	  1G Serial Ethernet设计实例说明
-------------------------------------------------------------------------
目标器件:GW5AST-LV138FPG676AES
---------------------------------------------------------------------------
1、1G_Serial_Ethernet_Readme即本文档是文件结构说明。
2、 project中是调用1G Serial Ethernet IP Core的工程，工程中的IP Core选择Quad1的Lane3，使用Q1 REFCLK0的100MHZ作为参考时钟，经QPLL1产生时钟，支持MAC层功能。
3、simulation中是vo仿真的脚本。
4、tb中是仿真文件
5、仿真说明：
       modelsim仿真：
（1）	打开modelsim软件
（2）	进入目录simulation/modelsim
（3）	运行命令do cmd.do
   vcs仿真：
（1）	在simulation/vcs目录下运行vcs.sh，即可开始仿真并生成.fsdb文件
（2）	在simulation/vcs目录下运行verdi.sh，即可使用verdi软件查看波形

	  1G Serial Ethernet Design Read Me
-------------------------------------------------------------------------
Object device: GW5AST-LV138FPG676AES
---------------------------------------------------------------------------
1、	The "1G_Serial_Ethernet_Readme" is a structure description of the files.
2、	The FPGA project in the directory “project” is a fpga case which designed with 1G Serial Ethernet IP Core. The IP Core in the project selects Lane 3 of Quad 1, uses the 100MHZ of Q1 REFCLK0 as the reference clock, generates the clock through QPLL1 and supportes MAC layer functions. 
3、	The files in the directory "simulation" is a script of the vo simulation.
4、The files in the directory "tb" is the testbench and the library of the vo simulation.
5、Simulation description:
	modelsim:
(1)	Launch modelsim 
(2)	Change directory to “simulation/modelsim”
(3)	run “do cmd.do”
vcs:
(1)	run “vcs.sh” in directory “simulation/vcs”,the script can run simulation and creat .fsdb file
(2)	run “verdi.sh” in directory “simulation/vcs”,the script can lauch verdi and view wave
