Engineering Contradiction Analysis
1Productivity
If manual input methods are used to determine compensation circuit elements, then design flexibility is maintained, but processing time and error rate increase significantly
Solution Approach 1:
The system automatically calculates compensation lengths by extracting measured length parameters from the optical circuit design and comparing them against design length parameters. The EDA system performs self-service by generating compensation circuit elements without requiring manual intervention, thereby reducing processing time while maintaining design flexibility through automated parameter extraction and calculation.
Solution Approach 2:
The patent replaces manual mechanical processes with automated computational processes. Instead of manual calculation and adjustment, the system uses computer processors to automatically determine compensation lengths through mathematical operations on extracted parameters, substituting human manual work with automated electronic computation to reduce errors and time.
2Productivity
If automated calculation is implemented, then processing time is reduced, but system complexity increases
Solution Approach 1:
The system segments the compensation calculation process into distinct functional modules: parameter extraction module, length calculation module, and circuit element generation module. By dividing the complex task into manageable segments, the system achieves automation and improved processing speed while keeping each individual module relatively simple and manageable.
Solution Approach 2:
The EDA system is designed with multi-functionality to handle various aspects of optical circuit design including parameter extraction, length calculation, and circuit element generation within a single integrated platform. This universal approach reduces overall system complexity by consolidating functions rather than requiring separate specialized systems for each task.
3Reliability
If compensation circuit elements are manually determined, then design customization is easier, but timing and phase constraint compliance decreases
Solution Approach 1:
The system implements feedback mechanisms by automatically extracting measured length parameters from the optical circuit design, comparing them against the design length parameters, and using the difference to calculate compensation lengths. This closed-loop feedback ensures that timing and phase constraints are automatically complied with while maintaining ease of operation through automated parameter extraction and calculation.
Solution Approach 2:
The system automatically adjusts waveguide configuration parameters by calculating compensation lengths based on the difference between measured and design length parameters. This automated parameter change ensures constraint compliance while maintaining ease of operation, as the system handles the complexity of parameter adjustment automatically rather than requiring manual intervention.
