Abstract：As electronic products become an integral part of daily life, their application in safety-critical automotive systems has become ubiquitous. The International Organization for Standardization (ISO) 26262 standard outlines guidelines for establishing a good safety level in automotive System-on-Chips (SoCs). However, despite adherence to this standard, operational failures may still occur, necessitating Safety Mechanisms (SMs) to … Read more
Abstract—This article introduces a fault injection library for SystemC/SystemC AMS, which can be used to dynamically integrate fault structures into any SystemC/SystemC AMS description. The injection is achieved by dynamically reconnecting the netlist at the start of the test case execution without altering the DUT model itself. This method has been successfully validated on a … Read more
Editor’s Note In the development of electronic control systems for smart vehicles, functional safety verification faces significant challenges: traditional fault injection testing methods are inefficient, lengthy, and costly, and they struggle to comprehensively cover the various abnormal scenarios required by the ISO 26262 standard (such as ASIL D level). As the complexity of automotive electronic … Read more
Note:“Development of Fault Injection Methods and Fault Coverage Analysis for Safety-Critical SoCs” is a series of articles consisting of two parts: “Part 1” and “Part 2”. This is “Part 2”, where we will detail the FIeVC itself and the preparatory phase scripts in Section 2. Section 3 explains the steps to execute a complete fault … Read more
1. Introduction: Why is Chaos Engineering Needed? In the cloud-native era, system complexity is growing exponentially, and traditional testing methods can no longer cover all failure scenarios. Chaos Engineering is a proactive experimental approach that injects faults to help us discover system weaknesses before real failures occur in production environments. As a CNCF incubated project, … Read more
Five years ago, a new adjustable ECU/ECM claimed to be “unhackable” and dominated the market at that time; it was the GM E41 ECM Services (L5P). This ECU/ECM first appeared on the L5 Peter Max truck in 2017, and many believed that such ECUs/ECMs could not be hacked or tuned. As experts from the external … Read more
01 Introduction to Fault Injection Methods In critical scenarios related to functional safety, intensive testing activities are essential to ensure that new systems and built-in fault tolerance mechanisms operate as expected. Ensuring that the system operates normally in the event of a failure (Fail Operational) is a more complex issue than traditional testing content. The … Read more
