Development process
The development process for embedded software systems is often iterative, meaning that it involves multiple cycles of design, implementation, testing, and refinement. This iterative approach is necessary because embedded software systems are complex and must meet stringent requirements for reliability, safety, and performance.
During the design phase, engineers create a high-level specification of the system’s requirements and architecture. This specification is then used to develop a detailed implementation plan. Once the implementation is complete, the system is tested to ensure that it meets the requirements. If the system does not meet the requirements, the design and implementation are revised and the process is repeated.
The iterative development process allows engineers to identify and correct errors early in the development cycle. This can save time and money in the long run, as it is much more difficult to fix errors once the system has been deployed.
