Engineering Contradiction Analysis
1Reliability
If manual simulation and verification methods are used for semiconductor package design, then design verification can be performed, but significant manual effort and time are required
Solution Approach 1:
The patent replaces manual mechanical processes with automated computational systems. Specifically, it substitutes manual netlist generation and simulation verification with an automated system that uses graph theory algorithms and computer-based simulation tools to perform the same verification functions, thereby reducing manual effort and time while maintaining verification reliability
Solution Approach 2:
The system enables self-service automation where the semiconductor package design system automatically generates netlists, performs simulations, and conducts verification without requiring manual intervention at each step. The automated workflow manages the entire design verification process independently, reducing dependency on manual operations
2Productivity
If automated netlist generation is implemented, then design efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces graph theory as an intermediary mathematical framework that bridges the connection information of semiconductor components and the netlist generation process. By representing components as vertices and connections as edges in a graph structure, the system automates netlist generation through systematic graph processing algorithms, improving efficiency while managing complexity through a structured intermediate representation
Solution Approach 2:
The system transforms physical connection information into graph-theoretic parameters (vertices, edges, adjacency matrices) and then converts these into netlist parameters automatically. This parameter transformation approach enables automated netlist generation by changing the representation form of design data, thereby improving productivity while containing system complexity through standardized transformation rules
