I am trying to generate 1 gbps prbs from GTx transceiver on Kintex7 KC705 board. I found a zip file having example_design with ready_to_download bit file. The bit file I think is having a 10 gbps prbs generation but I require 1 gbps prbs.
I tried to synthesize the ipcore for 1 gbps. It gave me a bit file which when I load into fpga does not generate any sequence rather I get a noise like waveform. I have attached that .bit and .ngc files herewith. The waveform lookes as follows:
I think that the transceivers are not generating prbs at all.
I also, tried to synthesize the vhdl code with ucf file given in the example_design folder but it gives errors in ucf file in implementation phase. I have attached those vhdl and ucf files herewith. Please explain the flow for using those example_design vhdl files for generating programming bit file.
