7. System Integration Principles in Hardware Engineering
System integration involves the seamless combination of hardware and software components to create an effective, cohesive system. Key aspects of this process include validating individual modules, conducting rigorous testing at various levels, and identifying and solving potential issues early through clear interface definitions and incremental assembly. Effective integration methodologies can significantly enhance system reliability and performance.

What we have learnt
- System integration is essential for ensuring that all hardware and software components function together as a unified system.
- The integration process includes validating components, testing interfaces, and performing system-level evaluations to detect issues.
- Best practices involve early integration, comprehensive documentation, and adherence to testing protocols.
Key Concepts
- -- Subsystem
- An individual module with a defined function, such as a sensor, power supply, or communication module.
- -- Interface
- The electrical, mechanical, or logical connection between modules that enables communication and functionality.
- -- Integration Point
- A stage in the integration process where different components are combined to form a complete system.
- -- Incremental Integration
- The gradual assembly and testing of subsystems that allows for early identification and resolution of issues.
- -- Integration Testing
- A testing process aimed at ensuring all components of the system operate together as intended, including various types of tests such as smoke tests and regression tests.
