  • Publication number: 20230408581
    Abstract: Techniques for interface conversion and unicast for test content, firmware, and software delivery are described. An example apparatus comprises a scan test interface coupled to multiple circuits blocks to perform a scan test for the multiple circuit blocks, and circuitry coupled to input/output (IO) signals of the scan test interface to provide content for the multiple circuit blocks and to deliver a replicated content to multiple endpoints of the multiple circuit blocks (e.g., unicast technology). In another example, the circuitry is coupled to the IO signals of the scan test interface and a system/communication interface to decode packets received at the IO signals and convert the decoded packets to provide content through the system/communication interface for the multiple circuit blocks. Other examples are described and claimed.

  • Publication number: 20120159274
    Abstract: Techniques are disclosed relating to testing logic in integrated circuits using an external test tool. In one embodiment, an integrated circuit includes a logic unit and a self-test unit. The self-test unit is configured to receive an expected signature value that corresponds to an expected output value of the logic unit, and to compare the expected signature value and an actual signature value generated from an actual output value from the logic unit. In some embodiments, the integrated circuit further includes a pseudo-random pattern generator configured to provide an input value to the logic unit, and the logic unit is configured to generate the actual output value based on the provided input value. In some embodiments, the integrated circuit further includes a multiple-input signature register (MISR) configured to generate the actual signature value based on the actual output value and a seed value.

  • Patent number: 7945823
    Abstract: A built-in self-test (BIST) circuit for testing addressable locations can include a BIST generator (202) that can generate test addresses for testing each addressable location. Defective addresses can be stored in a fault address store (216). An address range selector circuit (230) can limit the range of addresses generated by an address generator (234). Once defective addresses for a first range have been detected, an address range selector circuit (230) can test another range. An entire address range can thus be tested regardless of the depth of a fault address store (216).

  • Patent number: 7447958
    Abstract: A parallel data transmission test system can include a receiver section (100) having input selector circuits (104-O to 104-N) that provide a received test data to logic adjust circuits (106-O to 106-N) that “logically align” multiple incoming test values to remove intentionally introduced logic difference (e.g., inversion) with respect to one another. Result combining circuit (108) can logically combine output data values and provide a resulting sequence to a pattern sequence test circuit (110).
