  • Functional failure analysis techniques for programmable integrated circuits
    Patent number: 7685485
    Abstract: Techniques are provided for isolating failed routing resources on a programmable circuit. Failing test patterns and the test logs are fed to a Statistical Failure Isolation (SFI) tool. The SFI tool extracts failing paths from the test patterns. A statistical analysis is performed on interconnect resources related to failing paths. The resources on the paths are then tallied to create a histogram of resources. These resources are then be fed into an Adaptive Failure Isolation (AFI) tool to auto-generate verification patterns. A tester uses the verification patterns to isolate failed interconnect resources.
