Hello

I replicated the simulation setup in Ansys, and I am getting a nice eye diagram in the FPD link II SER-> DES channel, however, the presence of the backchannel in fpdlinkII is a must, then is there a way from with the IBIS to generate the backchannel signal in order to have correlation between measurements and simulation?

Thanks

    Hello Nicholas,

    Our simulation models typically separate forward and back channel signaling into separate environments instead of simulating bidirectionally. However we are looking into the feasibility of adding an aggressor signal to mimic  the influence of the back channel for future models.

    Best Regards,
