Distributed Development Of IP And SoC In Compliance With Automotive ISO 26262


Automotive functional safety System-on-Chips (SoCs) for Advanced Driver Assistance Systems (ADAS) contain several complex Intellectual Property (IP) cores. The IP cores are developed as a Safety Element out of Context (SEooC), meaning the context of the end application is not fully known at delivery time. In addition, IP development might be distributed across the globe. To reduce the risk of f... » read more

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

Tessent LogicBIST With Observation Scan Technology


Meeting the ISO 26262 requirements for high quality and long-term reliability mans implementing on-chip safety mechanisms with high defect coverage of IC logic. This paper describes Observation Scan Technology, a new new logic built-in-self-test (BIST) technology that improves logic BIST test quality and reduces in-system test time. Empirical results demonstrate 90% test coverage with up to 10X... » 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

Adding Value With Unit Level Traceability (ULT) In Automotive Packaging


Automotive product traceability has existed in one form or another for several decades. Traceability generally refers to tracking and tracing each component that comprises every sub-system in a car. Traditionally, this has been achieved with direct part marking on mechanical or electronic components, using 1D or 2D barcodes or radio-frequency identification (RFID). Since vehicle recalls are cos... » read more

Functional Safety For Fail-Operational Systems


Functional safety issues have long been an important part of product development wherever machine operations that are potentially dangerous for humans are carried out unattended. However, in terms of electrical and electronic systems, the need has been limited to a few industries such as medical technology and aerospace. Apart from that, the functional safety concepts were only used for niche p... » read more

IP Safe Enough To Use In Cars


IP that is used for functional safety needs to respond to events that can happen, whether those are planned or random. Jody Defazio, vice president of IP quality and functional safety at Synopsys, talks with Semiconductor Engineering about ASIL compliance, what the different levels mean, and the impact of using chips developed at the most advanced process nodes in automotive applications. » 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

Learning ISO 26262 – 2nd Edition


You might think that when you get into a debate with a customer or a supplier about the exact interpretation of some aspect of ISO 26262, all you have to do is go to the standard, look it up, and there’s the answer you all need, plain as day. That would be ideal but often doesn’t reflect reality. To realize why, you have to understand the background to the standard. A short ISO 26262 o... » 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
