Hi,

When I have tried IBIS model assignment for TS3DV416, there are some errors which I have included below:

How can I remove this error?

    Bhavya,

    I will move this post to the modeling forum to help you with your model issue.

    Thank you,

    Hello Bhavya,

    Thanks for your inquiry. Please note that the IBIS model is compliant to IBIS specification. It passes committee parser with no error.

    I believe what you report is caused by the simulation tool not being able to interpret the [Series Pin Mapping] per IBIS specification. Which software are you using?

    I’ve modified the file to work around what the tool complains. Please see the attached IBIS file.

    ts3dv416.ibs

     The changes I made are highlighted in red below (pdf file). Essentially, I had to comment out the duplicate series pin mapping. However, please keep in mind that the original modeler’s intention was to implement a different model for each signal direction (for example, from pin2 to pin48 vs. pin48 to pin2). So if you are interested in signal direction path from pin48 to pin2, I suggest you comment out the first half of the sections (in blue) and comment in remaining sections (in red).

    I hope this helps.
