Make a noise figure simulation

ICCAP can do a noise simulation. But the output result is noise voltage (noise current). I would like to know if there is way to get noise figure(NFmin), noise equivalent resistance(Rn) and optimal source impedance (Gopt) as outputs.
No one else has this question

Here is the latest response from IC-CAP development team:
This actually is a known recent requestâ€¦ Some IC-CAP model developers have asked for Noise Figure simulations capabilities in IC-CAP for model verification; Import meas. Noise Figure data (.mdm file), and then simulate with the extracted param. Deck. Â Since Noise Figure was not part of the (conventional) device modeling (what is DC->CV->Spar), a fit of the meas. vs. simul. Noise Figure is a measure of physical model parameter values.
IC-CAP development team plans to enhance the ADS-IC-CAP interface to meet this requirement in an upcoming IC-CAP releaseâ€¦ IC-CAP product development team cannot make firm date commitment at this time, but currently IC-CAP product team is targeting next major release of IC-CAP 2008 (possibly released in late 2007):
REQ406: Â â€œADS simulation provides NFmin, Rneq, Re(Sopt) and Im(Sopt). Â IC-CAP users would like to be able to extract noise parameters from these simulations. â€œ (PD180)
