Advanced node Re-spins: Be very afraid (maybe)
June 10, 2014  by Peggy Aycinena

 

UMass Amherst’s Sandip Kundu moderated a Thursday afternoon panel at DAC entitled, ‘Designing on Advanced Process Nodes: How many re-spins should you plan for?’

In concert with his four panelists, Broadcom’s Ajat Hukkoo, Intel’s Ashu Bakhle, Samsung’s Hong Hao, and GlobalFoundries’ Luigi Capodieci, Kundu laid out qualitative motivations and quantitative guidelines for predicting how many re-spins can be expected when a design targets next-generation geometries.

Prof. Kundu began with an homage to the costs and challenges: “Chips are expensive to develop, the Spice models are expensive to develop, and the first-pass and second-pass models often are not working.”

It’s within this environment of uncertainty, Kundu said, that designers and their managers are having difficulty predicting how many re-spins will be needed to get things right, and thus budgets and schedules are equally unpredictable.

Ajat Hukkoo agreed: “At Broadcom, every time we migrated from one node to another, the partitioning [of the design] had to be re-evaluated for electrical considerations and costs.

Guest Post: How I Spent My Three Days at DAC
June 10, 2014  by Tom Anderson, VP of Marketing

Last week, we offered Breker’s perspective on the recently concluded Design Automation Conference (DAC) in San Francisco. After last year’s DAC in Austin, in addition to our own summary we published several guest posts from other vendors in which they shared their impressions of the show. These proved quite popular, and so again this year we’ll be publishing some guest posts with interesting thoughts on DAC and how it’s evolving to meet the needs of the semiconductor industry. Today we begin with Jonah McLeod, director of corporate communications at Kilopass:

Three days of DAC as an attendee found me listening to presentations at the TSMC and SMIC booths from foundry partners. In between times, I listened to two pitches from Monte Carlo simulation vendors Solido Design Automation and CLK Design Automation. Both promised to achieve Spice-level accuracy within a couple of percentage points in a fraction of the time. I also checked out Verifyter AB, a company offering debug automation and analysis software.

Thanks to everyone that came to the 2014 Design Automation Conference.  It was a successful show with maximum traffic on Tuesday afternoon.  At the Real Intent booth we were giving away Roses (yes they were real!) and had a photo booth as well.   Visitors could dress up in world-cup soccer jerseys and hoist the World Cup 2014 Trophy.

A Fond Farewell to DAC 51 in San Francisco
June 5, 2014  by Tom Anderson, VP of Marketing

The 51st Design Automation Conference (DAC) has passed into the history books with three days of exhibits and a wide range of enveloping technical sessions and tutorials. After returning home, I’m thinking back over the week fondly as I nurse feet that ache more than I thought possible. Before I get back into the usual work routine, I want to capture some of the impressions and thoughts running through my head.

There is no doubt that  big forces in the industry are aligning toward our view of SoC verification with graph-based scenario models. Many of the people who stopped by our “USS Ice Breker” booth completely understood that they risked hitting an iceberg with their minimal full-chip verification efforts. Some had heard about Breker from colleagues or had seen us listed in Gary Smith’s and John Cooley’s DAC “must see” lists. Others knew little about us but were attracted by our claim as “The SoC Verification Company.” All wanted to know how we can help them.

 

The June breezes were intense in San Francisco this week. The fog was swirling out at the Great Highway, and making itself known across town amidst the flags flying sharply over Moscone Center. The Electronic Design Automation and IP communities were out in force in and around South Hall, while thousands of edgy app developers were playing out their own dramas across the street and down the block in and around West Hall where Apple was holding court at the same time. Fourth and Howard was awash all week in hordes and gaggles of the people who are shaping the future of the world.

Algorithms – Perhaps as never before, algorithms were the number one topic at DAC this year, and in so many different shapes and sizes. Algorithms for high-level synthesis, algorithms for creating models, algorithms for translating physical data into guidelines for design, algorithms for translating assertions into verification metrics for more orderly validations, algorithms for encrypting and decoding, algorithms for compression and decompression, algorithms for converting approximate computational output into exactitude, algorithms for hearing, seeing, and even believing. In San Francisco this week at DAC, it was algorithms all the way down, everywhere you looked.

Adjacencies – The Design Automation Conference is all about ideas, and this year the principle idea was change. The Executive Committee re-shuffled the long-standing deck of cards that’s represented the most important topics at DAC over the last 50 years and came up instead with a whole new set of talking points.
