Figure 20 shows the waveform diagram of a typical BIST test for two cases. Case 1 is error free, and Case 2
shows one with multiple errors. In most cases it is difficult to generate errors due to the robustness of the link
(differential data transmission and so forth), thus they may be introduced by greatly extending the cable length,
faulting the interconnect, reducing signal condition enhancements (De-Emphasis, VODSEL, or deserializer
Equalization).
