1. Introduction The previously made test circuit board for the STM32F373 did not have the 16-bit high-precision ADC pins exposed, so a new board was made to test the performance of the 16-bit ADC in the F373. 2. Designing the Circuit Board Based on the previous experimental circuit board, the original output pin header was … Read more
Discussion on Three Issues in Functional Safety of Embedded Systems Three Issues in Functional Safety of Embedded System Functional safety is the basic requirement of modern industrial products. This paper discusses three related topics: The first is that the functional safety demand of automobile is probably higher than that of airplane. This point may affect … Read more

What is Fault Injection Testing? Fault Injection Testing (FIT) is a method where testers deliberately introduce errors into a system to evaluate its robustness and error handling capabilities. This technique simulates faults to observe how the system behaves under unexpected conditions, ensuring that it can gracefully handle failures and recover from them. To execute FIT, … Read more
This article is sourced from: Automotive Electronics and Software (ID: aestech) Introduction to Fault Injection Methods In key scenarios related to functional safety, intensive testing activities are crucial 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) … Read more
Future丨Intelligence丨Nutrition丨Energy Let reading become a habit, let the soul have warmth An Overview of Fault Injection 1. Introduction to Fault Injection In the field of computer science, Fault Injection is a controlled method of injecting faults into computer systems to simulate their responses under real fault conditions. It is widely used in software testing, fault … Read more
In the previous issue, we introduced common software quality measurement models (McCall, Boehm, ISO 9126 models). These models can be used to scientifically evaluate software quality. This issue mainly introduces 7 software quality evaluation indicators (coding standards, source lines of code, bug rate per thousand lines of code, cyclomatic complexity, code coverage, fan-in/fan-out counts, design … Read more
Follow+Star Public Number, don’t miss out on exciting content Source | Embedded Miscellaneous Today we will introduce the design of testable software in embedded systems. What is testability? It means that after you write the software module/function interface, you can conveniently and comprehensively perform self-testing. Let’s look at a simple example to understand testable software. … Read more
