Latest Patents
One of Groeneveld's latest patents is titled "Method for storing multiple levels of design data in a common database." This innovative approach utilizes a common database to store design data at various stages of the design process, including data-flow graphs, netlists, and layout descriptions. By eliminating the need to translate circuit descriptions between tools, this method significantly increases speed, flexibility, and integration. The common database comprises entities, models, cells, pins, busses, and nets, with data-flow graphs stored as graphs, nodes as cells, and edges as busses. Additionally, physical design data is efficiently managed by storing cells in a model using a KD tree, allowing for effective queries on cells located within arbitrary areas of the layout.
Another significant patent by Groeneveld is the "Method of designing a constraint-driven integrated circuit layout." This automated method leverages a computer to design an integrated circuit layout based on an electronic circuit description and a selected plurality of cells from a cell library. The process involves several steps, including assigning cells to designated buckets on the layout, performing global routing to connect selected cells, and executing detailed placement and routing to finalize the integrated circuit layout.
