Definitions
- Each word of input data and output data has a plurality of bits, and the counter counts H logic data for each bit position in the word, and count information of the count value of H logic data for each bit position. Get it as.
- a plurality of counters are provided corresponding to a plurality of bit positions in a word, and have a counter that counts H logic data at the corresponding bit positions, and a number information storage unit corresponds to the plurality of counters. Store the number of H logic data that is provided by the corresponding counter for the input data.
- the timing generation unit 10 generates a reference clock that defines the operation of the test apparatus 100, and supplies the reference clock to each component of the test apparatus 100.
- the pattern generator 12 generates an address signal, a control signal, and a data for generating a test signal for testing the device under test 200. Data signal.
- the address signal designates the address of the device under test 200 to which the test signal is to be given, the data signal indicates the pattern of the test signal, and the control signal is a signal for controlling the operation of the waveform shaping unit 14.
- the device determination unit 20 compares the output signal read from the device under test 200 with the expected value signal, and determines pass / fail of the device under test 200.
- the device determination unit 20 is provided with an expected value signal for each address of the device under test 200, and compares the address of the device under test 200 with the read output signal, thereby determining the address of the device under test 200. The quality is judged every time.
- the fail memory 22 stores fail data indicating pass / fail of each address of the device under test 200.
- Each comparator 44 compares the number information of the output data signal output from the corresponding counter 38 and the number information of the input data signal stored in the corresponding number information storage unit 40.
- each comparator 44 is an exclusive OR circuit, and outputs 0 when the number information matches, and outputs 1 when the number information does not match.
