3D Model Simplification for Multilayer Metal Circuit Simulation

The complete 3D model is segmented into non-simplified regions (requiring detailed modeling) and simplified regions (where detailed geometry is not needed). This segmentation allows the simulation to focus computational resources on critical areas while using simplified representations elsewhere, thereby maintaining accuracy where needed while reducing overall simulation time.

Different regions of the 3D model are assigned different levels of detail based on their importance to signal transmission. Critical regions near high-speed signal paths retain complete geometric detail, while non-critical regions use simplified representations. This local differentiation maintains simulation accuracy for important areas while reducing computational burden in less important areas.

The system performs automatic identification of non-simplified regions based on predefined criteria related to signal transmission paths, ground connections, and via distributions. The algorithm independently determines which regions require detailed modeling without requiring manual engineer intervention, thereby achieving full automation while capturing the essence of expert judgment through programmed rules.

Manual engineer judgment and experience are replaced by an automated algorithmic system that uses computational rules to identify critical regions. The mechanical process of manual model review and modification is substituted with an automated computational approach that applies consistent criteria across all designs, eliminating dependence on individual engineer expertise while maintaining quality standards.

The model is divided into segments based on their functional importance to signal integrity. By segmenting the design into critical and non-critical regions, the system preserves detailed geometry only where it impacts design reliability, while using simplified representations elsewhere. This reduces computational complexity while maintaining design integrity in areas that matter most.

Non-essential geometric details are extracted and removed from regions where they do not impact signal transmission or electrical performance. By taking out unnecessary complexity from non-critical regions while retaining detailed modeling in critical areas, the system reduces overall computational complexity while preserving design integrity where it is most needed.
