Latest Patents

One of his latest patents is titled "Legalizing a multi-patterning integrated circuit layout." This invention involves a method for legalizing a multi-patterning integrated circuit layout that includes a plurality of islands. A set of multi-patterning constraints is generated based on conflicts identified between these islands. The method combines general design rule constraints with multi-patterning constraints to create a comprehensive set of layout constraints. The feasibility of these constraints is then checked and provided to a Linear Program solver to generate an output circuit layout.

Another significant patent is "Automatic layout modification tool with non-uniform grids." This method and system automatically legalize a circuit layout with layout objects in the presence of multiple non-uniform grids. It involves generating a set of layout constraints that include design rule constraints and gridding requirements. The method processes these constraints into a feasible form using Boolean variables, identifies infeasible layout constraints, and resolves them through a constraint relaxation process. Ultimately, it generates an output circuit layout for user display by solving the set of layout constraints.
