Abstract
Search functions of a physical layout tool are performed by converting a given physical layout name and selected searching layout names from string representations into numerical representations and comparing the converted numerical representation of the given physical layout name with the converted numerical representations of searching physical layout names until a match occurs. In one embodiment, metal and via layer numbers included in string representations of physical layout names are converted to integer values by selecting number characters from predetermined positions in a string, such as number characters that identify the metal or via layer.
