[kelvin loi]

Hi All,
I was trying to write my own signal processing block,
howto.add_ff(), which  adds 1 to the signal. I have
followed every steps written in dawei shen's tutorial.
But i got make check error as following:

  File "./qa_howto.py", line 62, in test_003_add_ff
    add=howto.add_ff ()
