Test Solution for a Random Number Generator

摘要

A random number generator and method for testing the same are described. In one embodiment, the random number generator comprises one or more ring oscillator structures, each of the one or more ring oscillator structures having a ring oscillator for use in generating random numbers and having a test structure to reconfigure the ring oscillator into a testable structure.
