Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for manual routing in integrated circuit design are cumbersome and require extensive expertise, especially when dealing with multiple metal layers, making it difficult for designers to intuitively understand and debug design issues in a two-dimensional view.
Innovation Solution
The implementation of design context projection and wire editing in augmented reality media allows for a three-dimensional visualization of localized design areas, enabling users to manipulate and edit metal layers using hand gestures, thereby simplifying the routing process and reducing the need for keyboard and mouse interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional two-dimensional manual routing methods are used for integrated circuit design, then designers can work with existing tools and workflows, but the process becomes cumbersome and requires extensive expertise, especially when dealing with multiple metal layers
Solution Approach 1:
The patent transforms the traditional two-dimensional circuit design interface into a three-dimensional augmented reality environment. Designers can visualize and manipulate circuit layouts, metal layers, and routing paths in 3D space, providing intuitive spatial understanding of complex multi-layer designs without requiring extensive expertise in traditional 2D routing conventions
Solution Approach 2:
The patent introduces an augmented reality system as an intermediary between the designer and the circuit design data. This AR mediator presents simplified visual representations of complex routing information and enables natural hand gesture interactions, reducing the operational complexity while maintaining full design capability
2Difficulty of detecting and measuring
If traditional two-dimensional views are used for design debugging, then existing debugging workflows can be maintained, but designers find it difficult to intuitively understand and debug design issues
Solution Approach 1:
The patent enhances design debugging by projecting circuit design data into three-dimensional augmented reality space. This allows designers to visually detect routing errors, design rule violations, and spatial conflicts with immediate visual feedback, maintaining full design information while dramatically improving intuitiveness and reducing the difficulty of detecting design issues
3Productivity
If extensive keyboard and mouse interactions are required for wire editing, then precise control can be achieved, but the routing process becomes time-consuming and less efficient
Solution Approach 1:
The patent replaces the mechanical keyboard and mouse interaction system with a hand gesture-based control system in augmented reality. Designers can select, manipulate, and edit wires and routing paths using natural hand movements in 3D space, dramatically improving routing efficiency while maintaining precise control over design elements

AI summary
Embodiments are for using design context projection and wire editing in augmented media. Responsive to receiving an indication of an error in a design for an integrated circuit (IC), a localized area is extracted encompassing the error in the design. Augmented reality media of the localized area of the design is generated with a guide pattern, the localized area including objects. The augmented reality media of the localized area is caused to be presented in a three-dimensional (3D) projection on an augmented reality device for a user. Responsive to receiving at least one modification to the augmented media in the 3D projection, the design for the IC is updated with the modifications.
