IC Floorplan Layout With Wrapped Logic Around Interface Circuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional integrated circuit floorplans inefficiently utilize corner regions and may lead to timing violations due to significant distances between input-output and logic circuitry, causing resource contention and suboptimal performance, especially in designs with strict timing requirements.
Innovation Solution
The integrated circuit floorplan design includes an interface circuit region surrounded by logic circuitry on multiple sides, with the logic circuitry wrapping around the interface circuit to minimize signal transmission pathways and prevent resource contention, optimizing the use of corner regions and improving timing compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interface circuitry is placed at corner regions of the peripheral region, then the integrated circuit can accommodate more interface circuitry along the periphery, but the corner regions are not fully utilized and signal transmission distance increases
Solution Approach 1:
Instead of placing interface circuitry only at corners or only along edges, the patent inverts the conventional approach by allowing logic circuitry to extend into corner regions and wrap around interface circuitry blocks positioned along the periphery, thereby fully utilizing corner areas while maintaining short signal paths
Solution Approach 2:
The logic circuitry is nested around the interface circuitry blocks, forming a wrapping pattern where logic regions surround the interface regions on multiple sides, creating an optimized spatial relationship that minimizes signal transmission distance
2Adaptability or versatility
If interface circuitry is located at corner regions, then peripheral interface capacity is increased, but significant distance to core logic results in timing violations
Solution Approach 1:
The patent applies local quality by creating different spatial zones: interface circuitry blocks are positioned along the periphery for high interface capacity, while logic circuitry is strategically placed in corner regions and wrapped around the interface blocks to ensure short local signal paths, thereby achieving both high capacity and fast signal transmission
Solution Approach 2:
The patent transitions from a conventional planar layout to a multi-dimensional wrapping configuration where logic circuitry surrounds interface circuitry on multiple sides (top, bottom, left, right), creating a three-dimensional spatial relationship that minimizes signal transmission distance in all directions
3Adaptability or versatility
If interface circuitry occupies peripheral region, then interface functionality is provided, but resource contention occurs with logic circuitry at core corners
Solution Approach 1:
The patent segments the integrated circuit into distinct interface circuitry blocks positioned along the periphery and logic circuitry regions that wrap around them, creating clearly defined functional zones that eliminate resource contention by providing dedicated access paths for each interface block
