----------------------------------------------------------------------
使用说明：
	1、板测：使用云源软件打开上述文件中Ref_design.gprj，设置工程顶层模块，将data设置为加载路径，综合；根据所使用器件设置约束和gao.v后布局布线后下载测试。使用GAO抓取数据。
	2、modelsim仿真：仿真脚本存放于Modelsim文件夹中

	注：tb文件夹下prim_sim.v仅供参考，建议用户根据情况在仿真时使用最新版替换。

Instructions:
	1、Onboard test:Launch GowinYunYuan and select "File -> Open -> Project", set Top Module and Include Path. After Sythesize, cofigure Physical Constraints and GAO Config Files.
	2、modelsim simulation:Use script in Modelsim folder.

	Note: The prim_sim.v under the tb folder is for reference only. It is recommended that users replace it with the latest version during simulation.
