Cleared—And Verified—For Takeoff


If you’re like me, you’re probably not in any hurry to get on an airplane amidst our current global pandemic. Commercial air travel has declined dramatically as a result of the novel coronavirus—but beyond private and recreational travel, aviation remains an essential component of many key areas of modern life, including military and defense; commerce and package delivery; medical care; s... » read more

Expanding Automotive Safety With SOTIF


For years, automotive engineering teams have worked to comply with the industry standard ISO 26262, uncovering and addressing functional safety (FuSa) hazards such as software bugs and hardware failures. This standard aims to ensure that complex electronics in today’s cars are reliable ― delivering consistent performance over time, with no critical system failures. With the emergence of ... » read more

Auto Chip Reliability Opens Door To Other Industries


Digital chips in the semiconductor industry evolve from each other. Ideas flow into each other over the years, with occasional big leaps in evolution. The term ‘evolution’ fits because one chip evolves to perfectly optimized for one industry niche. But what happens when one industry’s chip becomes a useful for other industries because it is more cost-effective than what is being used i... » read more

Accellera Tackles Functional Safety


During DAC, Accellera had a workshop about functional safety. In case you don't know, Accellera has a relatively new working group (WG) on Functional Safety. The chair is Cadence's Alessandra Nardi, who coincidentally also received the Marie Pistilli Award for Women in EDA during DAC (you can read more about that in my post Alessandra Nardi Receives Marie Pistilli Award for Women in EDA). But ... » read more

Multiphysics Reliability Signoff For Next-Generation Automotive Electronics Systems


Automotive electronics systems depend on an ever-increasing number of electronic sensors and processing elements, which allow for 360-degree surveillance and object identification/classification. Designing and verifying these systems is, however, as complex as the systems themselves. This white paper examines how automotive chip designers can achieve the stringent safety and reliability requ... » read more

Mitigating The Effects Of Radiation On Advanced Automotive ICs


The safety considerations in an automotive IC application have similarities to what is seen in other safety critical industries, such as the avionics, space, and industrial sectors. ISO 26262 is the state-of-the-art safety standard guiding the safety activities and work products required for electronics deployed in an automotive system. ISO 26262 requires that a design be protected from the eff... » read more

Automotive Gateway IP Enabling Scalable Automotive Platforms


As automakers introduce new electronic platforms, the system architectures are changing from distributed ECUs to integrated domain compute modules. This evolution, along with the increased number and types of sensors for ADAS systems, is having a big impact on the automotive Ethernet network and gateway function. Automotive Ethernet and gateways do more than support mobile connectivity, they en... » read more

How To Meet Functional Safety Requirements With Built-In-Self-Test


With the rapid growth in semiconductor content in today’s vehicles, IC designers need to improve their process of meeting functional safety requirements defined by the ISO 26262 standard. The ISO 26262 standard defines the levels of functional safety, known as Automotive Safety Integrity Level (ASIL), and is a mandatory part of an automotive system design process. The ASIL categories range... » read more

Four Steps To ISO 26262 Safety Mechanism Insertion And Validation


By Ping Yeung, Jin Hou, Vinayak Desai, and Jacob Wiltgen The complexity of automotive integrated circuits (ICs) has grown exponentially with the introduction of advanced driver-assistance systems and autonomous-drive technologies. Directly correlated to this hike in complexity is the increased burden of ensuring an IC is protected from random hardware faults—functional failures that occur ... » read more

CodaCache: Helping to Break the Memory Wall


As artificial intelligence (AI) and autonomous vehicle systems have grown in complexity, system performance needs have begun to conflict with latency and power consumption requirements. This dilemma is forcing semiconductor engineers to re-architect their system-on-chip (SoC) designs to provide more scalable levels of performance, flexibility, efficiency, and integration. From the edge to data ... » read more
