His innovative methodologies have advanced the way clock distribution and noise estimation are handled in integrated circuits.

Latest Patents

One of his latest patents is titled "Clock skew verification methodology for grid-based design." This invention provides a method and apparatus for determining clock insertion delays in microprocessor designs that utilize a grid-based clock distribution. The process involves partitioning the complete clock net into a global clock net and several local clock nets. It includes simulating loads for each local clock net, simulating the global clock net, and combining these simulations to form the complete clock net. The method evaluates the combination to check for convergence and stores the results in a Clock Data Model. If the results do not converge, the method re-simulates the local and global clock nets. The Clock Data Model is essential for managing and querying all simulation information, and it can analyze the complete clock net to predict clock skew for potential redesigns.

Another notable patent is the "System and method for topology based noise estimation of submicron integrated circuit designs." This tool computes noise coupled onto victim lines from aggressor lines within an integrated circuit. It includes code for traversing a victim line to measure its length, average width, coupling length, and spacing between the victim and aggressor lines. The tool computes resistance, estimated coupling capacitance, and total capacitance of the victim line based on these parameters.
