    Abstract: A wrapper for automatic test pattern generation uses the functional bus when testing cores on an integrated circuit device. The functional bus is between the bus wrapper and the cores. During normal operation, the functional bus operates as a standard bus to communicate functional inputs and outputs between the cores and in/out of the integrated circuit device. During test operation, test signals are communicated on the functional bus. As a result, each core does not require its own wrapper; this allows the bus wrapper to reduce the area occupied by test circuitry.

    Abstract: An integrated circuit product package configured to continuity testing is described. The integrated circuit product package includes a package substrate. The package substrate includes internal routing connections. The integrated circuit product package also includes a semiconductor die coupled to the package substrate. The semiconductor die includes input/output (I/O) pins and switches. The switches selectively coupled the I/O pins to facilitate a daisy chain connection. The daisy chain connection includes circuitry fabricated on the semiconductor die, more than two of the internal routing connections, more than two of the I/O pins and at least one switch.

    Abstract: A method and apparatus for adaptive test time reduction is provided. The method begins with running a predetermined number of structural tests on wafers or electronic chips. Pass/fail data is collected once the predetermined number of structural tests have been run. This pass/fail data is then used to determine which of the predetermined number of structural tests are consistently passed. The consistently passed tests are then grouped into slices within the test vectors. Once the grouping has been performed, the consistently passed tests are skipped when testing future production lots of the wafers or electronic chips. A sampling rate may be modulated if it is determined that adjustments in the tests performed are needed. In addition, a complement of the tests performed on the wafers may be performed on the electronic chips to ensure complete test coverage.
