    摘要: An electronic device is disclosed comprising a transceiver stage (140) for communicating signals between the electronic device and a further device; and a baseband processor arrangement (120) implementing a built-in self test arrangement for testing the transceiver channels of the electronic device (100). The built-in self test arrangement further comprises a plurality of records, each record comprising predetermined response deviations to different test signals caused by a parametric fault; and means for selecting those records from the plurality of records for which the predetermined response deviation corresponds to the deviation of the received response. The present invention is based on the realization that a deviation of a response to a test signal from an expected value is dependent on specific parametric faults in specific components in the test signal path and, in addition, on the shape of the test signal. This information is stored in the BIST arrangement and is used to identify a parametric fault, if present, by subjecting the electronic device to a series of test signals.

    摘要: A method and apparatus for testing a static random access memory (SRAM) array for the presence of weak defects. A 0/1 ratio is first written to the memory array (step 100), following which the bit lines BL and BLB are pre-charged and equalized to a threshold detection voltage (step 102). The threshold detection voltage is programmed according to the 0/1 ratio of cells, so as to take into account specific cell criterion and/or characteristics. Next, the word lines associated with all of the cells in the array are enabled substantially simultaneously (step 104), the bit lines are then shorted together (step 106), the word lines are disabled (step 108) and the bit lines are released (step 110). Following these steps, the contents of the SRAM array are read and compared against the original 0/1 ratio (step 112). 10 Any cells whose contents do not match the original 0/1 ratio (i.e. those whose contents have flipped) are marked or otherwise identified as “weak” (step 114).

    摘要: Test vectors for structural testing of an analog circuit are selected by first selecting an initial set of test input vectors for the analog circuit. A set of faults is selected, comprising faults that each correspond to a respective node in the analog circuit and corresponding fault voltage value for that node. A measure of overlap is computed between probability distributions of test output signal values for the analog circuit in response to the test input vectors in the presence and absence of each of the faults from said set of faults respectively, as a function of estimated statistical spread of component and/or process parameter values in the analog circuit. Test input vectors are selected from the initial set of test input vectors for use in testing on the basis of whether the measure of overlap for at least one if the faults is below a threshold value in response to the selected test input vector under control of the test selection computer.
