The proportion count test as described in section 4.4.2 of NIST Special Publication 800-90 has been implemented with a window size of W = 512 non-binary samples. The acceptable false-positive rate has been fixed to α = 2-20. The entropy source delivers 1-bit sample and after chosen blending method non-binary samples are created. For a min-entropy of H=8.0, default proportion cut-off value is C = 1+CRITBINOM(W, 2-H,1-α) = 13. Cut-off value is programmed in PROPTESTCUTOFF register. This test can be disabled via CONTROL.DISPROPTESTS. Failing per share proportion test is reported via STATUS.PROPTESTFAILPERSHARE.
