Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual routing is used for metal layer circuit layout, then routing can be completed with existing tools, but time consumption and effort are excessively high
Solution Approach 1:
The system performs self-service by automatically identifying anchor points, determining their relationships, and generating routing plans without requiring manual intervention from layout engineers. The computer executes algorithms that autonomously complete the entire routing process for metal layers, transforming a manually-intensive task into an automated self-service system.
Solution Approach 2:
The patent replaces the mechanical manual routing process with an automated computer-based system. Instead of layout engineers manually creating routing plans, a computer executes automated algorithms that identify anchor points, determine their spatial relationships, and generate optimized routing configurations, substituting human mechanical operations with automated computational processes.
2Adaptability or versatility
If manual routing is used for metal layer circuit layout, then routing can be adapted to design changes, but the process requires high effort and cannot be reused
Solution Approach 1:
The system performs preliminary action by automatically generating routing plans that can be stored and reused for future design iterations. Instead of manually recreating routing plans each time, the automated system pre-generates optimized routes that can be quickly adapted to design changes, enabling reuse and improving overall productivity across multiple design cycles.
3Productivity
If automatic routing is implemented for metal layer, then productivity increases, but unique metal layer rules make automation difficult
Solution Approach 1:
The patent applies segmentation by breaking down the complex metal layer routing problem into distinct manageable components: identifying anchor points, determining their spatial relationships, classifying them by supply net, and generating routing plans for each group. This segmentation of the routing process into discrete steps makes automation feasible despite the complexity of metal layer rules.
Solution Approach 2:
The system handles parameter changes by dynamically adjusting routing parameters based on the identified anchor points and their relationships. The automated system modifies routing configurations according to the specific parameters of each metal layer design, enabling adaptation to unique rules while maintaining high productivity through systematic parameter management.
