Latest Patents

Among his latest patents is the "Shape-based geometric database and methods and systems for construction and use thereof." This invention introduces a shape-based geometric database that utilizes R-trees to compactly and efficiently represent design objects. The R-trees are populated in a balanced manner, improving their utility in various stages of circuit design. For instance, tiles are assigned to bins based on their orientation and proximity to reference tracks with similar orientations. Additionally, bin R-trees and direction and layer R-trees are defined using a level sequential process, culminating in the establishment of a root node for each case.

Another notable patent is the "Short path search using tiles and piecewise linear cost propagation." This method focuses on finding the shortest paths through a compact tile graph using a piecewise linear cost model. It ensures that a shortest path can always be identified in a computationally effective manner. The approach involves cost function propagation from tile segment to tile segment, allowing for efficient searching from a source location to a target location.
