Cadence SFDR and ENOB simulation for DAC/ADC over frequency and input amplitude

Puppet123 · Apr 6, 2020

Hello,

I am using Cadence Spectre/Virtuoso IC5.1, so I dont have access to the new Spectrum Assistant.

I want to use Cadence Spectre/Virtuoso to plot SFDR and ENOB for a DAC (but also for an ADC later) over frequency and input amplitude.

Is there a way to do this using calculator and parametric analysis ?

Thank you.

Use skill function.
It is very easy task, if you can understand definitions of SFDR and ENOB truely.

This is very true for https://www.edaboard.com/showthread.php?386455#8

Can you post some example SKILL code that accomplishes this ?

I notice you talk a lot about SKILL and OCEAN coding, yet you never post any code.
