1. A method of testing an electrical component, the method comprising the steps of:

  • performing a first test in a known environment;

    calculating an expected Cyclic Redundancy Checker (CRC) value over a predetermined amount of memory after completion of the first test;

    performing a second test on a device under test, the second test being substantially equivalent to the first test;

    calculating an actual CRC value over a predetermined amount of memory after completion of the second test;

    determining whether the expected CRC is substantially equivalent to the actual CRC;

    upon a determination that the expected CRC is substantially equivalent to the actual CRC, indicating that the electrical component passed the second test; and

    upon a determination that the expected CRC is not substantially equivalent to the actual CRC, indicating that the electrical component failed the second test.
