Embedded systems are a crucial part of our daily lives, from the coffee machine that starts our day to the security system that protects our homes at night. These systems are designed to perform specific tasks and are often integrated into larger systems to provide a seamless user experience.

With so many applications relying on embedded systems, it is essential to ensure they are reliable and perform their intended tasks without failure. This blog post will provide tips and guidance on creating a reliable embedded system.

Understanding the Requirements

Before beginning the design and development of an embedded system, it is important to understand its requirements and constraints.

Identify the System Requirements

It is essential to identify the requirements to ensure that the embedded system meets the user’s needs. This includes defining the system’s purpose, tasks, and desired outcome. It is also essential to consider the user’s preferences, such as size, power consumption, and ease of use.

Define the Constraints and Trade-Offs

Once the system requirements have been identified, the next step is to define the constraints and trade-offs that must be considered during the development process. For example, there may be regulations on the system’s size, power consumption, or cost. It is essential to balance these constraints and trade-offs to create a system that meets the requirements and is feasible to develop and implement.

Evaluate the Feasibility of the Requirements

Finally, it is important to evaluate the feasibility of the requirements. This involves determining whether the system can be developed and implemented within the given constraints and trade-offs. If the requirements are infeasible, they may need to be revised or changed to ensure that the system is both reliable and practical to develop.

Selecting the Right Hardware

Choosing the right hardware is critical in creating a reliable embedded system.

Choose the Appropriate Microcontroller

The microcontroller is the heart of the embedded system, and choosing the right one is essential. When selecting a microcontroller, consider the system’s requirements, such as processing power, memory, and input/output (I/O) capabilities.

Consider Memory and Storage Requirements

Memory and storage requirements should also be considered when selecting the hardware for an embedded system. Depending on the system’s requirements, you may need to choose between flash memory and RAM or a combination of both.

Evaluate the Suitability of Other Components

In addition to the microcontroller and memory, other components, such as sensors, actuators, and communication interfaces, may also need to be considered when selecting the hardware for an embedded system. It is essential to evaluate the suitability of each component based on its performance, reliability, and cost.

Writing Reliable Software

Writing reliable software is critical to the success of an embedded system.

Write Efficient and Error-Free Code

The first step in writing reliable software is to write efficient and error-free code. This involves using best practices to ensure that the code is well-structured and free of bugs. In addition, make sure to follow embedded security testing best practices like those from Code Intelligence to avoid any pitfalls.

Implement Robust Error Handling Techniques

Implementing robust error-handling techniques, such as error logging and recovery, is also essential to ensure that the system continues to operate even if an error occurs. 

Verify and Validate the Software

Finally, verifying and validating the software is important to guarantee that it satisfies the conditions and procedures as planned. This may involve conducting manual and automated testing to identify bugs or other issues.

Testing the System

Testing is a vital phase in the evolution of a dedicated embedded system.

Conduct System Tests

System tests should be conducted to ensure that the entire system meets the requirements and functions as expected. This may involve testing each component individually or conducting more complex tests with multiple components operating together.

Test for Reliability and Performance

In addition to system testing, it is also important to test for reliability and performance. This may include stress testing, temperature cycling, and environmental testing, among other types of tests.

Record Test Results and analyse Data

Finally, it is essential to document all test results and analyse them to identify any issues or areas of improvement. These details can then be utilised to refine the system design in order to increase its reliability.

Ensuring Quality Assurance During the Development Process

It is also crucial to ensure quality assurance during the development process. This involves implementing processes and procedures to ensure that each step of the development process is completed correctly and with the necessary level of quality. Quality assurance can be achieved through code reviews, regular testing, and other activities that verify that the system meets its requirements.


Embedded systems are becoming increasingly complex, and developers need to take the necessary steps to ensure that these systems are reliable. With the steps discussed in this guide, developers can create embedded systems that will last for many years of use. Best of luck!
