Analysis of the core terminology system
2.1 Basic concepts
Define the three basic characteristics of testability design:
- Controllability (2.1.16): Design characteristic of signal control capability
- Observability (2.1.17): Design characteristic of signal monitoring capability
- Inherent testability (2.1.15): Design attribute independent of test data
2.3 Testing and diagnostic techniques
| Test Types | Definition Points | Typical Applications |
|---|---|---|
| Boundary Scan Test (2.3.1.27) | Board-Level Test Through Chip Internal Structure | High-Density Integrated Circuit Detection |
| Parallel Test (2.3.1.25) | Simultaneous Execution of Multiple Test Tasks | Multi-UUT Batch Test Scenarios |
Implementation Recommendations
- Transition from Old to New Standards: Key Updates New terms such as fault prediction (2.1.21), PHM (2.1.25)
- Design for testability: Integrate test elements in accordance with the comprehensive diagnosis (2.1.13) principle
- Verification method: Use fault injection (2.6.10) technology to verify diagnostic capabilities
