David,
There is more to it than RMS jitter.
In TD simulations you can include the non-linear DFE
algorithms, for example, which is simply omitted in
Statistical analysis. It's comparing apples and
oranges...
Thanks,
Arpad

Subject: [ibis-macro] Statistical vs. Time Domain BER Predictions?
Hi Experts,
When comparing the BER estimates of the Statistical and Time Domain operating
modes of an EDA tool, would you expect:
1) Statistical to estimate lower or higher BER than time domain?
2) Expect the differences between the 2 modes to go to zero, as the
difference between their estimates of RMS jitter goes to zero? (Said another
way, perhaps: are BER extrapolation errors mainly due to errors in RMS jitter
estimation?)
Thanks!
