Synopsys’ Stelios Diamantidis Is Bringing the Magic of AI To Chip Design

Moore's Lobby: Where engineers talk all about circuits

“It’s a magical world.” After several decades in the chip design industry, Stelios Diamantidis might be just as fascinated by the work he gets to do today as when he saw his first computer as a child growing up in Greece.

Inspired by the success of computers and AI systems in defeating humans in strategy games like chess and Go, Diamantidis wondered, “what if we were to one day be able to treat chip design as a game, a very complex game?” Armed with that question, Diamantidis and his Synopsys colleagues got to work.

Eventually, that led to their DSO.ai (design space optimization using AI) product. As Diamantidis explains in the interview, they started on smaller challenges in the IC design flow and have expanded over the past few years. “I'm extremely excited that this...technology has provided a framework for all of them, no exceptions so far, to actually come up with great solutions.”

When discussing IC design optimization, Dimantidis states, “everybody has their own definition of the problem.” CPU designers want to optimize speed, GPU designers are focused on reducing energy consumption, and flash memory designers “are very paranoid about size because they're going to manufacture tens or hundreds of millions of units.”

In this Moore’s Lobby interview with host Daniel Bogdanoff, Diamantidis shares his experiences at an early pioneering tech company working with “some of the most remarkable folks I’ve ever met” while solving problems that were “the stuff of science fiction.” He also shares insights from founding two different EDA technology companies of his own.

Here are a few other interesting stories and anecdotes from this fascinating interview with Diamantidis:

-How some life decisions come down to snow versus palm trees

-About how budding computer programmers in Greece used to share their code through a print magazine—our younger audience might find that hard to believe

-What Jurassic Park, US President Bill Clinton, and Stelios’ early dreams have in common

-It’s not really what you miss, but what you don't know you miss

There is much more, so go listen for yourself!

Seeing the Big Picture of Vehicle Electrification with Texas Instrument’s Fern Yoon

Fern Yoon always enjoyed learning how things work. However, like many, or even most, electrical engineers, she grew up with a very limited understanding of the profession. Even through college, she still had a narrow understanding of what engineers actually do on the job. (Hmm...maybe this is why attracting people to engineering careers is difficult?).

After beginning her career with Texas Instruments as a thin film process engineering intern, Fern had the opportunity to go on a job rotation where she could see there were “a lot of different roles that existed that I honestly didn't realize.” This experience opened her eyes to a new world of possibilities and find her true satisfaction in working with customers and being able to take in the big picture.

Fern’s excitement comes across as she discusses working as a fab engineer, helping build a ruggedized laptop, and in her current position working on vehicle electrification.

When I started working in automotive ten-plus years ago, cars had a big emphasis on sustainability, emissions, and of course, reliability. Fast forward ten years, the cars are starting to look like a supercomputer on wheels.

In her 15 years at TI, Fern has steadily worked her way up the ranks and learned a lot of valuable lessons about working in teams, collaborating with customers, and charting your career path. In this second episode of All About Circuits’ coverage of women in engineering month, Fern provides interesting insights and anecdotes that you will not want to miss, including: -How vehicle electrification is probably impacting more in our cars than you imagine -Why electrical engineering was “the lesser of four evils” -Her best advice to engineers -Why you shouldn’t be afraid to learn that you don’t like something

From Apple to OpenLight: Silicon Photonics and Integrated Lasers with Dr. Tom Mader

I’ll bet that you didn’t know that the original concept for what became the Apple Thunderbolt interface involved optical communication. Well, in this fascinating podcast with Dr. Mader, you will learn that intriguing backstory and much more.

Mader also provides a helpful introduction to silicon photonics technology and applications. Importantly, OpenLight’s business model is designed to allow them to become an Arm-like IP provider for silicon photonics. “We’re the first open siliconics platform that has the lasers and amplifiers integrated on the chip,” explains Mader.

With the OpenLight Process Design Kit (PDK), customers can integrate InP lasers and amplifiers directly into their silicon IC designs at Tower Semiconductor. While the silicon can be employed to guide, modulate, and detect light, you need the InP to amplify. OpenLight literally brings the silicon and the InP together with molecular bonding.

While silicon photonic is already making inroads in a number of important applications, Mader is “excited about the long tail of applications” enabled by OpenLight and their customers.

In addition, Mader recounts his rich technology background that includes developing a patent while interning at Apple, being involved in an early Amazon commercial product, directing engineering at a startup that was inquired by Intel, and his family connections to the legendary Fairchild Semiconductor and our podcast’s name inspiration, Gordon Moore.

So, listen in for other interesting tidbits from this discussion with Mader, including these technical insights:
