Hi SI Gurus,
We are considering the following options in order to reduce the EMI of one of 
our boards, which is mainly caused by the PCIe Gen3 link:

1.       Reducing TX swing.

2.       Turn on SSC.

3.       Slowing down edge rate.
While we are running test to verify which option will bring us the best result 
& least impact, any comments or suggestions from those who had experiences on 
this matter?

Best Regards,
