Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional testers are used to perform cold boot tests, then test reliability is improved, but test cost increases
Solution Approach 1:
The target computer performs self-testing by automatically executing the test program and sending feedback signals during boot operations, eliminating the need for external professional testers while maintaining test reliability through automated error detection and condition retention
Solution Approach 2:
The host computer creates a virtual copy of the tester's functionality by executing test programs and analyzing feedback signals, replicating the professional tester's capabilities through software-based automation rather than requiring physical testing equipment
2Extent of automation
If professional testers are used to perform cold boot tests, then test automation is improved, but device complexity increases
Solution Approach 1:
The host computer serves multiple functions as both the test controller and the analysis system, while the autorun module provides universal error detection capabilities that work across different boot scenarios, reducing the need for specialized testing equipment and simplifying the overall system architecture
Solution Approach 2:
The feedback signal acts as an intermediary mechanism between the target computer's boot state and the host computer's analysis capabilities, enabling automated testing through simple signal exchange rather than complex direct integration, thus maintaining automation while minimizing system complexity
3Productivity
If the target computer is restarted during abnormal booting, then test continuity is improved, but error condition retention is worsened
Solution Approach 1:
The system performs preliminary error detection by monitoring feedback signals during each boot attempt before restart occurs, capturing and retaining error conditions in advance of the restart operation, thus maintaining both test continuity and error information for subsequent analysis
Solution Approach 2:
The feedback signal mechanism provides continuous information about the boot state to the host computer, enabling real-time error detection and condition retention throughout the testing process, allowing the system to maintain productivity by restarting while preserving critical error data for debugging

AI summary
A boot test system applied to test a cold boot in a target computer is provided. The boot test system includes a host computer and an autorun module. The host computer is used to test the target computer to turn power on/off and output a power-on signal and a power-off signal to the target computer based on a feedback signal. The autorun module installed in the target computer is used to output the feedback signal to the host computer during the boot of the target computer. Whereby, the present invention retains a fail result of the boot of the target computer for debugging by a worker.
