Title: Method of determining signal delay of a resource in a reconfigurable system having multiple resources

Abstract: An arrangement for configuring a reconfigurable system having a plurality of resources includes a compiler that configures the resources to implement a functional system in accordance with a user design. A defect database is also provided that (1) stores information indicating which of the resources is defective when the resources contain at least one defective resource, and (2) supplies the information to the compiler such that the compiler does not use the defective resource when the compiler configures the resources to implement the user design. The arrangement also includes a detection subsystem that repeatedly and redundantly tests operational condition of the resources grouped in different groups to detect the defective resources.
