HI,evrybody.I'm newer in here.I want to use EP3C5E144 generate sdi test parttern.Can you give me an example?

Firstly, generate a stream using test pattern generator(8 or 10bit stream + 27MHz clk + data valid signal), then use SDI megacore to generate SDI output. It requires 27MHz input clock (You must use the same as for the video parallel stream mentioned before) + 270MHz reference clock from the PLL of the 27MHz (ratio 10/1), if You're trying to generate SD SDI.

yes,I just do it as socrates said.I use a vip test parttern,it's clk is 27MHz,10 bit,720X576,YCrCb,4:2:2.And I use SDI megacore generate SDI TX,it'clk si 27MHz and 270MHz.But the can't work.why? 

my question is the SDI core can generate EAV&SAV?An other example use a verilog make sdi frame.I use the SDI core need use make sdi frame myself or not?
