Engineering Contradiction Analysis
1Adaptability or versatility
If the circuit is large and includes a large number of circuit parameters, then the circuit design can achieve higher functionality and complexity, but the constructed operation matrix becomes complex and the simulation efficiency decreases
Solution Approach 1:
The patent divides a large-scale circuit into multiple sub-circuit modules, each with fewer parameters. By segmenting the circuit, the operation matrix construction complexity is reduced while maintaining the overall circuit functionality. Each sub-circuit can be simulated independently with simpler matrices, improving overall simulation efficiency.
Solution Approach 2:
The patent introduces an intermediary processing step where sub-circuits are first simulated separately to obtain intermediate results, which are then combined to achieve the final circuit simulation. This intermediary approach avoids constructing a single large complex operation matrix while preserving the complete circuit behavior.
2Adaptability or versatility
If the circuit includes a large number of circuit parameters, then the circuit can implement more complex functions, but the operation matrix construction becomes more complex and computational resources increase
Solution Approach 1:
The patent segments the large operation matrix into multiple smaller sub-matrices corresponding to different sub-circuits. Each sub-matrix has fewer rows and columns, reducing construction complexity and computational burden while collectively representing the complete circuit through their interconnections.
Solution Approach 2:
The patent combines results from multiple sub-circuit simulations through defined connection relationships to achieve the overall circuit simulation effect. This merging approach allows complex circuit behavior to be reconstructed from simpler component simulations without requiring a single large operation matrix.
