The SDV and Its Unintended Challenges

The SDV and Its Unintended Challenges

By Junko Yoshida

The software-defined vehicle (SDV) is “all the rage,” if you are to believe press-release headlines and media coverage (including this publication).

A voice of prudence is Phil Koopman, professor at Carnegie Mellon University, who recently published an article, “Architectural Coupling Killed the Software Defined Vehicle” on his Substack newsletter.

Despite its provocative headline, Koopman writes, “I don’t think the SDV is actually dead.”

However, as carmakers stampede toward the SDV cliff, Koopman warns that they might be throwing together vehicle architectures that inevitably become too complex to manage.

Can AI pave the way for multi-die systems?

Can AI Pave the Way for Multi-die Systems?

By Ron Wilson

What’s at stake:
There is growing discussion of AI in chip design. Could this be mainly marketing, or could it reflect a new weapon in the EDA armory? If the latter, AI could take on some of the most intractable challenges of designing multi-die systems.

Global industry is placing huge bets that artificial intelligence will create a step-function increase in productivity. From customer service to materials handling, from bond trading to medical research, this faith thrives across a broad domain. But what exactly do these faithful mean when they say AI? There are many species in that phylum. And how exactly will AI — demonstrably excellent at pattern recognition and parlor games, but with fundamental limitations when it comes to accuracy and predictability — make knowledge workers more productive?

The EDA industry, with its witheringly complex tasks, massive data sets, vastly skilled practitioners, and utter intolerance of error, offers an excellent laboratory for exploring these questions. The emerging field of high-performance multi-die modules in particular includes some of the most formidable challenges. And among the tasks in this area, the challenge of multi-physics analysis of modules — analyzing the interacting electromagnetic, thermal, and mechanical properties of a module design — can be most daunting. This may be a great place to ask our questions.

Maelstrom of Change Hitting Automotive Industry

A Central-Compute SoC for SDVs? Really?

By Junko Yoshida

What’s at stake:
Consider the Volkswagen Group’s desperate move to partner with Rivian in hopes of designing its future software-defined vehicle platform. Or Volvo’s catastrophic software failure with its new Volvo EX90 electric car. These stories confirm the huge — and persistently unfillable — software deficit afflicting many car OEMs. So, where should carmakers go to fix their software problem?

The Ojo-Yoshida Report recently had Chet Babla, senior vice president, strategic marketing at Indie Semiconductor, as the guest in our latest episode podcast of “Chat with Junko and Bola”. Although we didn’t intend to talk with Babla about specific examples like VW and Volvo, our conversation reveals the maelstrom of change hitting the automotive industry.

How a Small MEMS Foundry Crashed the CHIPS Act

By Junko Yoshida

What’s at stake:
The CHIPS and Science Act has created the opportunity — and federal subsidies — for semiconductor companies both big and small to return chip production capacity to the United States. But thus far, the Department of Commerce’s decision-making process has been shrouded in mystery. The latest announcement of Rogue Valley Microdevices getting the grant gives us a glimpse into the federal government’s inner workings.

Likely ingredients necessary to horn into federal funding action? Chutzpah, street cred, and experience in the technology biz.

Without the power of major market share, what does it take to horn into federal funding action?  Likely ingredients include chutzpah, street cred, and experience in the technology biz. These qualities exist emphatically at Rogue Valley Microdevices (Medford, Oregon), a pure-play MEMS foundry founded by Jessica Gomez, once a lab operator at Standard Microsystems (SMSC) in Long Island, New York. Gomez worked at a small aging fab — attached to the then SMSC’s headquarters — where the company made MEMS inkjet printheads. 

Gomez’s journey started with a local community college science degree. She gained first-hand operational experience at SMSC and went on to run a foundry service at a short-lived MEMS company in California. This background convinced Gomez that she could establish her own MEMS foundry. She launched Rogue Valley Microdevices (RVM) in 2003.

VW’s Software Crisis isn’t VW’s Alone

By Junko Yoshida

It’s easy to pick on Volkswagen.

The dizzying array of Volkswagen’s recent partnerships, joint ventures and investments is all over the map – in geography and business focus. Worse, all this churn shows no apparent thread, at least to outsiders like myself, that might help VW to knit the tangle together. 

Paired with VW’s frequent reorganizations and management changes in recent years, such deals beg the conclusion that the organization is in disarray, throwing spaghetti on the wall to see what sticks. Maybe things aren’t that bad. Maybe it just looks bad.

Silicon Shield Gives Way to Silicon Alliance

Can Silicon Alliance Survive What Broke Taiwan’s Silicon Shield?

By Bolaji Ojo

What’s at stake:

Taiwan’s political and business leaders adopted the Silicon Shield as a concept that would protect the island from geopolitical interference. Supply shortages and the renewed interest in localized chip production globally exposed the weakness of the Silicon Shield. Industry executives wary about restrictions on global collaborations are floating the idea of a Silicon Alliance of friendly nations. That concept, too, may fall victim to the landmine of national interests.

Did the global semiconductor industry jump from the frying pan into the fire?

This question is being raised as observers contemplate the expansive involvement of national and regional governments in the semiconductor value chain and the impact on the chip market’s traditional R&D, sales and operating structures.

Global collaboration, a fundamental pillar and growth driver for the semiconductor industry, is seen as coming under threat with governments and regional bodies trying to insulate their supply chains against geo-political threats and other instabilities, including economic dangers arising from uncontrollable shortages.

At industry events, chip executives are expressing reservations about the actions of national governments that they believe have imposed severe restrictions on collaboration activities in the areas of R&D, product exports, other procurement activities, manufacturing, foreign employment, IP and advanced production equipment.

While governments have always been involved in the semiconductor business, observers said they have assumed a more aggressive posture since the end of the Covid-19 pandemic. Somewhere in the rush to insulate their supply chains against shortages and manufacturing instabilities, the world’s leading economies have taken actions and made pronunciations that executives believe threaten to jeopardize the industry’s long-term health.

Can Ceva Ignite Yet-To-Explode TinyML Market?

Can Ceva Ignite Yet-To-Explode TinyML Market?

By Junko Yoshida

What’s at stake:
TinyML in embedded systems can be implemented many ways, often by leveraging beefed-up MCUs, DSPs, AI accelerators and Neural Processing Units (NPUs). The lingering dilemma is how best to develop embedded systems with machine learning that could fit in the budget of TinyML.

Almost every new technology overheats its industry’s imagination, followed by an announcement flood, promising new tools, software and hardware – all of which fuels dreams of rapid market growth and big volume sales.

Then, reality.

TinyML has reached this moment.

Industry Pivots from Self-Driving to Software-Defined

Industry Pivots from Self-Driving to Software-Defined

By Junko Yoshida

What’s at stake:
Eager beavers in the auto industries skipped some fundamental technology and business steps in their rush to bring autonomous vehicles to the market. As they go back to the drawing board, can OEMs redesign an E/E vehicle architecture for SDVs that speeds up automotive innovation? 

There is ample evidence that the heralded rollout of advanced autonomous vehicles has stalled. By any measure, it isn’t “just around the corner.”

Although I hesitate to knock the engineering community’s ambitions to develop vehicle autonomy, I can respectfully suggest that tech suppliers, automakers, thinktanks, politicians, marketers and media come clean on AVs. A collective intellectual dishonesty has blinded us to the reality that autonomous vehicles were never close to being ready for prime time. The result is a pervasive consumer distrust in self-driving cars.
