This paper presents a method to diagnose faults in FPGA interconnection resources. A single fault model is given. Under the given model, a diagnosing method is proposed. At most five programming steps in the proposed method is required if adaptive testing scheme is used. For non-adaptive test, eight programming steps is required to diagnose all the possible faults under the given single fault model. The accuracy of the fault diagnosing is one segment for a segment stuck-at or stuck-open fault, a segment pair for a bridge fault, a switch for switch stuck-on or stuck-off fault.
