Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual evaluation of voltage and timing requirements is performed, then testing accuracy can be maintained, but labor costs and time consumption increase significantly
Solution Approach 1:
The patent creates a digital copy of the test specification in structured file format that contains all voltage requirements, timing requirements, and relative constraints. This digital copy can be automatically processed by computers to generate test sequences, eliminating the need for manual evaluation while maintaining complete accuracy of the testing requirements.
Solution Approach 2:
The patent replaces the manual mechanical evaluation process with an automated computer-based system. The structured file format allows computer programs to automatically parse, process, and generate test sequences based on the stored requirements, substituting human labor with automated digital processing.
2Reliability
If manual consideration of all requirements and constraints is performed, then testing reliability can be maintained, but labor costs increase
Solution Approach 1:
The patent stores all requirements and constraints as a digital copy in structured file format, enabling automated processing that maintains complete reliability while eliminating manual labor. The digital storage preserves all necessary information without loss, allowing computers to reliably process complex test specifications.
Solution Approach 2:
The system enables self-service automation where the structured file format itself contains all necessary instructions for test sequence generation. The computer system automatically reads and processes the stored requirements without needing manual intervention, making the testing process self-sufficient and labor-free.
3Measurement precision
If multiple repetitions of testing procedure are performed to ensure high confidence, then testing accuracy improves, but time consumption and labor costs increase
Solution Approach 1:
The patent stores all testing requirements and constraints as a digital copy that can be automatically processed to generate multiple test sequences. This allows systematic generation of repeated test procedures without manual intervention, maintaining high confidence through multiple repetitions while improving efficiency through automation.
4Measurement precision
If relative constraints between power rail signals are manually considered, then testing accuracy is maintained, but device complexity increases
Solution Approach 1:
The patent stores relative constraints between power rail signals as part of the digital copy in structured file format. This allows computers to automatically process and enforce these constraints during test sequence generation, maintaining testing accuracy while reducing the complexity burden on manual operators.

AI summary
The present disclosure generally relates to a method for generating a signal test specification, a data processing circuit, and a cloud system. The signal test specification is to be applied by a measurement device for testing a device under test. At least one first voltage requirement and at least one first timing requirement for a first power rail signal of the device under test to be tested are stored in a structured file format. At least one second voltage requirement and at least one second timing requirement for a second power rail signal of the device under test to be tested are stored in a structured file format. At least one relative constraint having a relation between at least two of voltage requirements and timing requirements is stored in a structured file format.
