CMOS RFIC substrate ground

Hi

 

I want to simulate a RFIC inductor layout in CMOS technology. During EM simulation which layer will be used as a GROUND, since in RFIC several metal layers and substrate itself can be assigned a ground?

 

I have seen some places where infinite ground is defined at bottom of substrate ? What kind of applications determine this approach of assigning ground at bottom of substrate ?

 

Regards

Vipul
