Hi All,
Since PCIe Gen3/Gen4 does dynamic equalization what is the point of
figuring out optimum preset values ? (some
For plug and play (involving System Board/Addin_Card types of PCIe Devices)
definitely it doesn't make sense because users might introduce additional
cables between RC & EP so different scenarios need different presets but if
the Root Complex and End points are on same PCB is it required to figure
out optimum preset values and override (using SW) the preset values
determined during dynamic equalization?
Note: I'm not saying Transmitter/Receiver Equalization Validation is not
needed.
