Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional methods for automatic wiring of printed circuit boards are labor-intensive and time-consuming, especially with large-scale integrations (LSIs) having faster signal speeds and more pins, as they require manual accumulation and construction of knowledge bases for wiring strategies.
Innovation Solution
A method and apparatus that automatically create wiring path information by sorting signals into groups, generating wiring paths indicating scanning areas for signal clusters, displaying these paths on printed board data, and controlling the created information to simplify the design process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual knowledge accumulation and construction of wiring strategy is performed, then wiring quality can be maintained, but design period is considerably prolonged
Solution Approach 1:
The patent creates wiring path information that serves as a template or model for automatic wiring. This wiring path information is generated by analyzing the wiring strategy and converting it into structured data that can be automatically processed, effectively copying the essential wiring patterns without requiring manual execution of each wiring operation.
Solution Approach 2:
The patent replaces the manual mechanical process of knowledge accumulation and wiring strategy construction with an automatic information processing system. The system automatically generates wiring path information by processing wiring strategy data, eliminating the need for manual knowledge base accumulation and significantly reducing design time while maintaining wiring quality.
2Reliability
If manual wiring strategy construction is performed, then wiring knowledge can be applied, but labor load of designer is heavy
Solution Approach 1:
The patent enables the system to automatically generate wiring path information from wiring strategy data without requiring continuous manual intervention. The automatic wiring process uses the generated wiring path information to perform wiring operations independently, allowing the system to serve itself rather than requiring constant designer input, thus reducing labor load while maintaining reliable application of wiring knowledge.
Solution Approach 2:
The patent extracts the essential wiring knowledge and strategy from manual processes and converts it into structured wiring path information. This extraction separates the knowledge application aspect from the manual labor aspect, allowing the knowledge to be systematically applied through automatic processing while eliminating the heavy manual labor component.
3Productivity
If automatic wiring is performed without pre-generated wiring path information, then processing speed can be increased, but wiring quality deteriorates
Solution Approach 1:
The patent performs preliminary action by generating wiring path information before the actual automatic wiring process. This pre-generated information contains optimized wiring paths and scanning areas that guide the automatic wiring process, ensuring that high-quality wiring results are achieved while maintaining fast processing speeds. The preliminary generation of wiring path information eliminates the need for real-time decision-making during wiring, thus preserving both speed and quality.
Data Source
AI summary
A wiring processing apparatus decides each group formed by sorting signals that flow between component pins. Then, the wiring processing apparatus reads printed circuit board data and identifies a net cluster that belongs to each group. After a net cluster that belongs to each group is identified, the wiring processing apparatus refers to the printed circuit board data about the identified net cluster, and automatically creates each wiring route that indicates a wiring scanning area of the signal cluster in each group. Thus the wiring processing apparatus displays them on the printed board data. After the wiring route is automatically created, the wiring processing apparatus automatically creates wiring route information that corresponds to each wiring route, and controls them according to each wiring route.
