Formal Verification Becoming Critical To Auto Security, Safety


Formal verification is poised to take on an increasingly significant role in automotive security, building upon its already widespread use in safety-critical applications. Formal has been essential component of automotive semiconductor verification for some time. Even before the advent of ADAS and semi-autonomous vehicles — and functional safety specifications like ISO 26262 and cybersecur... » 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

Sensing Automotive IC Failures


The sooner you detect a failure in any electronic system, the sooner you can act. Together, data analytics and on-chip sensors are poised to boost quality in auto chips and add a growing level of predictive maintenance for vehicles. The ballooning number of chips cars makes it difficult to reach 10 defective parts per billion for every IC that goes into a car.  And requiring that for a 15-y... » read more

Automotive Chip Design Workflow


Stewart Williams, senior technical marketing manager at Synopsys, talks about the consolidation of chips in a vehicle and the impact of 7/5nm on automotive SoC design, how to trade off power, performance, area and reliability, and how ISO 26262 impacts those variables. » read more

Aligning Automotive Safety Requirements Between IP And SoCs


Today’s SoCs for automotive safety-related systems integrate numerous IP blocks. At the system level, the Hardware Software Interface (HSI) between these IP blocks needs to be verified in simulation and validated in prototype. However, the scaling of the scope and effort to verify or validate is not linear based on the growing complexity of SoCs and their components such as IP. Depending on t... » read more

Ensuring Functional Safety For Self-Driving Cars


There may be no hotter topic in electronics than chips for autonomous vehicles. Self-driving cars have captured the public imagination and become a major area of investment. Both established automotive manufacturers and well-funded startups are producing vehicles with the highly complex chips needed to negotiate roads, deal with unpredictable humans and communicate with the cloud for machine le... » read more

Planning For Failures In Automotive


The automotive industry is undergoing some fundamental shifts as it backs away from the traditional siloed approach to one of graceful failure, slowing the evolution to fully autonomy and rethinking how to achieve its goals for a reasonable cost. For traditional automakers, this means borrowing some proven strategies from the electronics world rather than trying to evolve traditional automot... » read more

Functional Safety Implementation Goes Mainstream


Electronics engineers are being thrust into the automotive market like never before. The move to electrify automobiles, along with the advent of self-driving cars, means that silicon designers will be designing ever more sophisticated automotive ICs. But cars aren’t like most other electronic systems; it’s imperative that they cause no harm should they fail. This brings us to the realm o... » read more

Is Your Functional Safety An Afterthought?


Imagine the air bag in your car not inflating during a collision or deploying without a crash during driving! These are two of the failure modes associated with the air bag in your car, none of which you as a driver have any control over. The severity of both these failures is of course very high, but which one would you rate as a higher hazard? The probability of getting into an accident is lo... » read more
