1 Component selection

One of the first steps to ensure Arm hardware reliability is to choose the right components for your project, such as the processor, memory, storage, sensors, and peripherals. You should consider factors such as the power consumption, performance, compatibility, availability, and cost of each component, as well as the environmental conditions and requirements of your target application. You should also evaluate the quality and reliability of the component vendors, and check their datasheets, specifications, and warranties carefully.

Absolutely, as a computer expert, here's a detailed breakdown of ensuring Arm hardware reliability through component selection, architecture design, and software development: 1. Component selection: Critical Components: Choosing reliable components is akin to selecting the building blocks of a sturdy structure. For Arm hardware, this involves meticulous scrutiny of processors, memory modules, storage drives, and other key components. Opting for established manufacturers known for quality assurance and reliability is crucial. Compatibility and Integration: Ensuring compatibility and seamless integration between different components is vital.

2 Architecture design

Another important step to ensure Arm hardware reliability is to design a robust and efficient architecture for your system, such as the circuit board, the power supply, the communication interfaces, and the security features. You should follow the best practices and guidelines for Arm hardware design, such as using proper grounding, shielding, routing, and soldering techniques, avoiding electromagnetic interference and noise, and implementing protection mechanisms against overvoltage, overcurrent, and short circuits. You should also use simulation and verification tools to validate your design and identify potential errors or issues.

2. Architecture design: Robust Architecture: Designing a reliable architecture requires a thorough understanding of system requirements and potential failure points. Employing fault-tolerant designs, redundancy measures, and scalability considerations within the Arm hardware architecture enhances its resilience. Efficiency and Performance: Balancing reliability with performance is key. Designing an architecture that not only focuses on reliability but also optimizes efficiency without compromising on performance is a hallmark of expert-level design.

While all hardware components play a crucial role, the power supply and PCB design are, in my experience, the foundation for overall device robustness. Regardless of the processor brand (ARM, Microchip, Intel, etc.), a poorly designed power supply or an EMC-susceptible PCB can significantly compromise product reliability.

3 Software development

A third crucial step to ensure Arm hardware reliability is to develop high-quality software for your system, such as the firmware, the operating system, the drivers, and the applications. You should use the appropriate software development tools and environments for your Arm hardware, such as compilers, debuggers, emulators, and IDEs, that support the specific features and functionalities of your processor and components. You should also follow the best practices and standards for software development, such as using modular and reusable code, documenting and commenting your code, and testing and debugging your code thoroughly.

3. Software development: Optimized Software Stack: Tailoring the software stack for Arm hardware involves optimizing code, developing robust drivers, and ensuring firmware compatibility. Expert software development includes creating efficient algorithms and leveraging hardware-specific features to maximize reliability and performance. Testing and Validation: Rigorous testing during software development is pivotal. This includes comprehensive testing of drivers, firmware, and system-level software to detect and rectify compatibility issues, bugs, and potential vulnerabilities specific to Arm hardware. From an expert perspective, meticulous attention to detail in component selection, an architectural design

4 Debugging and testing

A fourth essential step to ensure Arm hardware reliability is to debug and test your system extensively, both during and after the development stage. You should use the proper debugging and testing tools and methods for your Arm hardware, such as logic analyzers, oscilloscopes, multimeters, and probes, that allow you to monitor and measure the behavior and performance of your system and its components. You should also perform various types of testing, such as functional testing, stress testing, reliability testing, and compatibility testing, to verify that your system meets the specifications and expectations of your target application.

Unfortunately, this step completely irrelateve to reliability. Even opposite: certification steps decreases it. The reason is price. Certification has two properties: 1. it doesn't guarantie anything 2. it's not free. Therefore, a company must spend money which affects cost of development. Saveings on development makes all the previous steps worse. It's not related in cases, if a certification company takes all responsibility about cases when an effect declared by certificate (security, safety, reliability) has not been reached. But for now I don't know such cases.
