Histogram Bathtub View
Bathtub Curve is also referred to as an "error probability density plot." This plot is derived from a convolution
of DJ and RJ values from TailFit. The following plot shows a view of the long-term reliability of the signal
under test. Total Jitter (TJ) is extracted directly from this plot and is a peak-peak value at a specific bit error
rate or number of clock cycles. The TJ value is read from the curve at the point that the color turns to gray.
The Y-axis represents a number of cycles of the clock.
