Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If matrix conversion and calculation are used for circuit simulation in EDA software, then the simulation can be performed on complex circuits, but the calculation speed becomes very slow
Solution Approach 1:
The patent replaces the traditional software-based matrix calculation mechanism with a hardware-based physical circuit generator. The physical circuit generator uses actual circuit components (resistors, capacitors, transistors, etc.) to physically embody the circuit being simulated, eliminating the need for matrix conversion and computational calculation. This substitution of hardware for software computation directly resolves the speed limitation while maintaining simulation capability.
Solution Approach 2:
The patent creates a physical copy of the virtual circuit structure by generating a corresponding physical circuit structure that mirrors the virtual circuit's topology and component characteristics. This physical copy is then used for simulation verification, allowing direct physical measurement and testing without computational approximation, thereby achieving both high speed and high precision.
2Extent of automation
If computer-based matrix calculation is used for simulation, then the simulation can be automated, but the simulation result may have large errors compared to actual situation
Solution Approach 1:
The patent replaces the computer-based computational system with a physical hardware system that directly replicates the circuit behavior. By using actual circuit components in the physical circuit generator, the simulation automatically captures real-world electrical characteristics, parasitic effects, and component variations without requiring mathematical models or approximations, thereby eliminating calculation errors.
Solution Approach 2:
The patent changes the fundamental parameter representation from abstract numerical values in matrix calculations to physical electrical parameters (voltage, current, resistance, capacitance) in the physical circuit. This parameter transformation allows the simulation to directly measure actual electrical behavior rather than computing approximate values, significantly improving accuracy while maintaining automation through automated test signal generation and measurement.
3Adaptability or versatility
If virtual circuit structure is converted to control signal and decoded, then the circuit can be regulated, but the process complexity increases
Solution Approach 1:
The patent introduces a control signal as an intermediary between the virtual circuit design and the physical circuit generation. The control signal encodes the circuit topology and component parameters, serving as a bridge that translates abstract design information into physical construction instructions. This intermediary approach enables automated regulation while managing complexity through standardized signal formats and systematic decoding procedures.
