Unit Re-modification Test Method Using Pattern Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current test methods for software or hardware systems are inefficient in determining the cause of changes in unit modules and ensuring the retention of original functions during modification processes, especially when modifications occur within complex systems, as they primarily rely on observing changes before and after modifications without comprehensive analysis.
Innovation Solution
A test method that generates control and experimental patterns using identical sample patterns to compare changes in function modules, ensuring the original function is retained by inputting these patterns into the system before and after modification, and comparing the results to determine if the original function is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional test methods are used to observe changes before and after modification, then the testing process is simple, but the ability to determine the cause of changes and ensure original function retention is insufficient
Solution Approach 1:
The patent segments the testing process into distinct phases: generating control patterns before modification, performing modification, generating experimental patterns after modification, and comparing the two sets of patterns. This segmentation allows for precise identification of changes while maintaining a structured, manageable testing workflow that addresses both measurement precision and process complexity.
2Reliability
If comprehensive analysis is performed to ensure original function retention, then the accuracy of function verification is improved, but the testing cost and time increase
Solution Approach 1:
The patent applies preliminary action by generating control patterns and establishing baseline measurements before the modification occurs. This pre-prepared reference data enables efficient post-modification comparison, ensuring reliable function verification without requiring extensive re-testing after modification, thus reducing overall testing time while maintaining high reliability.
3Measurement precision
If identical sample patterns are used to generate control and experimental patterns, then the comparison accuracy is improved, but the testing procedure becomes more complex
Solution Approach 1:
The patent employs homogeneity by using identical sample patterns for generating both control patterns (before modification) and experimental patterns (after modification). This consistent input ensures that any differences in output patterns are solely due to the modification itself, not variations in input data, thereby maximizing comparison accuracy. The standardized approach actually simplifies the procedure by eliminating the need to manage different input datasets.

AI summary
The present invention described a test method for unit re-modification, in which there is a test end and a host end. The method generated a sample pattern at a test end, generates a control pattern and modifies a re-modification unit. Otherwise, an experimental pattern is generated and then whether or not the original function is retained after modifying the re-modification unit is determined according to the result of comparison of the control pattern and experimental pattern thereon. The present invention is used to test the internal function module of specific software or hardware, and ensure that the proper function is retained after re-modification.
