It isn't.  See http://www.kth.se/en/csc/forskning/small-visionary-projects/tidigare-svp/fa-en-konstgjord-rost-att-lata-som-en-riktig-manniska-1.379755

On the underlying issue of whether a software model of a hardware RNG could be accurate enough for ... some not-quite-specified purpose:  Gate-level simulation of circuits is a simple off-the-shelf technology.  If the randomness is coming from below that, you need more accurate simulations, but *no one* builds a chip these days without building a detailed physical model running in a simulator first.  The cost of getting it wrong would be way too large.  Some levels of the simulation use public information; at some depth, you probably get into process details that would be closely held.

Since it's not clear exactly how you would use this detailed model to, say, audit a real hardware generator, it's not clear just how detailed a model you would need.
