1. A method of processing microdevice layout design data, comprising: with a computer, analyzing microdevice layout design data to identify instances of a first type of geometric element, identify instances of a second type of geometric element, and for identified instances of the first type of geometric element, determine if the identified instance of the first type of geometric element shares the defined relationship with one or more instances of the second type of geometric element, and when the instance of the first type of geometric element shares a defined relationship with one or more instances of the second type of geometric element in the microdevice layout design data, then creating a cluster data object associating the instance of the first type of geometric element with the one or more instances of the second type of geometric element.
