    Custom Mask Display in Touchstone tool


      Currently I am performing SI analysis for XAUI Interface.

      It is a 3.125Gbps link. We are generating S parameter file and analyzing Return Loss.


      In the XAUI Spec, Return loss Mask is defined as following Formula,


      s11 = –10 dB for 312.5 MHz < Freq (f) < 625 MHz, and (47-1)

      –10 + 10log(f/625) dB for 625 MHz <= Freq (f) = < 3.125 GHz


      Here, i would like to know whether i feed the equation in HyperLynx and display the Mask while generating Return loss plot.


      Please respond ASAP.
