    Hi

    The combination of settings need to satisfy certain rule:
    Please refer to Arria 10 Pre-Emphasis and Output Swing Settings spreadsheet for selecting legal pre-emphasis and differential output voltage settings. I've attached the excel spreadsheet.

    For example, the following setting is illegal based on the .xls file. The setting value will change to red color if it is not valid.
    "2nd Pre-Tap Pre-Emphasis =0;
    1st Pre-tap Pre-Emphasis =0;
    Output Swing(VOD)=11;
    1st Post-Tap Pre-Emphasis=0;
    2nd Post-Tap Pre-Emphasis=0"
