Cdence PSS+PAC analyses

Hello,
I have to evaluate the input impedence of a time variant device, to make this i used PSS+PAC, after the simulation in direct plot with pac analyses i can plot the current or the voltage, but i have to plot the impedence...i thought to use calculator and the command vf and if , can i use this command also for pac analysis?? However if i use this command i see anything...

Help me please...

Hi,

Have you tried giving equation while punching the output in the spice deck itself? If your simulator allows this, you can directly plot the impedance.
