How to put X-axis into a variable related to the sweeping variable rather than the sweeping variable itself (by default) in the Cadence Waveform?

Alex Liao

Hi All,

I have a question related to Cadence waveform....After i do the DC sweep simulation, I want to plot 

gm/id VS id/(w/l)


Eg: If i sweep W (width) of a device and now i only can plot gm/Id vs W in a straightforward way as the W is the sweeping variable default set as the X-axis.

When w changes, the id changes. So what I want is like sweeping w, rather putting it(w) directly into X-axis, put a function [ f(w)=id/(w/l) ] into X-axis (no bother to Y-axis).



Any suggestions??

regards,

Alex.

  • Hey Andrew,

    I have checked it again, the subversion is IC6.1.6.500.9. (Guess it is called ISR9). According to what you said, the waveVsWave should exist in the Cadence Tool, but just not added into the calculator (guess subversion 12 is later than subversion 9 and that's why I did not find it in the calculator in my subversion). So where can I find and use this waveVsWave function in the Tool? Just want to know more about Cadence, an alternative way to do things.

    Thanks,

    Alex.
