Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex physical systems, such as modern electrical circuits, require advanced design tools to manage intricate interactions and operational domains, where existing technologies struggle to seamlessly integrate logical and physical data abstractions, leading to inefficiencies in design time and accuracy.
Innovation Solution
A system that allows users to interact with a data processing machine to control the presentation of display data, using a combination of physical and logical topological contexts, where subsystem design data is partitioned and mapped to logical and physical topologies, enabling efficient design and verification of sub-circuits across multiple design stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical and logical data abstractions are integrated in existing design tools, then design completeness is improved, but design complexity and time consumption increase
Solution Approach 1:
The patent divides the design data into separate physical and logical abstractions that can be independently managed and processed. Physical abstraction handles spatial relationships and component placements, while logical abstraction handles functional relationships and circuit behavior, allowing parallel processing and reducing overall design time
Solution Approach 2:
The patent introduces a topology template as an intermediary structure that bridges physical and logical abstractions. The topology template defines standardized logical topologies that can be automatically mapped from physical layouts, reducing the complexity of direct integration while maintaining design completeness
2Manufacturing precision
If detailed physical topology data is maintained, then manufacturing precision is improved, but data complexity increases
Solution Approach 1:
The patent extracts the essential topological relationships from detailed physical topology data and represents them in simplified logical abstraction. Only the necessary connectivity and spatial relationship information is retained in the logical model, while detailed physical geometry data is separated, reducing data complexity while preserving manufacturing precision through the physical abstraction
Solution Approach 2:
The patent transforms complex multi-dimensional physical topology data into standardized two-dimensional topology templates that represent logical relationships. This dimensional transformation simplifies the data structure by projecting complex spatial relationships onto standardized template frameworks that are easier to manage and process
3Adaptability or versatility
If logical topology is decoupled from physical layout, then design flexibility is improved, but verification difficulty increases
Solution Approach 1:
The patent implements automated verification mechanisms that provide feedback between logical and physical abstractions. The system automatically checks consistency between topology templates and physical layouts, detecting mismatches and errors without requiring manual verification, thus reducing verification difficulty while maintaining design flexibility
Solution Approach 2:
The patent performs preliminary consistency checks and validation during the design process itself, rather than as a separate post-processing step. The verification rules are embedded in the design flow, automatically checking logical-physical consistency as designs are created and modified, making verification easier and more integrated
Data Source
AI summary
A design system provides data structures to store parameters of physical structures that can be viewed and modified through a graphical design interface. Certain of the structures of the physical system may be partitioned into a subsystem such that the data describing the subsystem includes physical topology data defining relative locations of the structures in the physical system. The physical topology data is back-annotated into a logical topology, such as in accordance with a predefined logical topology template. The logical data abstraction of the circuit design is kept synchronized with the physical data and presented in a logical topology that is kept legible through the prudent selection of logical topologies representing the physical subsystem design.
