Engineering Contradiction Analysis
1Loss of time
If fine partitioning is used to increase optimization speed, then runtime decreases, but global information is lost and optimization effectiveness is reduced
Solution Approach 1:
The logic circuit is divided into multiple partitions that can be processed in parallel. Each partition maintains sufficient granularity to preserve global information while enabling independent optimization. The partitioning strategy balances the trade-off by ensuring each partition is small enough for fast processing yet large enough to contain meaningful global structure.
Solution Approach 2:
The patent introduces a hierarchical optimization approach that operates at multiple levels (coarse-grained and fine-grained partitions). This dimensional change allows the system to simultaneously achieve fast processing through fine partitions while maintaining global information through coarse partition views, resolving the contradiction between speed and information preservation.
2Reliability
If coarse partitioning is used to optimize logic circuit effectiveness, then optimization quality improves, but computational complexity increases exponentially
Solution Approach 1:
The optimization problem is segmented into multiple independent partition optimization problems. Each partition can be optimized using appropriate methods without requiring exponential complexity over the entire circuit. The segmentation allows linear or polynomial complexity per partition while maintaining overall effectiveness.
Solution Approach 2:
Instead of optimizing the entire circuit at once (excessive action), the system applies partial optimization to each partition. This partial action approach reduces computational complexity while still achieving effective optimization through the collective improvement of all partitions.
3Productivity
If traditional optimization methods are used, then optimization can be performed, but methods get stuck at local optima and scalability is limited
Solution Approach 1:
By segmenting the circuit into partitions, the optimization method can independently explore different regions of the design space within each partition. This segmentation prevents getting stuck at local optima by allowing parallel exploration across multiple partitions, thereby improving scalability and adaptability.
Solution Approach 2:
The patent employs dynamic optimization strategies that adapt to the structure of each partition. The optimization methods can dynamically adjust their behavior based on the specific characteristics of each partition, enabling better exploration of the design space and avoiding local optima while maintaining scalability.

Approaches include transduction by insertion, transduction by extension, transduction by insertion and extension, redundancy addition, transduction by generalized node insertion, randomized transduction, error correction via transduction, top-down circuit construction, and dynamic optimization scheduling. Various transduction approaches can be completely decoupled from other operations, such that there is no need to modify code when using existing optimizations.
