All Security Issues Are Safety Issues


Last month I spoke at the IQPC Safety and Security week event in Munich. It became clear to me that our semiconductor community is really paying attention to these issues now, not just to comply with standards, and not just because of the potential liability – but because it simply makes good business sense. The cost of recalling a single vehicle is estimated to be between $400 and $900 ... » read more

Safety-Critical Coverage


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

Optimization Challenges For Safety And Security


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

Auto Reliability At The System Level


Carmakers and chipmakers are approaching autonomous vehicle design from very different perspectives, and while they both talk about safety and reliability as the end goals, they have widely divergent ideas about how to get there. All of this is just beginning to come into focus as carmakers vie for leadership in the autonomous vehicle space, and much of it appears to hinge on the definition ... » read more

Mostly Upbeat Outlook For Chips


2019 has started with cautious optimism for the semiconductor industry, despite dark clouds that dot the horizon. Market segments such as cryptocurrencies and virtual reality are not living up to expectations, the market for smart phones appears to be saturated, and DRAM prices are dropping, leading to cut-backs in capital expenditures. EDA companies are talking about sales to China being pu... » read more

Bare Metal Programming


As the need for safety and security grows across application areas such as automotive, industrial, and in the cloud, the semiconductor industry is searching for the best ways to protect these systems. The big question is whether it is better to build security and safety into hardware, into software, or both. The answer isn't entirely clear yet, but one of the options under consideration is s... » read more

Adding Safety Into Automotive Design


The ISO 26262 spec is a household term for anyone even remotely involved with the automotive industry today. Increasingly, though, it is being used interchangeably with safety-readiness across the entire supply chain. ISO 26262 compliance is a prerequisite for IP and chips used in an increasing number of automotive applications. It applies to systems, software, and to individual products. An... » read more

The Revenge Of The Digital Twins


How do we verify artificial intelligence? Even before “smart digital twins” get as advanced as shown in science fiction shows, making sure they are “on our side” and don’t “go rogue” will become a true verification problem. There are some immediate tasks the industry is working on—like functional safety and security—but new verification challenges loom on the horizon. As in pr... » read more

How Vehicle Electrification Impacts Electrical System Design


Autonomy and electrification are demanding significant changes to electrical and electronic architectures within vehicles. This is due in part to the introduction of high voltages, increased safety considerations and significant weight reductions needed to maximize vehicle range from electrification, and ‘fail operational’ designs, hugely increased data network loading and virtual validatio... » read more

Safety, Security And PPA Tradeoffs


Safety and security are emerging as key design tradeoffs as chips are added into safety-critical markets, adding even more complexity into an already complicated optimization process. In the early days of semiconductor design, performance and area were traded off against each other. Then power became important, and the main tradeoffs became power, performance and area (PPA). But as chips inc... » read more
