Engineering Contradiction Analysis
1Reliability
If the circuit graph includes all optional instances and transistors, then the circuit structure is complete and accurate, but the database becomes complex and search becomes resource-intensive
Solution Approach 1:
The patent extracts and removes optional instances from the circuit graph generation process. By using a netlist that excludes optional instances, the system creates a simplified circuit graph that maintains essential circuit functionality while eliminating unnecessary complexity. This extraction principle directly reduces database complexity while preserving reliable circuit structure representation.
Solution Approach 2:
The patent segments the circuit analysis into distinct phases: netlist generation (excluding optional instances), circuit graph generation (from simplified netlist), and search operations. This segmentation allows the system to handle complexity in manageable portions, creating a simplified representation for search while maintaining completeness through the structured approach.
2Measurement precision
If the circuit graph includes all transistors, then the circuit representation is accurate, but the search speed decreases and resources increase
Solution Approach 1:
The patent extracts optional transistors from the circuit representation. By generating a netlist that excludes optional instances and using this simplified netlist to create the circuit graph, the system maintains accurate representation of essential circuit functionality while removing unnecessary transistor elements that would slow down search operations and increase resource consumption.
Solution Approach 2:
The patent changes the parameter of circuit graph complexity by filtering out optional instances during netlist generation. This parameter change transforms the circuit representation from a complete but complex structure to a simplified structure that maintains accuracy for search purposes while significantly improving search speed and reducing resource requirements.
3Adaptability or versatility
If optional instances are included in the circuit graph, then the circuit functionality is complete, but the graph structure becomes complex and harder to process
Solution Approach 1:
The patent extracts optional instances from the circuit graph generation process by using a netlist that excludes these instances. The circuit graph is generated from this simplified netlist, resulting in a graph structure that maintains essential circuit functionality while eliminating the complexity introduced by optional instances. This extraction preserves adaptability for core circuit operations while simplifying the graph structure for processing.
