This paper considers the system redesign problem where an existing digital electronic system must be redesigned for reasons such as better performance, technology upgrade, lower power, and so on. The designer may wish to retain certain design for purely, technical reasons or reasons of propriety. We presented an algorithm based on the evolutionary paradigm for optimally redesigning an existing design. A tool called GRAFT which implements the evolutionary algorithm is described.
