    Co-simulation with S-para block Reply

    Hi all.

    I want to simulate a channel that will be compared with measurement.
    For influence of cable, I've insert the PART with S-parameter.
    The PART is measured result of cable by VNA.

    Who has this kind of experience?
    The simulation result looks strange.
    Is this correct result? The offset voltage is coming down from 0 to -100mV.
    In the event, the amplitude is same.

    Green Waveform is the result without S-para Block.
    Red Waveform is the result with S-para Block1.
    Black Waveform is the result with S-para Block1.

    Thanks for any information.
    Best Regards,
    YS Shin

    [correction]
    Green Waveform is the result without S-para Block.
    Red Waveform is the result with S-para Block1.
    Black Waveform is the result with S-para Block2.

    Have you checked your measured S parameters for passivity? Read the S parameter Application note in the Cadence documentation package or on the SourceLink site. If the measured S parameters are not passive, and it is hard to get fully passive measured parameters due to calibration and probing errors, you can get interesting time domain effects.

    I've tried to run same S parameters using Hspice.
    It worked very well.
    Have you ever seen this kind of problem?
