Is there a backup non-physical source in case the physical ones fail or are persuaded to fail? If you look at the Capstone RNG, designed by guys who really know about failure modes of crypto hardware, they also have a CTR-mode PRNG driven from an internal seed, and an internal counter to ensure that some state changes occur even if the dynamic randomness-generation locks up. It's a really good belt-and-suspenders design, the sort of thing I'd do if given the chance (I'm a big fan of safety-oriented redundancy in security designs).
