Embedded Linux: Asynchronous I/O

In embedded Linux, Asynchronous I/O (AIO) is a powerful I/O model that allows processes to continue executing other tasks while waiting for I/O operations to complete. Compared to I/O multiplexing mechanisms (such as select and poll), asynchronous I/O uses a signal notification mechanism, allowing processes to avoid repeatedly polling the I/O status. Instead, the kernel … Read more

Development of Fault Injection Methods and Fault Coverage Analysis for Safety-Critical SoCs (Part 1)

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

Dynamic Fault Injection Library Method for SystemC AMS

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
