hi, i'm running into similar fitter error with my cyclone v design with transceiver using quartus 15.0.150, with quartus 14.1 my design does not have these errors

do you use quartus 15? maybe 14.1 worth a try and plz give a feedback because i'm also struggling with this error and can not get my design working with quartus 15 but 14.1 it works fine

I use quartus14.0.

I have not yet solve it. I use fpll to support the sdi refference clk.
