* Signals into D-FF U8,U3,U2 all had the same net names ( DFF_CLK_P<0> etc. ) would have wired all inputs together. Very wrong * One of biasing resistors for D-FF input wasn't connected. * Diff pairs into FPGA connector inverted ( P<--> N ) AUXIO_7 pair , DATA_FROM_UPSTREAM_<1> pair, TIMING.UPSTREAM_DATA_<2> pair. Pointed out by Pete Hastings * To Do: Clock to FPGA from clock generator not connected. ( Whoops !)
