Abstract
A structure and method of designing an integrated circuit includes generating at least one device shape, altering the device shape to comply with predetermined rules, forming a first hierarchical level abstraction around the device shape (where the first hierarchical level abstraction represents a perimeter of the device shape), preparing a first hierarchical level arrangement of first hierarchical level abstractions, altering the first hierarchical level arrangement to comply with the predetermined rules, forming a second hierarchical level abstraction around the first hierarchical level arrangement (where the second hierarchical level abstraction represents a perimeter of the first hierarchical level arrangement), preparing a second hierarchical level arrangement of second hierarchical level abstractions, and altering the second hierarchical level arrangement to comply with the predetermined rules.
