Hi experts, Does anyone know why the SATA committee chose to add 14 sigma to Dj, in order to determine Tj at an effective BER of 1e-12? I'm looking at a table of the erfc function, and it's telling me that erfc(14) = 3.0372e-87! (I would've expected that they would've chosen `n', such that erfc(n) = 1e-12.) Thanks!
