We can plot Timing Bathtub Curve, that is, Horizontal Bathtub Curve from Eye Diagram in recent Cadence ViVA. Here eyeBERLeftApprox() and eyeBERRightApprox() are available for this purpose.
However we also have to plot Amplitude Bathtub Curve, that is, Vertical Bathtub Curve.
And we need BER Contour Plot.
How can I plot Vertical Bathtub Curve and BER Contour Plot in Cadence ViVA ?
Attached figure is a result of Keysight ADS. Actual Instruments also support Both Horizontal and Vertical Bathtub Curves, BER Contour Plot.
