  • Patent number: 9746516
    Abstract: A failing latch is identified on a chip including a plurality of latches with the failing latch receiving data propagated from a first set of test input latches. A diagnostic set of latches is determined which includes the failing latch and a set of related latches. The set of related latches each receives data propagated from at least one test input latch from the first set of test input latches. The set of related latches is identified from a related latches table. One or more tests are performed on the chip and test output data is collected from the diagnostic set of latches. The related latches table is created by tracing from a target latch.

  • Patent number: 9188636
    Abstract: A method and structure tests a system on a chip (SoC) or other integrated circuit having multiple cores for chip characterization to produce a partial good status. A Self Evaluation Engine (SEE) on each core creates a quality metric or partial good value for the core. The SEE executes one or more tests to create a characterization signature for the core. The SEE then compares the characterization signature of a core with a characterization signature of neighboring cores to determine the partial good value for the core. The SEE may output a result to create a full characterization map for detailed diagnostics or a partial good map with values for all cores to produce a partial good status for the entire SoC.

  • Patent number: 9003244
    Abstract: A method of performing a dynamic built-in self-test (BIST). The method includes performing a first test of a circuit on a semiconductor chip. The first test includes a first switch factor. The circuit during the first test is monitored with one or more sensors. A first sensor value of one or more sensors monitoring the circuit is determined. It is also determined whether the first sensor value is within a range of a programmable constant. A second switch factor is determined in response to determining that the first sensor value outside the range of the programmable constant.
