Plot large signal conversion ratio of a simple dc-dc converter

BaaB

I would like to plot large signal conversion ratio of a simple dc-dc converter such as boost converter. How can I do this?

The plot should be something like the picture. Thanks.

    You might be able to use the information in my app note. That talks about simulating DC to DC converters using SpectreRF - and maybe you could sweep the duty cycle.

    Thank you very much, Andrew.

    Reading that app note, I am still not sure if PSS can be used to plot the conversion ratio with duty cycle as the picture above. I tried another method that set duty as a variable and then run parametric the duty variable in transient analysis and plot conversion ratio M =  Vout/Vin. 
    With this I got a set of curves Vout/Vin with time for different duty cycle. However, there are some problems. 

    First, I only want to calculate conversion ratio M = Vout/Vin at steady state and transient period. Second, I would like to plot duty cycle as X axis not time. 

    Could you give me some advice?
