Re: monte carlo and distribution functions

Sri -
I'm not sure that LRM 2.2 is clear about using system functions in 
parameter initialization.  Verilog 1364-2005, I think, started allowing
this for a few "constant" functions, such as $bits, $sizeof -- and
all the math functions $sin, $cos, $tan.  But in 1364-2005, the
arguments have to be constant_expressions, which rules out
integer variables.
