Hi Dlim,
I think that you understand my expected placement about fPLL and Native PHY.
I attached excel file you suggested.
I seem that the pin placement in qsf is same as the pin placement in pin.rpt(actual).
Row P:User Pin assign from qsf
Row Q:Actual Pin assign from pin file
I don't configure the clocking network to x1, but "bonded x6".
I had additional questions, when I edited an excel file.
I configure pins as below.
-reference clock:I/O standard=LVDS
-transceiver PHY output:I/O standard=High Speed Differntial I/O
-transceiver PHY input:I/O standard=Current Mode Logic(CML)
I refer below URL
In section 5.1.1.2, transmitter buffer should be "High Speed Differential I/O".
In section 5.1.2.1, receiver can be selected High Speed Differential I/O or CML or Differential LVPECL or LVDS.
Which I/O standard should I select ?
I can not find the DC specification about High Speed Differential I/O,CML ,Differential LVPECL ,LVDS.
BR,
