Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional track pattern representation in electronic design does not support region-based track patterns, non-uniform pitches, and area-specific constraints, making it challenging for advanced manufacturing requirements, especially for interactive layout editing and routing tasks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional track pattern representation is used, then the design process is simpler, but it does not support region-based track patterns, non-uniform pitches, and area-specific constraints
Solution Approach 1:
The patent divides the design space into distinct regions, each with its own track pattern characteristics. Track patterns are segmented by region boundaries, allowing different pitch values, orientations, and constraints to be applied to different areas of the same layer without affecting the entire design.
Solution Approach 2:
The patent enables local customization of track patterns by associating specific track definitions with particular regions. Each region can have unique track pitch, orientation, and spacing characteristics tailored to local routing requirements, while maintaining consistency within each region.
2Adaptability or versatility
If area-bounded tracks with spacetiles are implemented, then routing flexibility and compliance with complex grid requirements are improved, but the device complexity increases
Solution Approach 1:
The patent performs preliminary generation of spacetiles based on track pattern definitions and region boundaries before the actual routing process. This pre-computation creates a structured framework that guides subsequent routing operations, reducing the complexity of real-time routing decisions.
Solution Approach 2:
The patent introduces spacetiles as an intermediary data structure that mediates between the high-level track pattern definitions and the detailed routing operations. Spacetiles serve as a intermediate representation that simplifies the interaction between routing algorithms and complex track constraints.
3Manufacturing precision
If track patterns are bounded within designated areas, then manufacturing precision is improved, but the ease of operation decreases
Solution Approach 1:
The patent provides feedback mechanisms that monitor track pattern placements against region boundaries and constraints. The system automatically detects violations of track bounds and provides guidance to users, ensuring manufacturing precision while maintaining ease of operation through intelligent assistance.

AI summary
Disclosed are methods, systems, and articles of manufacture for implementing a physical electronic design with area-bounded tracks. One aspect identifies an area in an electronic design and a track pattern associated with the area, identifies active tracks in the track pattern, and creates spacetiles with the active tracks. This aspect uses area-based search probes based on spacetiles to find viable implementation solutions to implement the area in the electronic design. Another aspect identifies a tracked area associated with a track pattern and a trackless area and use spacetile(s) and a via spacetile layer to transition between the tracked area and the trackless area for implementation of the electronic design in the tracked or the trackless area of the electronic design.
