Noise Parameters

The noise characteristics of active devices are often specified with the four "spot" parameters: F(min),G0,B0,RN.  I have read how GENESYS uses the "noise correlation matrix" approach for noise modeling.

My question: "Is their a direction implied for GENESYS noise analysis?"

For example, suppose I build an microwave amplifier around a FET.  It is straightforward to use GENESYS and spot noise data from the FET manufacturer to calculate "forward" Noise Figure(NF) for the amplifier.  -by "forward" I mean from input-to-output.

Would it make sense to use GENESYS to calculate the "backward" noise figure for the amplier (ie. from output to input)?
