I am meaning that FPGA core supports 5 gbps and x2 lane. But I am limiting DSP at 2.5 Gbps or x1 lane setting by means of LİNK_CTRL and GEN2 register settings. And I see that negotiated link speed is 2.5 Gbps and negotiated link width is x1 as expec...

For Gen 3 and Gen 4, there are 11 presets numbered from 0 to 10 that may be used, each with its own unique signal characteristics. The preset values for each port are negotiated through link equalization until the ideal preset is chosen via phases 0, 1, 2, and 3 for all link equaliz...
