摘要

GTX是一种高速串行收发器,具备高速率、低功耗的特点,可用于实现收发双向独立传输。在Xilinx的Virtex6FPGA中灵活配置,且与其他逻辑资源紧密联系。在Cadence Sigrity环境下调用GTX的IBIS模型,添加从PCB板提取的S参数,对Virtex6 FPGA GTX收发器进行信号完整性仿真,模拟真实应用环境,对接收眼图进行分析。仿真结果证明,GTX能够实现在6 Gbps以下数据速率的高可靠性传输,能够满足大容量高速数据传输的要求,通过修改过孔,提出了一种优化传输系统的方法。
        GTX is a high-speed serial transceiver, it has such characteristics as high speed and low power consumption and can be used to implement Tx/Rx two-way independent transmission. GTX is flexibly configured in Virtex6 FPGA of Xilinx and closely related to other logic resource. By calling the IBIS model of GTX and adding S parameter from PCB board, the signal integrity simulation is performed for Virtex6 FPGA GTX transceiver. The actual application environment is simulated and the received eye diagram is analyzed. The simulation results show that GTX can implement high-reliability transmission in the data rate of less than 6 Gbps, and meet the requirements of large-capacity high-rate data transmission. By modifying the via, an optimization method of transmission system is proposed.
