Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If signals are transmitted through physically adjacent transmission lines at high speed, then transmission speed and integration are improved, but crosstalk between transmission lines increases causing signal errors
Solution Approach 1:
The patent applies dynamic remapping of data to transmission lines based on real-time crosstalk analysis. The system dynamically adjusts which data signals are assigned to which transmission lines by analyzing data patterns and calculating crosstalk scores, thereby adapting the transmission configuration to minimize interference while maintaining high-speed operation
Solution Approach 2:
The system changes the mapping parameter between data signals and transmission lines by remapping data to different transmission lines based on calculated crosstalk scores. This parameter change optimizes the transmission configuration by assigning data with high crosstalk scores to different transmission lines, thereby reducing signal interference and improving transmission reliability
2Reliability
If data remapping is performed to reduce crosstalk, then signal transmission quality is improved, but device complexity increases due to additional analysis and remapping circuits
Solution Approach 1:
The system performs preliminary analysis of data patterns before transmission to identify potential crosstalk issues. By analyzing the data pattern of each data signal in advance and calculating crosstalk scores beforehand, the system determines the optimal transmission line assignment prior to actual data transmission, preventing crosstalk rather than correcting it
Solution Approach 2:
The system uses the data patterns themselves to generate the remapping strategy. By analyzing the inherent characteristics of the data being transmitted and calculating crosstalk scores based on these patterns, the system self-determines the optimal transmission configuration without requiring external control or complex preset configurations
