[f-cpu] random number generator

["gaetan@xeberon.net" <gaetan@xeberon.net>]

Hello f-cpu world !

I'm looking for a real random generator for intensive tests on the 
floating point adder.
I would like to generate randomly a set of real numbers (single or 
double precision) and feed my adder with.

I've found someone but i don't know if I could use them (licence 
conflict??):
http://tech-www.informatik.uni-hamburg.de/vhdl/packages/mathpack/mathpack.vhd
this is a MATH_REAL package for ones (like me) who doesn't have the 
expensive math_real from ieee.

I don't really need a complex one, just something to avoid me to type 
every constant...
and an other problem is the seed: is there a "time()" function in vhdl, 
or anythig else to "pseudo-random" initialize the generator...
I'm under windows so i don't have /dev/random  >:o ...

the random package in the source tree just read a file... i will use it 
if i don't find anything else but i don't really like it...

thanks,

so i go back to my adder

byebye
