Arpad, Rx_Receiver_Sensitivity is similar to Vdiff in normal differential models. Vdiff is applied in IBIS at the Rx pad of a simulation. Rx_Receiver_Sensitivity is applied at the receiver decision point. After equalization (the waveform output of Rx AMI_GetWave) is sampled at the clock ticks returned from Rx AMI_GetWave. If the signal at the clock tick is > Rx_Receiver_Sensitivity the value of the signal is "1", if < -Rx_Receiver_Sensitivity it is a "0", if between -Rx_Receiver_Sensitivity and Rx_Receiver_Sensitivity an error.

This parameter is Type Info, meaning that it is not passed to the DLL, it is only information for the EDA tool. The question is, what is the tool supposed to do with this? I assume that if the DLL is written correctly, it would account for this sensitivity parameter in its algorithms (for example in CDR), so the EDA tool wouldn't need to adjust the returned times for the threshold (in)sensitivity. Is the EDA too expected to do anything with the returned waveforms when displaying eye diagrams and/or BER plots, etc...? If yes, what should be done? If no, what is the purpose of this parameter?
