Abstract
A fuzzy scoreboard can compute, using a signature function, a first signature of an expected data stream associated with an input data stream that is being inputted to a design-under-test (DUT) for a datapath test. The first signature of the expected data stream can be stored without storing the expected data stream. The fuzzy scoreboard can also compute, using the same signature function, a second signature of an output data stream that is outputted from the DUT during the datapath test. The first signature can be compared with the second signature to determine whether there is a match. Storing the first signature of the expected data stream without storing the expected data stream can reduce the memory space consumed by the fuzzy scoreboard.
