Safety-Critical Coverage
By Ed Sperling - 24 Apr, 2019 - Comments: 0

Dave Landoll, solutions architect at OneSpin Solutions, discusses verification in safety-critical designs, why it’s more of a challenge in automotive than in avionics, and why verification of these systems includes what the system should not be doing as well as what it should be doing. https://youtu.be/Ze3WwEARfx0 » read more

Blog Review: April 17
By Jesse Allen - 17 Apr, 2019 - Comments: 0

In a video, Mentor's Colin Walls digs into power management in embedded software with a particular look at the Power Pyramid model. Synopsys' Taylor Armerding checks out the state of application security at this year's RSA and finds that while organizations are paying attention to security through training and dedicated teams, roadblocks still remain. Cadence's Paul McLellan considers how... » read more

Optimization Challenges For Safety And Security
By Brian Bailey - 11 Apr, 2019 - Comments: 0

Complexity challenges long-held assumptions. In the past, the semiconductor industry thought it understood performance/area tradeoffs, but over time it became clear this is not so simple. Measuring performance is no longer an absolute. Power has many dimensions including peak, average, total energy and heat, and power and function are tied together. Design teams are now dealing with the impl... » read more

Taking Security-By-Design To The Next Level
By Paul Williamson - 11 Apr, 2019 - Comments: 0

It’s hard to argue that the pre-eminent challenge before our industry today is security. While each sensational hacking headline gets readers’ attention, countless engineers and developers behind the scenes innovate security solutions every day to stay one step ahead of the hackers. At a high level, companies have begun to work together toward holistic solutions to complement their own s... » read more

New Approaches To Security
By Ed Sperling - 09 Apr, 2019 - Comments: 0

Different approaches are emerging to identify suspicious behavior and shut down potential breaches before they have a chance to do serious damage. This is becoming particularly important in markets where safety is an issue, and in AI and edge devices where the rapid movement of data is essential. These methods are a significant departure from the traditional way of securing devices through l... » read more

The Long And Detailed Road To Automotive Compliance
By Ann Mutschler - 04 Apr, 2019 - Comments: 0

Compliance with automotive safety requirements is slowing down both innovation and participation by a flurry of startups as the whole ecosystem struggles to bring autonomous vehicles to reality. This is particularly onerous for chipmakers, which face a high bar for IC integrity and reliability. They must meet specifications and be free of design errors. Improper behavior in corner-case s... » read more

The Blockchain – Not As Secure As You Think
By Rambus - 03 Apr, 2019 - Comments: 0

The blockchain has the potential to touch all aspects of our everyday lives, from buying and trading cryptocurrency, to securing vital healthcare records, to proving that a tomato really is organic. The security challenges, specifically the vulnerability of private keys faced by the cryptocurrency market, prove that before the transformative impact of blockchain technology can be realized, a co... » read more

Heterogeneous Design Creating Havoc With Firmware Versions
By Ed Sperling - 01 Apr, 2019 - Comments: 0

Adding different kinds of processing elements into chips is creating system-level incompatibilities because of sometimes necessary, but usually uncoordinated, firmware updates from multiple vendors. In the past, firmware typically was synchronized with other firmware and the chip was verified and debugged. But this becomes much more difficult when multiple heterogeneous processing elements a... » read more

The Next Spoiler Alert
By Ed Sperling - 07 Mar, 2019 - Comments: 0

Speculative execution seemed like a good idea at the time. As the power/performance benefits of each node shrink began to dwindle, companies like Intel figured out ways to maintain processor speeds at the same or lower power. There were other approaches, as well. Speculative execution and branch prediction are roughly equivalent to pre-fetch in search, which has gotten so good that often the... » read more

Next Wave Of Security For IIoT
By Kevin Fogarty and Ed Sperling - 07 Mar, 2019 - Comments: 0

A rush of new products and services promise to make the famously un-secured Industrial IoT (IIoT) substantially more secure in the near future. Although the semiconductor industry has been churning out a variety of security-related products and concepts, ranging from root of trust approaches to crypto processors and physically unclonable functions, most IIoT operations have been slow to adop... » read more
