FPGA logic design of SATA3.0 physical layer

In this paper, we present a SATA physical layer design based on kintex-7 serial FPGAs. This design uses the GTX of the Kintex-7 to interface with SSD devices at SATA 3.0(SATA3.0, 6 Gb/s) speeds and compatible with devices with SATA 2 and SATA 1 speeds. A brief introduction of SATA physical layer protocol is given in the first part of this essay, then we have an quick view of the GTX of Kintex-7 and function block of physical layer design, at last, we illustrates the correct function of this design using a Xilinx KC705 evaluation board.
