Mentor ESL in TSMC Reference Flow 12

Posted Jun 6, 2011, by Thomas Bollaert

One year ago, I was writing about the inclusion of Mentor ESL in the TSMC Reference Flow 11, and why the endorsement of system-level design and high-level synthesis by the world’s leading foundry was a telling sign of maturity for ESL. Since this first major milestone, TSMC and Mentor haven’t remained idle, on the contrary. Both parties teamed-up to take this first ESL flow to a whole new … Read More

48th DAC - Gary’s Magic Formula

Posted Jun 6, 2011, by Thomas Bollaert

Last night, in his traditional DAC-opening presentation, Gary Smith addressed the crowd with a loud and clear message about the cost of doing hardware design. Design costs are steadily increasing and this is draining life and blood out of the industry. When chip design costs reach $25M, VCs stop funding start-ups. When costs reach $50M, continued Gary Smith, even IDMs struggle to afford ASIC developments. So … Read More

DAC: 9th ESL Symposium

Posted May 16, 2011, by Thomas Bollaert

If you are going to DAC this year, then you must attend the 9th Annual ESL Symposium and not just because there is free lunch or you need the new Apple iPad 2. This year, Wally Rhines will moderate a very impressive panel line-up: Gadi Singer - Intel Vice President, Intel Architecture Group General Manager, System-on-Chip Enabling Group John Goodenough - ARM Vice President of Design Technology and … Read More

HLS Fundamentals / Part 2

Posted Apr 25, 2011, by Thomas Bollaert

In my last two posts, I introduced the question that proved the most challenging in the HLS Bluebook quiz (here) and presented some fundamental concepts about loop unrolling and loop pipelining and explained why answer 2 was not the right one (here). Let’s now see what happens in the case of answer 1, when we unroll LOOP0 by 4 and pipeline the design with II=1. Partially unrolling by 4 means … Read More

HLS Fundamentals: Loop Unrolling and Loop Pipelining

Posted Apr 19, 2011, by Thomas Bollaert

The dust has settled and four winners have emerged from the HLS Bluebook contest, and this week, as promised, I will discuss the question that proved to be the most challenging in third and final round of the contest. The culprit was the following question, which only 15% of the contenders answered correctly: HLS Contest - Round 3, Question 1 What this simple C code does is: reading 8 input values … Read More

HLS Contest: And the winner is...

Posted Apr 11, 2011, by Thomas Bollaert

Early December, the Catapult team launched the HLS Bluebook Contest. Our intent was to bring the community together around a fun yet challenging event and give people an opportunity to learn about HLS and test their skills in this area. Today, 4 months, 3 rounds and 15 questions after the grand opening, we are very happy to announce the winners of the contest, the four only individuals who score perfectly … Read More

A Designer’s Perspective on ESL Methodologies for an OFDM Modem Design

Posted Apr 5, 2011, by Thomas Bollaert

“In recent times, ESL design methodologies have been the talk of the semiconductor design community and have found increasing acceptance. Most of the recent publications have given information on design flow needs and an high level overview of the (C/C++/SystemC) based high level synthesis design process using a small block level design scenario. Although productivity benefits for ESL methodologies … Read More

Catapult C and the 7 Samuraïs

Posted Apr 1, 2011, by Thomas Bollaert

You may have already encountered the expression “Full-Chip High-Level Synthesis” on this blog. I typically define it as the ability to model, verify and synthesize complete IP subsystems starting from C++/SystemC. This obviously encompasses core processing functionality, but also control-logic, memories, hierarchy, complex interfaces and interconnects. In other words, being able to do the … Read More

The Why, What and How of HLS @ DATE 2011

Posted Mar 7, 2011, by Thomas Bollaert

Good news for the industry: the DATE (Design, Automation, and Test in Europe) conference is back to growth. And perhaps it is not a surprise given that this year the event is being held in Grenoble. With its great views on the snowy Alps, Grenoble is emerging has the major hub of the electronic and semiconductor industry in Europe. 3D ICs, Low-power, ESL… The rich conference program covers all hot … Read More

DVCon: Wally Rhine's Keynote

Posted Mar 1, 2011, by Thomas Bollaert

“50 years from today, every man, woman and child in India will be required to run an HDL simulator”. As Wally Rhines explained in his DVCon keynote today, this is the absurd conclusion you reach if you extrapolate data showing that between 2007 and 2010 the average verification team size grew by a whopping 58%. Indeed the conclusion is absurd, but the image is strikingly powerful.  Verification … Read More
