Techniques for monitoring the performance of a programmable circuit and to provide an early warning of a potential failure are provided. A processor monitors the performance of components on a programmable circuit over time. The processor stores performance characteristics for the components in memory. If the performance characteristics for particular components fall outside tolerance ranges, these components may to fail to operate according to specifications. Once the performance characteristics for particular components are outside the tolerance ranges, the processor sends out an alert signal. The alert signal indicates the possibility that the performance of the programmable circuit may violate the specifications in the future. The processor may repair the programmable circuit by re-routing around the problem components.
