Latest Patents

One of his latest patents is an integrated circuit apparatus and a power distribution network thereof. This invention provides a power distribution network that includes a top wiring layer, a bottom wiring layer, and a first conductive path. The top wiring layer features a first top trace and a second top trace extending along a first direction, while the bottom wiring layer includes a first bottom trace extending along a second direction. The first bottom trace has an electric potential equal to that of the first top trace, but different from that of the second top trace. The first conductive path connects the first top and bottom traces and includes a first upper conductive structure and a first lower conductive structure located directly under the first top trace and the second top trace, respectively. A signal wire preselected region is defined between the first upper conductive structure and the first bottom trace.

Another notable patent is a method and apparatus for performing power mesh optimization with the aid of additional wires. This method involves reading a clock cell definition file to obtain basic information about various clock cells in a circuit design. It executes a power mesh optimization procedure that classifies clock cells into sub-types based on their sizes and enhances the power mesh by adding additional wires crossing original wires at each clock cell.
