1. Automatic test equipment for testing non-deterministic packet data from a device-under-test, the automatic test equipment including:

  • a memory for storing expected packet data;

    a receiver for receiving actual packet data from the device-under-test; and

    a data validation circuit coupled to the receiver for validating the non-deterministic packet data based on the expected packet data from the memory, the data validation circuit comprising a first-in-first-out circuit having an input coupled to the receiver and a match circuit having a first input coupled to the first-in-first-out circuit and a second input coupled to the memory.
