Part Number: DS100RT410

Hello,

I am trying to use the DS100RT410 ibis model in hyperlynx its it is giving a bunch of syntax errors. See below.

Thanks,

John 

"Error : DS1xxRT410

    Hi John,

    Can you try removing the [Repeater Pin] definition from the .ibs file? Let me know if this resolves the issue.

    Thanks,

    I fixed the model. It did not like that the name LLP48 DS1xxRT410 had a space in it so changing it to LLP48_DS1xxRT410 works. Also your model has some row data after the end statement of the model which does not make sense. Simply commenting out everything after end on line 4703 works.

    I now want to understand the AMI parameter values. Do you have some kind of document describing the settings. For example the receiver has EQ_LEVEL options from 0 to 32 but no way to know what db each number represents.

    Thanks,

    John

    Hi John,

    I'm glad you were able to get the model working and thanks for sharing your solution. FYI, our IBIS-AMI models are validated with Keysight ADS and known to work in this environment. Sometimes file modifications are necessary to get the models working with other software.

    Here is the IBIS-AMI model user's guide for DS1xxDF410. The key difference between these parts is that DS1xxDF410 includes a DFE and DS1xxRT410 does not. AMI parameters between these 2 models should be equivalent.
