Latest Patents

One of his latest patents is titled "Method for calculating capacitance gradients in VLSI layouts using a shape processing engine." This patent describes a method for computing the gradients of capacitances in an integrated circuit chip layout with respect to design and process parameters. It includes a shape processing engine in the form of a variational mapping engine and a capacitance calculation engine that features a gradient calculation engine. The variational mapping engine translates physical parameter variations into variations on the edges of the elementary patterns that the layout of the integrated circuit is decomposed into. The gradient calculation engine computes capacitance gradients by combining information from two sources: pre-existing gradients in a capacitance lookup table and analytical expressions of capacitance correction factors.

Another notable patent is the "System and method for three-dimensional variational capacitance calculation." This patent provides capacitance extraction techniques and outlines a method for analyzing variational coupling capacitance between conductors in an integrated circuit design. The method involves computing coupling capacitance between conductors of interest using a set of floating random walk paths. It also includes perturbing one or more conductors and modifying any affected floating random walk paths. The coupling capacitance is then recomputed to include the modified paths.
