XF is a small signal analysis. It gives you the transfer function from
any source to one selected output in one run.

spectre -h xf

XF will give you the transfer function from each pin (you need an
independent source from ground to the pin) to the output (if you select
it in the analysis setup form). Then plot(20dB(VF("/inp")-VF("/inm")))
