3.3.1. 基础模式的仿真结果

生成的实例测试台是动态的，并且具有与IP相同的配置。

基础模式或者纯流（pure streaming）模式下，流量发生器生成10,000个字，并在TX和RX链路建立后发送到IP。随后这些字被环回到RX MAC。然后RX MAC将这些字发送到流量检查器进行数据验证。您可以在仿真结果中找到以下信息：
  • TX和RX链路状态
  • IP的配置设置
  • 每突发传输的字数
  • 测试结果，以及传输的总字数和链路延迟值

以下是每个设计实例变体的仿真结果示例。

基础传输模式下使能RS-FEC的PAM4的仿真结果

注： 使能RS-FEC的NRZ变体具有与使能RS-FEC 的PAM4变体相似的仿真结果。
