Automotive Test Moves In-System


With the electrification of automobiles, it’s not enough to test the new electronics thoroughly at the end of the manufacturing process. Safety standards now require that tests be performed live, in the field, with contingency plans should a test fail. “We see clear demand from the automotive semiconductor supply chain for design functionality specifically aimed at in-system monitoring,... » read more

Automotive Functional Safety Compliance In EDA Tools And IP


By Swami Venkat and Meirav Nitzan A modern vehicle can boast as many as 100 million lines of code—that’s more than the Large Hadron Collider (50 million lines) and Facebook (62 million lines). On the hardware side, many of today’s cars have upwards of 100 electronic control units (ECUs) to run various functions. As automotive engineering ingenuity continues to drive further innovation ... » read more

Change Management With Impact Analysis During Safety-Critical IP And SoC Development


Standards like ISO 26262 provide guidance to mitigate safety risks by defining safety analyses requirements and processes. The standard describes Change Management as a way to analyze and control changes in safety-related work products, items, and elements throughout the safety lifecycle. Impact analysis, a part of the Change Management process, is a systematic approach for evaluating changes t... » read more

Safeguarding Automotive Electronics


Modern automobiles can have up to 100 Electronic Control Units (ECUs) depending on their class, make, and model, with the number of ECUs rising even higher in the case of electric vehicles. An ECU is an embedded system in the car’s electronics. They are used to control all the vehicle's functions, including engine, powertrain, transmission, brakes, suspension, dashboard, entertainment system ... » read more

Dependent Failure Analysis For Safety-Critical IP And SoCs


By Shivakumar Chonnad, Radu Iacob, and Vladimir Litovtchenko Due to the increased complexity in safety-critical system hardware, software, and mechatronics, the functional safety development process must address systematic and random hardware failures. Numerous safety-related activities are performed during safety-critical IP and SoC developments, as part of the safety lifecycle, from produc... » read more

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
