ABSTRACT:
In order to reduce the amount of work that must be done to implement a revised circuit design in physical circuitry, portions of the new design that are the same as a previously implemented design are identified. This preferably involves several different, successively applied approaches to attempting to find matching circuit components in the new and old designs. Connections that have changed between otherwise unchanged components are also identified. The physical circuit implementation of the unchanged portions of the old design can be reused in the implementation of the new design, thereby reducing the amount of new physical circuit implementation work that must be done.
