Manipulate and copy from parametric analysis plot

BaaB

I am using parametric analysis to plot the curve Vout with time for different Vth values. The plot is in the figure below.  The X axis is time, Y axis is voltage Vout. From the graph result, if I put a vertical marker at the point where the circuit reaches steady state period, then on the left (in red circle) you can see two columns V1 and Vth which is sample of Vout with different Vth at this particular time. 

From this I would like to plot the curve Vout vs Vth. Is there an easy way to do that?

Also how to copy the two columns into Excel so I can plot it by Excel if we can't plot it by Cadence tool?

I know that I can retype the two columns into Excel one by one and then plot but that would be too slow and take a lot of time. So I am searching an efficient method than that.

Thanks.

    Hi Huan,

     Select the x-axis in ViVA and then do RMB->Swap Sweep Var... . In the window that pops up, fill it as shown below:

    Sweep Variables : vth

    Plot Destination: New SubWindow or New Window (whatever you like) 

    X Value: 368.26739u

    Click Ok and Vout vs vth should be plotted at t=368.26739us (point where the circuit reaches steady state period). If you select the new wave (Vout vs vth) and do RMB->Symbols On you can see that symbols are displayed on the wave representing the y,x values of Vout,vth.

    Regards,

    Dimitra
