Title: Innovations of Wai-Yan Ho in Integrated Circuit Design
Introduction
Wai-Yan Ho is an accomplished inventor based in Cupertino, CA, known for his contributions to the field of integrated circuit design. He holds a total of 3 patents that focus on improving the efficiency of design rule checks and layout verification processes.
Latest Patents
His latest patents include methods for layout overlap detection with selective flattening in computer-aided design. The first patent describes a method for efficiently performing hierarchical design rules checks (DRC) and layout versus schematic comparison (LVS) on layout areas of an integrated circuit where cells overlap or where a cell and local geometry overlap. This invention utilizes a hierarchical tree to describe the integrated circuit's layout data, allowing for efficient layout verification by performing LVS and DRC checks on overlapping cells. The method determines overlap areas using predefined data structures that divide each cell into an array of spatial bins. Once overlap is detected, the areas of the layout data corresponding to the overlap areas are selectively flattened before proceeding to DRC and LVS processing.
The second patent also focuses on selective flattening in layout areas in computer-implemented integrated circuits. It shares similar methodologies to the first patent, emphasizing the importance of efficient layout verification and the traversal of the hierarchical tree from the top cell down to the leaf nodes. This approach ensures that geometry data is pushed directly to the top cell without being stored in intermediate locations, providing an effective mechanism for selective flattening.
