Syed,

This is good news indeed.  I have no doubt that AMS can be used to model 
pretty much anything in the Analog world. As I said previously:

The question is not whether an AMS language can provide full modeling ... , it is rather whether the problem can be abstracted to a model order reduced level where an AMS simulation has a performance advantage over SPICE, with near-equivalent accuracy.

As soon as you are able to share the information in the paper, I will 
look forward to reviewing your results.  I will be especially interested 
in the following correlations:

    * waveforms of driver and package driven directly into the perfectly
      terminated input of 20 GHz or greater bandwidth DSO,
    * measurements of driven waveforms at various different common mode
      DC operating points,
    * TDR measurements of the driver and the receiver,
    * waveform measurements of short low loss channels with high return
      loss near the Nyquist frequency,
    * noise impacts on the recovered signal at the receiver,
    * and SSO/SSI and crosstalk effects that were modeled.


best regards,

Scott
