fft (dft) in spectre

Hi,

I have a layout of a gilbertcell mixer and i have to verify its
functonality . I need to plot the frequency vs magnitude of the o/p
signal . How do I do it in Spectre. I used DFT function from the
calculator but not sure if the results are correct . I got a plot of
time vs magnitude when i plotted the DFT of my o/p . How do I get the
freq vs mag plot . Am I using the correct function for my problem?????

You could use the PSS to simulate it. If you use the tran and then use dft
to plot the freq. domain. It is okay too.
