Hi Radovan: I would have to see the original IBIS file to give you a precise answer. The earlier verions 4.2.0 and below actually had bugs because it failed to detect certain cases where threshold subparameters under [Receiver Thresholds] was needed. They also had other problems where even correct information was flagged as an Error or Warning. So the previous report with 0 Warnings was incorrect. The report with version 4.2.1 now indicates that there is missing information. Note, when the correct information is put into the model, you will probably get Warning or Error messages with version 4.2.0 and lower. These messages are incorrect. The reason is that we did not take into account all combinations with single-ended and differential specifications that could occur using [Diff Pin] and [Model Selector]. The complicating factor is that a model could be configured independently as a single-ended buffer or used in a differential buffer. I believe the Warnings now indicate that you are using one of the buffers in a differential configuration through [Model Selector], and the selected [Model] does not have the differential subparameters under [Receiver Thresholds].
