Latest Patents

One of his latest patents is titled "Method of matching layout shapes patterns in an integrated circuit using Walsh patterns." This innovative method allows for the matching of patterns based on an orthogonal sub-space projection of layout shapes using Walsh patterns. It performs a preliminary density feature extraction of a circuit design layout, enabling users to define a pattern and conduct a high-resolution search to locate all instances of that pattern. The method significantly reduces false positives compared to prior art and allows for the reuse of density data as the window is stepped across the layout.

Another significant patent is the "Method for testing the validity of initial-condition statements in circuit simulation, and correcting inconsistencies thereof." This method and system validate initial conditions provided by users when simulating VLSI circuits. It detects inconsistent initial condition sets and replaces them with consistent subsets. The method selects resistance and source values in a Norton or Thevenin circuit to enforce the initial conditions and correlates the consistent initial conditions with an equivalent circuit. This allows users to be notified of inconsistencies and provides a measure of their severity.
