Electronic Design Aperture Patching for Disconnected Field Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pseudo-3D modeling approaches in electronic design often result in disconnected electromagnetic field domains, leading to inaccurate analysis of electrical properties and electromagnetic fields due to the reduction of three-dimensional features to two-dimensional models, which can erroneously model a short circuit as an open circuit, and the introduction of a single floating plane to address this issue disturbs the design and introduces further inaccuracies.
Innovation Solution
A method is introduced to identify and selectively patch apertures in multi-layered electronic designs using hybrid or 2.5D solvers, without relying on 3D solvers, by discretizing metal shapes, identifying apertures, and adding patches to cover these apertures, thereby maintaining accurate electrical behavior analysis across a range of frequencies.

Engineering Contradiction Analysis
1Productivity
If conventional pseudo-3D modeling approaches are used to reduce computational complexity and analysis time, then productivity and ease of operation are improved, but manufacturing precision and measurement precision deteriorate due to disconnected field domains causing inaccurate electrical property analysis
Solution Approach 1:
The patent segments the electromagnetic field domain into multiple connected regions by introducing conductive structures at apertures where field domains are disconnected. This segmentation approach maintains computational efficiency of pseudo-3D methods while restoring accuracy by ensuring continuous field domains for accurate electrical property analysis.
Solution Approach 2:
The patent introduces conductive structures as intermediary elements at aperture locations to connect disconnected field domains. These conductive structures act as mediators that restore field continuity without requiring full 3D modeling, thus maintaining computational efficiency while improving analysis accuracy.
2Stability of the object's composition
If a single floating plane is inserted to cover the entire area and provide continuity paths for disconnected field domains, then field domain connectivity is improved, but manufacturing precision deteriorates due to design disturbance and inaccurate electrical property results
Solution Approach 1:
Instead of using a single floating plane covering the entire area, the patent segments the solution by placing conductive structures only at specific aperture locations where field domains are disconnected. This targeted approach maintains field connectivity where needed while minimizing disturbance to the overall design.
Solution Approach 2:
The patent applies local quality by introducing conductive structures only at specific locations (apertures) where field domain disconnection occurs, rather than uniformly across the entire design area. This localized intervention maintains field connectivity where necessary while preserving design accuracy in other regions.
3Productivity
If pseudo-3D approaches reduce three-dimensional features to two-dimensional modeling for expediency, then productivity is improved, but manufacturing precision worsens due to erroneous modeling of short circuits as open circuits
Solution Approach 1:
The patent addresses the dimensionality reduction problem by strategically placing conductive structures at aperture locations in the 2D model to represent 3D field continuity. This approach maintains the computational efficiency of 2D pseudo-3D modeling while restoring accuracy in representing three-dimensional electromagnetic field behavior.
Solution Approach 2:
Conductive structures are introduced as intermediary elements in the 2D model to represent the effect of 3D field continuity. These intermediaries allow the 2D model to accurately capture 3D electromagnetic behavior at critical locations without requiring full 3D modeling complexity.
