Arria 10 IBIS AMI model selector for supporting VOD setting 12.

Hello,

I had arria 10 IBIS_AMI model and try to simulate transceiver output with "A10_V12_R100_SLEW4" model selector option.

I am using HyperLynx.

By the excel file(arria-10-cyclone-10gx-pre-emphasis-and-output-swing-settings.xlsx) from Intel, I expect 330mVp-p output w/o no pre and post tap.

But I always have 1Vp-p at the transceiver output with HyperLynx tool.

please let me know how I could have consistent result between excel file and Arria10 IBIS-AMI with HyperLynx.

    Hi Vincent,


    There is a possibility the VOD has not been set as 12 even though you are setting it. Please check once are you correctly setting the VOD, VCCT and data rate?


    Thank you

      I set VCCT, VCC and data rate correctly and changed VOD by selecting corresponding model by model selector.

      But I could not have any difference.

      DO you have any sim result with this IBIS_AMI model in any simulator to clarify the VOD amplitude?
