  • Method and mechanism for determining shape connectivity
    Patent number: 8209643
    Abstract: A method and mechanism is disclosed for identifying connected shapes and objects in an electrical design. The entire hierarchical design does not have to be flattened to perform the operation of identifying connected objects for a specific object. Instead of unfolding the entire design hierarchy, only the specific instances of shapes falling within the geometric bounds of shapes need to be unfolded to perform the search.
