Abstract
An expert system for performing a redesign operation in connection with an original design. A working memory includes a plurality of blackboards each for storing a design representation and desired operational characteristics. A simulation component comprises a plurality of simulators each for generating simulated operational characteristics in connection with a design representation on one of said blackboards. A diagnostic component identifies operational discrepancies between the simulated operational characteristics and the desired operational characteristics and the causes of the operational characteristics. A redesign component generates a redesign of the design representations on the blackboards in response to the original design and the identified dicrepancies and discrepancy causes.
