Write your iip3 equation in the outputs menu and then make your simulations by changing bias current utilizing parametric simulation.So, when you change bias current, for each step PSS+PAC will calculate iip3 and you'll obtain iip3 vs bias current curve.

When OIP3 simulation is done, max. output power for each carrier should be 20dB lower-at least- than P1dB Output Power hence xIP3 equation is still valid.
Let's say an amplifer G=20dB and P1dB=30dBm
Maximum allowable input signal(s) for OIP3 simulation will be
P1dB-20=>10dBm-Gain=-10dBm for each.

I don't think there is a formula to calculate die size just based on gate count and RAM size. If you look at most chip, you will see that about 25%~40% of die size is used for just routing purposes. That means die size depends largely on unknown factors such as cell library used, routing tools, and maybe experiences of routing engineers. You can on

softwares or tools can calculate
Green's function, either simbolically
The input should not be limited by
planar structure and symmetric structures.
It is powerful if it can solve general cases.
If there is no such software,
maybe it is a good topic for research.

There are several possibilities:
1.) Look for zero-crossing on both channels. Measure the frequency (time from zero-cross to zero-cross multiplied by 2) of one channel. Measure the difference between the zero-crosses (identical edge) of both channels. So you can calculate the phase shift.
2.) Transform the input-signal to a logical

You have to calculate it yourself, but you only calculate it once. You may need several tables for situations where the signals are uncorrelated and for when they are the same signal at different phasees.
Use the same method you now use. Make one signal 0 dBm and the other from 0 dBm down to how many -dBm it takes to get an addition of 0.01 dB

Of course, fourier transform should be done to the voltage and current, because impedance is a frequency-domain parameter.
To calculate current, use the equation
I=integral along a close path (Hdl)
set a close path that include the trace(in the cross secton view). apply the above equation to obtain the current in the trace.
