hello sir,
presently i am working on to convert the temperature to frequency in a cadence EDA tool.
Actually i am getting problem on how to plot the temp vs frequency in cadence
plz sir help me , i hope you will be concern me
thanks in advance

I've never tried to sweep temperature, but I often use
Parametric Analysis to step it and plot stuff. Perhaps
the problem is in getting frequency as a scalar value.
My version of Calculator has a freq function that can
be used on transient simulation results. I have also
used a veriloga "widget" to generate a voltage proportional
to frequency. Maybe one of these approaches will
work for you.

What exactly are you trying to measure? A temperature vs. frequency plot sounds like you want the temperature of your circuit vs. the input frequency, which I don't think is possible in Cadence.

You can get Frequency vs. Temperature, though. Temperature in Cadence is the temperature around the system. On the output you can then use the frequency function on a waveform, as dick_freebird mentioned. You can then change temperature with a parametric sweep by making the temperature a variable and using Tools -> Parametric Analysis. This will generate a Frequency vs. Temperature graph.

Hope this helps!
