Abstract: Methods and systems provide aspects of electronics layout design including copying of layout element(s) and graphically defining a one-to-one correspondence between two elements. An exemplary method may include defining a cloning constraint for a layout, rendering a user interface (UI) to display at least one of a schematic and form representation of the layout, and receiving a selection of at least one element in the layout. The method may create a movable drag set based on the selection, and responsive to a matching of at least one element of the drag set with another element in the layout, performing a one-to-one correspondence for the matched elements. The matching may be an overlap of at least one element in the drag set with an element in the layout having the same master.

Abstract: Various embodiments implement electronic designs with cloning techniques by identifying a root device corresponding to a master design in an electronic design, performing one or more sets of searches for device correspondence with respect to the root device, and implementing the electronic design by at least characterizing the device correspondence based at least in part upon one or more criterion for the one or more sets of searches. These techniques implement the electronic design by characterizing the device correspondence through at least determining whether the device correspondence represents a clone, a mutant, or a user clone and by identifying and replicating clones, mutants, and/or user clones in the electronic design.
