Semiconductor Engineering: Using AI Data For Security

 Arteris IP's Kurt Shuler, Vice President of Marketing, comments about the edge emerging as a particular security concern because some of the devices can kill you, covered in this Semiconductor Engineering article;

Using AI Data For Security

February 20th, 2019 - By Ann Steffora Mutschler

Pushing data processing to the edge has opened up new security risks, and lots of new opportunities. 

The edge and beyond
“It’s cars and robots and medical devices,” said Kurt Shuler, vice president of marketing at Arteris IP. “These things can kill you two ways. A cosmic ray can cause a bit to flip, and things go awry. The other way is that the AI may work as intended, but what it decides to do from its neural net application is the wrong thing. In that case, the safety of the intended function is bad.”

There’s even a new spec just for this: “ISO/PAS 21448:2019 Road vehicles — Safety of the intended functionality.” That captures how to analyze these AI powered systems going into cars, so they works as designed.

Security can impact all of these systems. “There’s a totally separate set of specs, and a totally separate set of Ph.D. geeks working on safety and on security,” said Shuler. “What’s disconcerting is that the effects of any of these things, especially from a functional safety standpoint and a security standpoint, can be the same. Whether a bit flips or an engineer flipped a bit, someone can get hurt. Yet these sets of experts don’t really talk to each other too much. This was addressed in the new ISO 26262 2018 specification that came out in December, which includes specific text to address this. It basically says you must coordinate with security guys, but unless security is somehow mandated to a certain level — like functional safety is in cars and trains and other verticals — nobody really cares. It’s like insurance. Nobody wants to pay for too much security.”

Semiconductor Engineering: The Race To Multi-Domain SoCs

 Arteris IP's CEO looks at how automotive and AI are Altering chip design in this article in Semiconductor Engineering;

The Race To Multi-Domain SoCs

February 7th,  2019 - By Ed Sperling

K. Charles Janac, president and CEO of Arteris IP, sat
down with Semiconductor Engineering to discuss the impact of automotive and AI on chip design. What follows are excerpts of that conversation.

SE: What do you see as the biggest changes over the next 12 to 24 months?
Janac: There are segments of the semiconductor market that are shrinking, such as DTV and simple IoT. Others are going through an investment phase, including automotive, AI/machine learning and China. You really want to be focused on those segments. 

SE: So does IP that’s being developed today look radically different than it did five years ago?
Janac:
Yes, everything is getting amazingly complex. What people are building right now are multi-domain SoCs. The CPU, which used to do all the work, does relatively less work. There are accelerators for vision and data analysis outside of the CPU subsystem. There are machine learning sections, some general-purpose, some very specific, all on-chip. There is a memory subsystem with very high-bandwidth memory and low latency. There also is functional safety. You need tremendous performance because a car is a supercomputer on wheels. The car has to be very efficient, because you need to deliver that compute power without water cooling. Power management becomes very sophisticated. And then there are functional safety and security subsystems to keep these safe from environmental and man-made issues.

SE: Where does the network on chip (NoC) fit into all of this?
Janac: All data goes through the NoC of the chip. There are opportunities for generating value from that. But the increase in complexity is increasing the number and sophistication of the interconnect parts of the chip. Before, you may have had networks on chip. Now you may have 20 or 30.

Semiconductor Engineering: ISO 26262:2018, 2nd Edition: What Changes?

 Arteris IP's Kurt Shuler, vice president of marketing, delivers a recent update for the ISO 26262 standard in this blog in Semiconductor Engineering;

ISO 26262:2018, 2nd Edition: What changes?

February 7th,  2019 - By Kurt Shuler

The safety standard is now clearer for IP-based designs and those happening across multiple companies.

If you’re involved somehow in design for automotive electronics, you probably have more than a cursory understanding of the ISO 26262 standard. What your organization is working from is most likely the 2011 definition. The most recent update is formally known as ISO 26262:2018, less formally as ISO 26262 2nd Edition.

Standards should evolve, but what changed and why? I’ve been a member of the ISO 26262 working group for many years, and particularly involved in how it should be interpreted for IP, and I’ve got to tell you, I have struggled. 

From my perspective, it was originally written around an implicit expectation that chips are built from scratch entirely within one organization, and this is a dated assumption. There was also not enough guidance for IP-based design or design distributed across multiple companies or sites. The workaround for an IP supplier has been to use the Safety Element out of Context (SEooC) mechanism. But this depends heavily on human interpretation, by the component vendor on what may be relevant to the integrator and vice-versa, with little guidance from the 2011 version of the standard. I complained (whined?) quite a bit to the committee about these problems and they eventually invited me to the working group. I wasn’t the only one confused and other people joined, and we seem to have had an impact; our efforts have resulted in a lot more clarification, organization and practical examples in the latest standard. I think the new Part 11 of the updated standard provides a lot more detail and useful examples for us in the semiconductor and semiconductor IP industry.

Semiconductor Engineering: Chasing Reliability In Automotive Electronics

 Arteris IP's Kurt Shuler, vice president of marketing has authored a paper about ISO 26262 and comments in this article;

Chasing Reliability In Automotive Electronics 

January 15th,  2019 - By Susan Rambo and Ed Sperling

Supply chain changes, resistance to sharing data and technology unknowns add up to continued uncertainty.

"Traditional semiconductor vendors who are making or designing chips to enable autonomous driving applications are nowadays sometimes competing with Tier-1 electronics system designers and OEMs, who may be making their own chips or providing explicit requirements to their semiconductor vendor partners. Additionally, new entrants like Uber, Way and Apple are designing their own complete systems, despite their relative lack of experience in the automotive industry. ISO 26262 mandates high levels of collaboration and information sharing throughout the value chain that may be unfamiliar to new entrants."

The ISO 26262 standard is snapshot of issues and the lengths the whole supply chain has to go. Collaboration is key. Communication is part of the safety standards up and down the automotive safety critical supply chain now. It’s built into the standards.

Sharing knowledge of a supplier’s crown jewels—intellectual property—has to happen among suppliers and auto OEMs. “Participants in the semiconductor and software supply chains are usually secretive about how their IP was developed and how it works in detail,” said Shuler. Suppliers should remember that the “your customer still has an obligation to confirm your compliance with ISO 26262.”
