Latest Patents

One of her latest patents is titled "Method of matching layout shapes patterns in an integrated circuit using Walsh patterns." This method focuses on matching patterns through an orthogonal sub-space projection of layout shapes using Walsh patterns. It performs a preliminary density feature extraction of a circuit design layout, allowing users to define a pattern and conduct a high-resolution search to locate all instances of that pattern. The method generates a sorted list of layout windows, ranging from the most similar to quantitatively less similar, significantly reducing false positives compared to prior art.

Another important patent is "Pattern-matching for transistor level netlists." This single pattern-matching algorithm allows for both exact and inexact pattern matching, enabling transistor-level design automation tools to perform various analyses prior to manufacturing custom logic. Circuit designers can specify which pattern external nets may be matched inexactly, while the remaining connections are matched using exact isomorphism constraints. This method reduces the number of patterns that circuit designers must generate and eliminates the need for an exponential number of patterns by providing an inexact pattern matcher.
