Quartus simulator random input algorithm

Hi,

I would like to know with what method or algorithm are the random input numbers of the quartus simulator are generated? For example in hardware, LFSRs are used with an initial seed. I need to know what algorithm is used in Quartus for generating random input vectors.

Could you elaborate the algorithm for PRNG and if it is completely random or not and why.

Thanks.

    I dont know what algorithm it actually uses, but if its like the uniform() function in the math_real package of VHDL, then the source protected by copyright. But that uses 2 seed values.
