Spectre MDL help for "sp ... donoise=yes" analysis

Hi,

I am running MMSIM 15.10.766.

mdlref.pdf says that MDL supports sp analysis. I am able to use MDL with sp analysis to extract the S parameters.

I am not sure MDL supports sp analysis with noise analysis, i.e. "sp ... donoise=yes", or how to extract the noise parametes from the simulation results.

A sample netlist is attached at the end of this message. Run a simulation, and a .s2p file will be generated with noise parameters at the end of the file. How do I use MDL to access/obtain the noise parameters (e.g. noise resistance) as shown in the .s2p file?

Thanks.
