I will output a hd sdi video on my board. There will be only hd sdi output, not an input on project. I used Spartan gtp wizard and triple sdi core. Everything is OK on simulation, but it didn't worked on hardware. The gtp dual tile pll didn't work fine. PLLLKDET0 net didn't go high, although it goes on simulation. On board design, I wired all the mgt power pins(but not MGTAVCCRX pin ) to 1.2 volt. As I don't need input hd sdi, I wired the MGTAVCCRX pin to ground. Is this a bad practice? Can it affect my ref clk input? Do I have to change my design?
