1. A method of testing a serial interface comprising:

  • storing an output word into a first register;

    creating an output stream by repeatedly recalling said output word from said first register;

    passing said output stream through a scrambler to create a first pseudo-random sequence within said output stream;

    passing said output stream through a transmitter;

    looping said output stream back into a receiver;

    passing said output stream through a descrambler to descramble said first pseudo-random sequence within said output stream to generate multiple input words;

    comparing each of said multiple input words to said output word in said first register to determine any errors;

    storing said errors into an error register; and

    evaluating the performance of said serial interface by at least in part evaluating said errors in said error register.
