Title: Vertical Bathtub Curve in Cadence ViVA
Post by cheap_salary on Aug 7^th, 2018, 3:50am

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.

Not currently. It's a good suggestion though - could you please contact Cadence Customer Support so that we can plan this enhancement with R&D?

Regards,

Andrew.
