    摘要： A bridging fault detection system allows for a high amount of test coverage using a low number of test configurations. The bridging fault detection system automatically creates optimal test configurations and test vectors without the need for precise layout information, and is adaptable to complex programmable device architectures. Testers can specify a precise level of testing coverage to optimize the testing processing. A programmable device with interconnect bias circuitry decreases the number of test configurations and thus the time needed to test for bridging faults. The interconnect bias circuit provides explicit test control over the unused lines in a configuration, driving them both high and low for complete test coverage between each line and all of its possible neighbors. The bridging fault detection system balances the available number of control test points against the number of interconnect segments stitched together by programmable connection to maximize the lines under test per configuration.

    摘要： An embodiment of the present invention provides a programmable logic device (“PLD”) including one or more dedicated blocks of circuitry within one or more repairable logic array regions. Aspects of the present invention provide circuitry and methods for controlling shifting of programming data in normal and redundant modes for both dedicated block regions and fully repairable logic array regions during both regular and test programming sequences of a PLD. Other aspects provide circuitry and methods for interface routing between dedicated blocks and repairable logic array regions in both normal and redundant modes. Various other aspects are also disclosed.
