Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current hardware design techniques use logic to address multiple cases, then the ability to handle complex circuit designs is improved, but the difficulty of producing and analyzing the logic increases
Solution Approach 1:
The patent segments the complex logic analysis into multiple hierarchical levels. The verification system divides the circuit design into different abstraction levels, allowing each level to be analyzed separately with appropriate verification techniques. This segmentation reduces the overall complexity by breaking down the monolithic analysis problem into manageable sub-problems that can be solved independently and then integrated.
Solution Approach 2:
The patent introduces a new dimension of analysis by adding temporal and hierarchical dimensions to the verification process. Instead of analyzing all cases simultaneously in a single dimension, the system analyzes circuits across multiple time steps and hierarchical levels, transforming the complexity from a spatial problem into a multi-dimensional problem that can be more efficiently managed and analyzed.
2Measurement precision
If hardware design uses detailed logic for single specific cases, then the precision of verification is improved, but the productivity and efficiency decrease
Solution Approach 1:
The patent implements dynamic verification by allowing the verification system to adapt its precision and depth based on the specific design context, criticality of components, and verification stage. The system dynamically adjusts the level of detail in logic analysis, applying more precise verification only where necessary while using faster, less detailed methods for routine verification, thereby maintaining precision where needed while improving overall productivity.
Solution Approach 2:
The patent applies partial verification actions by selectively verifying only the critical paths and components that have the greatest impact on circuit correctness. Instead of applying exhaustive verification to every single logic element, the system identifies and focuses verification efforts on the most critical cases, achieving sufficient precision for practical purposes while significantly improving design efficiency by avoiding unnecessary verification overhead.
