DP83822I: Abnormal Waveform on IBIS Model

The IBIS model is as attached 

DP83822_Rev A.zip

Hi Brian,

Could you provide some more detail about this waveform? Is this from one of the RX_Data pins? This issue is only seen during power down?

Regards,

Alvaro

This behavior is happened at power down, and the output_1P8 max is selected on IBIS model. 

Hi Brian,

Which pin is this output coming from? I ask because our IBIS files do NOT support simulation on the MDI side, i.e. the TD/RD pins.

Based off the 1p8 voltage level I'm assuming this is a RX_Data pin, please allow me another day to investigate. Apologies for the delay

Regards,

Alvaro

Hi Brian,

I was looking into the ibis file and frankly found a few items that raised more questions than answered.. Apologies but I need more time to go through.

Will respond again next week.

Regards,

Alvaro
