. Yes, Oski offers several types of training customized to specific needs, and verified that DAC can be a great place to raise awareness and visibility.

Building a Productive Team for New Verification Approaches

Tuesday, May 6th, 2014

Last week I used a talk by Vigyan Singhal, CEO of formal consulting experts Oski Technology, as the springboard for a blog post on how to extend verification planning for formal analysis and graph-based SoC verification. This week, I’m using a panel held at that same “Decoding Formal Club” meeting as the starting point for my thoughts on how to establish an effective team to use relatively new verification technologies such as formal and graphs.

The second half of the meeting was a panel on “How to Build a Productive Formal Team” moderated by Harry Foster from Mentor. The participants included a nice mix of users, while Vigyan rounded out the panel with his unique blend of formal tool development and hands-on usage with many customers. Although there wasn’t much controversy per se, it was clear that everyone had different experiences leading to different opinions on how to build a strong formal team.

Extending Verification Planning to Formal and Graphs

Tuesday, April 29th, 2014

Last week I mentioned that I attended the third “Decoding Formal Club” meeting sponsored by formal consulting experts Oski Technology. I started out to write about this event but was distracted by the big news that Cadence had acquired formal leader Jasper Design Automation for $170M. As the meeting was winding up, a friend from Mentor picked up the news alert and showed it to me. I pulled up the news on my own smartphone and showed it to Vigyan Singhal, CEO of Oski and also the original founder of Jasper.

So I had the pleasure of informing Jasper’s founder that his old company had been acquired. But I don’t want to let that bit of fun or the Jasper news in general to lead us to forget about the Decoding Formal meeting. There were two primary segments: a presentation from Vigyan on verification planning and a panel of expert users on building a formal team. I’ll talk about the presentation today and cover the panel in a future post.
