11/21   How do you create a digital watermark? thx - jng
        \_ Do you mean an IP watermark for digital circuits in
           FPGAs? You look for unused entries in LUTs and encode
           a fractal like digital watermark in those entries and
           then add fake logic that actually uses these LUT entries
           but doesn't do anything with it. - sagarwal
