    waveform processing question in Virtuoso ViVA Reply

    My system: Cadence IC615

     Sometimes when I do a DC sweep, I need to rearrange the X and Y axis.

     For example, in a voltage DC sweep, I got two signals shown on the viva. Var1 vs voltage, and Var2 vs voltage. In these two graphs, both have voltage as X axis. But if I want to see hwo Var2 varies with regarding Var1, meaning Var1 is my X axis and Var2 is my Y axi,. is it possible to do this in viva? I know I can export the raw data to Excel and draw from there. But if viva can do it then it will save some processing time.

    Thanks!

    I very very quickly took a look at your question....  Is this what you are looking for? 

    How to plot a design parameter versus an other in Wavescan/VIVA ?

    Hi Tawna,

    Actually that solution isn't quite right for the Qt graph version of ViVA introduced in IC615; it's valid for IC614 and before (including IC5141). In IC615, you can plot the two waveforms, and then with the mouse over the x-axis, do Right Mouse-> Y vs Y.

    The second document shows how to use the Y vs Y button in the results browser as an alternative way of plotting it from the results browser.

    Regards,

    Andrew.
