Re: [oc] pseudo random generator verilog code source

[Lars Segerlund <lars.segerlund@comsys.se>]

  If you got some ram to spare you might want to check out the Mersenne 
twister pseudo random generator, since it's got really good metrics, 
otherwise you might want to try 'ent' a little program to calculate the 
entropy of the generated sequence in order to some extent verify the 
quality of the implementation.

  / regards, Lars Segerlund.
