基于国产FPGA的千兆以太网交换机复位系统设计

Design of Reset System Based on Domestic FPGA for Gigabit Ethernet Switch

针对以太网交换设备的国产化需求,研究了千兆以太网交换机复位系统的实现原理,分析了以太网交换机复位系统软硬件设计的实现过程,提出了千兆以太网交换机的复位设计方案,并给出了一种基于国产FPGA的千兆以太网交换机复位系统,通过软件对FPGA复位程序进行了仿真。仿真结果表明,该设计符合千兆以太网交换机的复位时序要求,能满足国产化千兆以太网交换机的设计需求。

To address the domestic demand for Ethernet switch,a reset system for gigabit Ethernet switch is studied,the implementation for the reset system with software and hardware is analyzed,and a reset scheme for gigabit Ethernet switch is proposed.Finally,a reset system based on domestic FPGA for gigabit Ethernet switch is designed.The code for FPGA is simulated with software,and the simulation results indicate that the design meets the timing sequence requirements for gigabit Ethernet switch,which meets the expected design requirements for domestic gigabit Ethernet switch.
