1. A method of verifying a microdevice layout design, comprising: receiving first feature input data identifying a first type of geometric element in a layout design; receiving second feature input data identifying a second type of geometric element in a layout design; receiving relationship input data defining a relationship between geometric elements; analyzing a microdevice layout design to identify instances of the first 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 if the instance of the first type of geometric element shares the defined relationship with one or more instances of the second type of geometric element in the microdevice layout design, 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.
