Aspects of the invention provide for the maintenance of user modified portions of a map between a test bench and a test set generator during an iterative electronic design process. Various implementations of the invention provide for matching sections within a design for an electronic device with corresponding sections in a map between the elements in the design to elements in a graph representation of the design. The matched sections are then compared to determine if any discrepancies exists, such as, for example, if the design has been recently changed. If any discrepancies do exist, then it is determined whether the section of the map can be updated or must be replaced entirely to resolve the discrepancies. Various implementations of the invention provide that the process can be repeated during an iterative design flow such that as the design is modified during the iterative design flow, the map can be updated to reflect the changes.
